Primary Invaliding Condition (PIC)

 

This guide explains how the Primary Invaliding Condition (PIC) can affect medical discharge, pensions, compensation, tax treatment, reviews and appeals. You can read it straight through, or jump to the section that matches your issue. Some repetition is deliberate so that each section can also work on its own.

Start Here: PICs, pensions and compensation

If you have landed here, there is a fair chance you have recently discovered three things: first, the military loves acronyms; second, one of those acronyms now seems to have a say in your money, your future, and possibly your blood pressure; and third, nobody has yet explained any of this in plain English.

So that is what this page is for. This is the front door to the guide. It is the simple map before the harder detail. It is for people who have heard words like PIC, AFPS, WPS, AFCS, tax-free pension, GIP, review, tribunal, and have quite reasonably thought: “I have no idea what any of this means, but it sounds expensive.”

The short version is this. Your PIC is often the medical label that anchors your case. Your pension scheme helps decide what money may follow from medical discharge. Your compensation scheme helps decide whether you may get separate compensation because service caused or worsened an injury or illness. And a lot of the trouble starts when those systems use different words for the same damaged human being. That is really what this whole subject is about. Everything else is detail, law, forms, and the occasional ambush by a government letter.

What is a PIC?

PIC means Primary Invaliding Condition. That is the official condition said to have brought about your medical discharge or invaliding. At first glance, it can look like just another line on a form: a diagnosis, a code, a bit of medical admin, something tucked away in paperwork that nobody outside the MOD could possibly care about. Unfortunately, lots of people care about it later.

The PIC can affect what condition the system says ended your service, what pension consequences follow from that, what compensation scheme may apply, whether later decisions are treated as being about the same condition, and whether years down the line somebody starts arguing that your wrecked knee, damaged back, PTSD, hearing loss, or neurological condition is somehow not the same thing everyone was talking about before. So the PIC is not just a medical note. It is often the starting point for the rest of your pension and compensation story. Or, to put it more bluntly: if the PIC is wrong, a lot of the paperwork that follows can go wrong too.

There is also an important legal point here from the leading textbook by Andrew Bano on war pensions and armed forces compensation. The law does not only ask, “What label did they write on the form?” It often asks three separate questions: is there a real disablement, meaning some genuine loss of proper function in mind or body; what injury or condition is causing that disablement; and is that injury or condition linked to service in the way the law requires? That matters because the PIC may be only one line of the story. It may name the condition, but it does not always fully explain the actual disablement, or the service link, or the real seriousness of what happened. That is one reason why wording matters so much.

Why are there different pension schemes?

Because the MOD has never knowingly thrown away a layer of history. There are three main Armed Forces Pension Schemes for regular service: AFPS 1975, AFPS 2005, and AFPS 2015. These are not three different names for the same thing. They are three different schemes, created at different times, with different rules and different ways of dealing with medical discharge.

So one person’s case may be all about invaliding, whether the condition was due to service, and older attributable benefit rules. Another person’s case may be all about Tier 1, Tier 2, or Tier 3, future work, and whether their earning capacity is badly affected. Another person’s case may involve modern AFPS 2015 rules, old protected rights, and a mixture of old and new pension law in the same life story. Same armed forces world; very different pension systems.

Why are there different compensation schemes?

Because pension and compensation are not the same thing. This is one of the most important things to understand early on. A pension is the benefit that may become payable because of your service and, in some cases, because of your medical discharge. Compensation is separate. It is the scheme that may pay you because an injury, illness, or death was caused by service, or made worse by service.

The main compensation schemes are the War Pension Scheme, known as WPS; the Armed Forces Compensation Scheme, known as AFCS; and, in some older cases, the Armed Forces Attributable Benefits Scheme, or AFAB. So yes, one person can have a pension issue, a compensation issue, and a tax issue, all coming from the same medical condition. This is why people often become unwilling experts in rules they had never heard of while they were still serving.

The most important date in this whole subject

If you only remember one date at this stage, make it 6 April 2005. That date is the big dividing line in a lot of these cases. Broadly speaking, before 6 April 2005 usually points toward WPS on the compensation side, while on or after 6 April 2005 usually points toward AFCS.

That does not make everything easy, but it does stop people wandering into the wrong guide first. One of the easiest mistakes in this area is assuming that pre-2005 and post-2005 cases work the same way. They do not. And then there are the overlap cases, which are where this all starts to get properly annoying: injury before 2005, worsening after 2005, discharge after 2005, pension under one scheme, compensation under another, and an argument about whether the same condition is still the same condition once the paperwork gets involved. We will come back to those later. Sadly.

The three pension schemes in one simple summary

AFPS 1975 is the older world. Think invaliding, service causation, attributable and non-attributable outcomes, WPS interaction, AFAB, and arguments that can feel as though they have wandered in from a much older legal age. AFPS 75 does not use the later tier system. It asks more basic questions: what condition invalided you, was it related to service, and what follows from that?

AFPS 2005 is the scheme where the MOD tried to modernise things. Think Tier 1, Tier 2, Tier 3, gainful employment, whether your future ability to work in civilian life is badly affected, and a more structured ill-health pension system. AFPS 05 is less about old-style attributable invaliding and more about what the condition means for your future employability.

AFPS 2015 is the newer scheme. Think CARE pensions, protected older rights, transitional protection, and a similar three-tier ill-health structure in a different pension framework. AFPS 15 often matters even where someone also has AFPS 75 or AFPS 05 rights, because service can stretch across different pension eras.

The two main compensation schemes in one simple summary

The War Pension Scheme is the older compensation scheme. It usually covers injury, illness, or death caused by service before 6 April 2005. It is especially important because the legal test can be much more veteran-friendly than people expect. In the right kind of WPS case, once there is a real case to answer, the Secretary of State may have to prove beyond reasonable doubt that the condition was not due to service. That is a very strong rule. But it does not mean no evidence is needed. It means that once a proper case is raised, the law can put a heavy burden on the state to disprove service connection. That point matters. It is one of the big themes in Bano’s textbook. WPS can be very helpful to veterans on proof, but it is not magic. Records, chronology, and proper evidence still matter.

The Armed Forces Compensation Scheme is the newer compensation scheme. It usually covers injury, illness, or death caused by service on or after 6 April 2005. It is more structured, more descriptor-based, more tariff-based, and more like a machine built to sort injury into categories. That can work well where the condition is clearly described and clearly linked to service. It can work badly where the condition is described weakly, too vaguely, or under the wrong label. Bano explains that AFCS often involves a more technical causation exercise. In some parts of AFCS law, the argument is not simply whether service was involved, but whether service was the predominant cause in the way the scheme requires. So AFCS can be valuable, but it can also be fussy. A weak description at the start can cause real trouble later. Which brings us straight back to the PIC.

Why the PIC matters across all of this

Here is the core point. The PIC matters because it can affect which pension route you are treated as being under, which compensation scheme may apply, whether a later WPS or AFCS award is treated as being for the same condition, whether your pension may be taxed or treated differently, whether you qualify for a better ill-health tier, whether a later review moves you up, and whether a tribunal thinks the decision-maker even understood the case properly.

In some schemes, the PIC is the gateway to the tier. In others, it is the gateway to the causation fight. In overlap cases, it is the thing trying to hold the whole story together while several different legal systems all tug at it. So if anyone tells you the PIC is “just a code”, smile politely and keep one hand on your paperwork.

Why the wording matters so much

Because the law may care about the real condition, but administration often cares about how the condition is described. A condition can be written down in a way that makes it sound serious, service-related, clearly disabling, and central to the discharge. Or it can be written in a way that makes it sound vague, ordinary, minor, or detached from service. That difference can affect pension tiering, compensation, tax issues, whether the right descriptor is used, and how easy it is to challenge the decision later.

For example, there is a big difference between “traumatic service-related lumbar spine injury with chronic neurological symptoms” and “back pain”. Same body. Same suffering. Very different paperwork. This links back to one of Bano’s most useful points. A later, better diagnosis does not always mean a brand-new condition. Sometimes it just means somebody has finally described the same condition properly. That matters a lot in “same condition” disputes, where the system tries to say that the early paperwork was one thing, the later paperwork is another thing, and therefore the legal consequences are different. Sometimes that is true. Quite often, it is not. Quite often it is the same condition, described badly first and properly later.

The medical board paperwork matters more than people realise

A huge amount can turn on the medical board paperwork, especially the FMed 23. That is where the system records the principal condition, other relevant conditions, date of origin, place of origin, and restrictions affecting work and service. The MOD’s own guidance says this must be completed carefully because it may directly affect Armed Forces pension awards, War Pension decisions, and AFCS decisions. So the system itself accepts that this paperwork matters.

Bano’s textbook reinforces why. In both WPS and AFCS cases, the legal fight often turns on what condition is actually being talked about, when it began, whether it was linked to service, how serious the disablement really was, and whether later decision-makers are dealing with the same underlying condition. If the early paperwork is vague, the later fight gets harder. So if anyone tells you, “Don’t worry, it’s just the wording on the form,” the correct response is, “That is exactly why I am worrying.”

The real fights usually come later

Another early lesson is this: the first decision is often not the end. A weak or wrong PIC can trigger years of argument about whether the condition was described properly, whether the pension tier is correct, whether the right compensation scheme was used, whether service caused the condition, whether the wrong descriptor was chosen under AFCS, whether the condition should count as the same condition for later purposes, whether the wrong facts were used, and whether the reasons given were good enough.

This is why people end up in reviews, appeals, IDRP complaints, tribunals, ombudsman routes, and service complaint processes. There is more than one way for paperwork to keep arguing with you after discharge. There is also a point from Bano worth keeping in mind here. A later claim is not always really a new claim. Sometimes it is the same condition being better understood, better described, or corrected after an earlier mistake. That can matter a great deal. If the MOD got the label wrong the first time, it should not automatically be allowed to act as though you have returned years later with a completely different illness. Sometimes the later diagnosis is just a better explanation of what was true all along.

The most common kinds of problem

If you are new to this area, it helps to sort the likely problems into buckets. Sometimes the PIC itself is wrong: the wrong condition has been chosen, or the right condition has been described badly. Sometimes the pension consequences are wrong: the scheme has put you in the wrong tier, category, or tax position. Sometimes the compensation consequences are wrong: the wrong scheme has been used, the wrong descriptor has been chosen, or service causation has been handled badly.

Sometimes the same condition is being treated as different conditions, which is one of the classic traps, especially where pension and compensation interact. Sometimes the decision is built on a bad factual summary, which is where legal language about mistakes of fact and poor reasons may start to matter. And sometimes the process itself was mishandled through delay, bad explanation, missing records, or failure to follow the rules. Once you know which bucket your problem is in, things become a little less chaotic. Not cheerful. Just less chaotic.

Why people keep talking about “the same condition”

Because those words matter much more than they look. Across the pension and compensation systems, important consequences can depend on whether a later award is accepted as being for the same condition that caused discharge. That may affect how pension and compensation interact, whether a pension is treated differently for tax purposes, whether GIP is offset under AFCS, whether the case stays joined up, and whether one service-related condition gets split into several smaller administrative boxes.

This is another place where Bano is especially helpful. A better diagnosis later on does not automatically create a new illness. It may simply reveal what the condition always was. So if the system says, “This is not the same condition,” it is always worth asking, “Or is this the same condition, just described properly for the first time?” That is not pointless wordplay. That is often about money, entitlement, and whether the law is dealing with the real injury or a weakened version of it.

The law’s repeated message: reasons matter

One of the clearest messages from tribunal case law is that decision-makers must explain themselves properly. They cannot simply announce a result and expect everybody to salute. The courts keep coming back to the same points: identify the right facts, use the right legal test, engage properly with the evidence, explain why one category fits and another does not, and do not quietly swap the real condition for a tidier label.

That matters because a lot of bad PIC-related decisions are not dramatic or obviously malicious. They are just badly reasoned, thinly explained, based on the wrong summary, or too confident about weak conclusions. That is still enough to cause a lot of damage.

So where should you go next?

If you are trying to work out which part of this guide you need, here is the rough map. Read the AFPS 1975 section if your case is rooted in the older invaliding or attributable world, your service story is heavily pre-2005, or the live questions are about invaliding, WPS, AFAB, or attributable treatment. Read the AFPS 2005 section if your case involves Tier 1, Tier 2, or Tier 3, you were medically discharged under AFPS 05, or the main fight is about future work and earning capacity.

Read the AFPS 2015 section if your service and discharge sit in the modern scheme, you have AFPS 15 membership, or your case mixes modern rules with older protected rights. Read the WPS section if the injury, illness, or death was caused by service before 6 April 2005, or the main issue is service attribution in the older compensation system. Read the AFCS section if the injury, illness, or death was caused by service on or after 6 April 2005, or the fight is about descriptors, tariffs, GIP, or modern causation rules.

Read the WPS vs AFCS / overlap section if your case crosses the 2005 boundary, symptoms began before 2005 but worsened later, discharge came later than the original injury, or you have the uncomfortable feeling that two schemes are discussing the same body part in different languages. Read the appeals / tribunals / complaints section if the PIC is wrong, the pension decision is wrong, the compensation decision is wrong, or the whole process feels full of procedural trapdoors.

The bottom line

This whole subject becomes much easier once you understand one thing. The PIC is not just a diagnosis. It is often the place where the medical story, the pension story, and the compensation story all start trying to fit onto the same bit of paper.

If that bit of paper gets it right, you still may have a fight on your hands, but at least the systems are arguing from the same map. If it gets it wrong, you may spend years trying to prove that your own life happened the way it actually happened. Put another way, this guide exists because the PIC may be only a few words on a form, but those few words can decide whether the rest of the system opens like a door or jams like a rusted hatch.

PIC practical checklist

If the Primary Invaliding Condition, or PIC, is wrong, vague, watered down, or mysteriously transformed into something tidier than the actual medical reality, you can lose an astonishing amount of money, time, and sanity before anyone admits there was ever a problem. That is one of the clearest practical lessons to come out of the wider case law and from Andrew Bano’s treatment of war pensions and armed forces compensation. The fight is often not only about what happened to you medically, but about how the system chose to describe it, categorise it, and carry that description forward into later pension and compensation decisions.

So this is the practical section. Not the grand legal overview. Not the philosophical tour of the pension schemes. Not the tribunal sermon. This is the “right, what do I actually need to check?” guide. Because in PIC cases, people often spend months reading authorities when what they first needed was the right form, the right date, the right wording, and the right question.

The deeper legal themes still matter here. Bano’s book is especially useful because it shows that these cases often turn on distinctions between disablement, diagnosis, injury, causation, review, and legal classification that are easy to blur if you rush straight into argument mode. But before you get to any of that, there is a practical discipline that makes everything easier later: work out what kind of problem you have, get the documents, compare the wording, identify the route, and pin down the outcome you are actually seeking.

1. First, work out what kind of problem you actually have

Before doing anything else, identify the basic type of dispute. This sounds almost insultingly simple, but it is one of the most important steps in the whole exercise. Many people know that something has gone wrong but cannot yet say whether the real problem is medical wording, pension consequences, compensation consequences, or procedural mishandling. Until you know that, it is very easy to spend weeks or months firing at the wrong target.

Sometimes the PIC itself is wrong. The wrong diagnosis may have been chosen, the principal condition may have been something else, the condition may have been described too vaguely, or the real service-related condition may have been pushed into the “other conditions” box while something blander was promoted to the front of the file. Sometimes the PIC is broadly right but described badly. “Traumatic service-related spinal injury” becomes “back pain”; “PTSD” becomes “anxiety symptoms”; “neurological injury” becomes “functional complaints.” Sometimes the wording is not wholly false, but it is so flattened that it no longer carries the real legal or practical weight of what happened.

Sometimes the real issue is downstream. The pension consequences may be wrong: the wrong tier has been applied under AFPS 05 or AFPS 15, the wrong tax treatment has been used, the scheme has failed to treat a WPS or AFCS award as being for the same condition, or the interaction with GIP has gone wrong. Sometimes the compensation consequences are wrong instead: the wrong scheme has been used, the wrong descriptor or tariff has been selected, service causation has been rejected on weak reasoning, or disablement has been understated. And sometimes the whole process has simply been mishandled through delay, poor communication, missing records, failure to explain, failure to apply the right policy, or decisions built on an incomplete or misleading summary.

If you cannot yet answer which of those categories your case falls into, stop and work that out first. Otherwise you risk charging into the wrong appeal route like someone attacking the wrong bunker.

2. Get the documents before you get the outrage

This sounds obvious. It often is not. Before launching an appeal, complaint, or broader campaign of righteous indignation, get the key paperwork. In this area, a surprising number of arguments are really arguments about what was written down, what was omitted, when a wording change first appeared, or whether one branch of the system used different language from another. None of that can be checked properly from memory alone.

At a minimum, try to obtain the FMed 23 or equivalent medical board paperwork, discharge paperwork, Veterans UK decision letters, AFCS or WPS decision letters, pension award letters, occupational health reports, any relevant Appendix 18 or Appendix 27 material, consultant letters, GP and hospital evidence where important, medical restrictions, MedLims, JMES material, and any appeal or review correspondence already sent. The exact bundle will vary from case to case, but the principle remains the same: collect the paper trail before you try to critique the paper trail.

This matters all the more in light of Bano’s discussion of how these schemes operate in practice. A case may later turn on whether the relevant decision-maker properly understood the medical facts, whether a later claim was really a fresh claim or a review of the same underlying condition, or whether a condition was consistently identified across pension and compensation decisions. You cannot test any of that properly if you are arguing with a ghost. And in this area, the ghost usually has a better filing system than you do.

3. Read the FMed 23 like your mortgage depends on it

Because in a way, it might. The FMed 23 is one of the most important documents in the whole case. It is where the system records the condition affecting the medical employment standard, and MOD guidance itself recognises that this paperwork can directly affect pension and compensation outcomes. That is not a dramatic interpretation imposed from outside; it is built into the architecture of the process.

Read the principal condition box carefully. Ask whether it names the right condition, whether it identifies the most important condition, whether it is written clearly or blandly, whether the wording is medically accurate, and whether it sounds like the actual reason your career ended. Then check the surrounding entries. Are serious related conditions wrongly buried in “other conditions”? Has the principal condition been written in soft or non-committal language? Has a clearly service-related event been turned into a generic diagnosis that floats free of context?

This is where Bano’s analysis becomes particularly useful. A later, more accurate diagnosis does not necessarily mean a brand-new condition. It may simply reveal what the condition always was. That means an over-generic or underpowered PIC can do real damage later if the system starts pretending that the principal box captured one thing, while the more serious reality sat elsewhere all along. If the principal condition box says something weak and the real disabling condition is hidden in the margins, that is not a cosmetic issue. It is a major warning sign.

4. Check the date of origin and place of origin

This gets overlooked all the time, but it can be legally and practically important. Check whether the paperwork records the date of origin of the principal condition, the place of origin, and whether any operational or service context is properly captured. If the chronology is wrong, the consequences can spread far beyond the medical board itself.

Date and place can affect whether the case points toward WPS or AFCS, whether the service link is easier or harder to prove, whether aggravation during service is visible on the face of the record, and whether the whole chronology of the case makes sense. This is particularly important in overlap and straddle cases, where an injury may have begun before 6 April 2005, worsened later, and then generated pension and compensation questions under more than one regime. A weak or inaccurate date entry may later allow the system to shrug and say it is not really clear when the condition began. If you do know when it began, and the paperwork does not show it properly, that matters.

Bano’s treatment of WPS and AFCS makes this point from different angles. Under WPS, chronology and service history may interact with a much more favourable burden of proof than many claimants realise, but the claimant still has to raise a coherent case. Under AFCS, the causation exercise is more structured and often more exacting. In both settings, loose chronology can become the enemy.

5. Check whether the PIC matches the real functional problem

This is one of the biggest traps. A diagnosis can sound neat and minor while the actual functional consequences are catastrophic. One of the most important lessons from the case law, and from Bano’s discussion of disablement, is that legal systems are not supposed to be hypnotised by labels alone. The real question is often what the condition actually does to the body, mind, and ability to work.

So ask whether the PIC reflects what actually stopped you serving. Does it capture the real limits on your life and work, or is it just a diagnostic label that hides the severity? Compare it against MedLims, JMES status, occupational restrictions, day-to-day evidence, and any records showing what you could no longer do. Office duties only, unfit for safety-critical work, unable to sit or stand for long, unable to march, unfit for strenuous physical activity, restricted driving, chronic fatigue, severe mental health symptoms: if the PIC sounds small but the restrictions are huge, that mismatch is important.

This matters for pensions because tiering under AFPS 05 and AFPS 15 is about future employability, not just the elegance of the diagnosis. It matters for compensation because disablement and descriptor selection may be distorted if the condition is packaged too weakly. And it matters for later appeals because a decision-maker who starts from an understated label may never ask the right functional questions in the first place.

6. Ask the most important question: is this the same condition all the way through?

This is one of the great recurring questions in the whole area, and Bano is especially helpful on it. Take the discharge paperwork, pension paperwork, and compensation paperwork and compare them side by side. Ask whether the same condition is being described in all three, or whether you have somehow acquired three slightly different bureaucratic versions of the same medical problem.

You are looking for the classic slippages: a traumatic injury becoming “degenerative change,” PTSD becoming “adjustment issues,” a service-related knee injury becoming “general osteoarthritis,” a neurological condition becoming “chronic pain.” The question is not merely academic. It may affect tax treatment, GIP interaction, attributable benefit logic, and whether WPS or AFCS is really dealing with the same condition that caused discharge. It may also affect whether a later application is treated as a review of an earlier decision or as though you have turned up with a completely separate illness.

Bano’s discussion of “same condition” problems and review routes is particularly useful here. A better diagnosis later on does not automatically create a new condition. Sometimes it simply reveals what the condition always was. So if the system tells you that this is not the same condition, it is worth asking whether it is actually the same condition described properly for the first time. That question can be worth a great deal of money.

7. Work out which pension scheme you are actually in

Never assume. Check which pension scheme applies to the relevant service period: AFPS 1975, AFPS 2005, or AFPS 2015. The schemes do very different things, and a great deal of confusion in this field comes from people talking as though all medical discharge cases use the same legal machinery. They do not.

AFPS 1975 belongs to the older invaliding and attributable world, with its own interaction with WPS and AFAB. AFPS 2005 is the tiered ill-health system built around gainful employment and future earning capacity. AFPS 2015 adds the modern CARE structure, transitional protections, and more layering for anyone whose service crosses pension generations. Some cases are hybrid from the outset. If yours is one of them, write that down clearly. A lot of people are not in a pure single-scheme case at all, and if you do not identify that early, the paperwork will often drift toward a false simplicity.

8. Work out which compensation scheme applies

Then do the same exercise for compensation. Broadly, before 6 April 2005 usually points toward WPS, while on or after 6 April 2005 usually points toward AFCS. But do not stop there. Ask whether the case is genuinely straightforward or whether it is one of the awkward overlap cases. Did the injury begin before 2005 and worsen later? Was the discharge after 2005 even though the condition began before? Is there a pension side under one regime and a compensation side under another?

This matters because WPS and AFCS are not just different labels. They have different legal structures, different approaches to proof, and different internal logic. Bano is very clear about that. WPS can be significantly more favourable on burden of proof where the claimant has raised a proper case, whereas AFCS often involves a more technical causation analysis and, in some contexts, a predominant cause test. If you are in a straddle case, say so explicitly. Otherwise the case may keep getting treated as cleaner than it really is.

9. Check whether you are up against a deadline

This is where a lot of good cases get damaged by delay. The specific time limits vary by route, and one of the points that emerged from the earlier review against Bano is that deadlines should not be stated too baldly or too casually. But the practical lesson remains the same: identify the relevant clocks early and write them down.

There may be a PIC code appeal route under AGAI 78 and related policy materials. There may be time-sensitive retrospective medical discharge issues. AFPS 05 and AFPS 15 deterioration review provisions may have their own windows under the scheme rules. Compensation decisions have their own reconsideration and appeal routes. IDRP and complaint routes also operate within their own timeframes. So make yourself a deadline list: date of discharge, date of pension decision, date of compensation decision, date of any previous refusal, and the date by which you believe the next step must be taken. Then verify those dates against the actual rule or decision letter.

Memory is a traitor under stress. Paper is better.

10. Decide whether your issue is medical, pension, compensation, or procedural

This is where many people waste months. Match the problem to the route. If the PIC itself is wrong, the medical appeal route may be the right starting point. If the issue is that you should have been medically discharged but were not, a retrospective medical discharge process may be relevant. If the pension scheme has used the wrong tier, wrong rule, or wrong tax treatment, the IDRP route may be the real battleground. If the compensation scheme has used the wrong descriptor, tariff, or causation logic, the WPS or AFCS appeal route may be the correct forum. If the process itself has been mishandled, complaint, service complaint, or ombudsman-type routes may have a role.

This is not just tidiness. It is strategic. One of the reasons cases become exhausting is that people often take a pure pension issue to a medical route, or a compensation issue to a process complaint route, and then conclude that the system is being evasive when in fact the challenge has simply been aimed at the wrong institution. The system is still often evasive. But it helps not to give it the warm-up exercise.

11. Write down your case in one sentence

If you cannot summarise the problem in one sentence, the system will summarise it for you, and it will probably do it badly. This is one of the most underrated practical steps. Try to write a sentence that captures the legal and factual core of the problem. For example: “The wrong condition was recorded as my PIC.” Or: “My PIC was described in language that understated the seriousness and service connection of the real discharge-causing condition.” Or: “The pension scheme has treated the AFCS condition as different from the discharge-causing condition, even though they are the same.” Or: “The tier decision does not reflect the actual functional consequences of the PIC.”

That sentence becomes the spine of the case. It helps you decide what evidence matters, what route matters, and what outcome you are actually seeking. Without it, an appeal can turn into a 17-page memoir about institutional disappointment. Emotionally valid, perhaps. Legally less efficient.

12. Gather evidence in the right categories

Do not just gather “medical evidence.” Gather the right kinds of evidence. This matters because many weak decisions happen not because there is no evidence at all, but because one category of evidence is present and the others are missing from the picture. A diagnosis without functional evidence may understate the real impact. Functional evidence without chronology may weaken causation. Chronology without occupational evidence may fail to show why the condition actually ended a military career.

Think in categories. Diagnostic evidence includes consultant diagnosis, imaging, specialist reports, and GP confirmation. Functional evidence covers what you cannot do, what causes flare-ups, how long you can sit, stand, or walk, what activities are limited, what recovery time is needed, and how symptoms affect daily life. Occupational evidence should show what duties you could not do, how your role had to be adapted, whether you were office-bound, whether you were unable to deploy, and whether you could no longer drive, operate safely, or perform weapons-related tasks. Chronology evidence should show when symptoms started, when you first presented, when you were removed from duty, and what treatment happened when. Causation or service-context evidence should identify the service incidents, training, operational exposure, or aggravating circumstances said to have caused or worsened the condition. Comparison evidence should track how the condition is described across different records and where that wording changes.

This fits closely with the practical implications of Bano’s analysis. The law may distinguish between disablement, injury, and service causation, so your evidence needs to do the same.

13. Check whether the medical summary has quietly shrunk the problem

This happens all the time. The full medical records may show major symptoms, severe restriction, clear service chronology, and real functional collapse. But by the time the case reaches the decision-maker, the summary may say only “chronic pain, managed conservatively,” or “low mood and anxiety symptoms,” or “back pain with some functional limitation.” That is how cases get lost.

So compare the full report, the summary, and the decision letter. Ask what has disappeared, what has been softened, and what has been reworded into something more administratively convenient. This is one of the most important practical checks in the whole process, because a lot of bad decisions are not built on fabricated evidence; they are built on a compressed or sanitised version of real evidence.

That ties directly into Bano’s broader theme that reasons matter, evidence must be engaged with properly, and legal outcomes cannot safely be built on a misleading summary. A decision may look polished on the surface while still resting on a quietly shrunken picture of the facts.

14. If the case is about employability, force the issue back onto reality

This matters especially under AFPS 05 and AFPS 15. If the MOD says your PIC does not significantly impair civilian earning capacity, or says you remain fit for some form of employment, do not let the discussion stay at the level of airy abstraction. Ask: employment doing what, at what level, consistent with what background, sustained how, with what symptoms, for how many hours, and with what recovery time afterward?

This is where the rhetoric of “some sort of desk job somewhere” needs to be challenged. The point is not whether a hypothetical human in the abstract might perform some hypothetical sedentary task in a frictionless universe. The point is whether this claimant, with this background, this condition, these restrictions, and this symptom burden, has a realistically sustainable capacity for gainful employment. The law’s concern with the right baseline matters here, and although Bano’s focus is often elsewhere, the broader lesson is the same: categories must be applied to reality, not to wishful thinking.

15. If the case is about service causation, do not let the system hide behind vagueness

This matters especially under WPS and AFCS. If the issue is whether the condition was caused or worsened by service, ask what exactly the MOD or Veterans UK says caused it instead, what evidence supports that alternative explanation, whether they are relying on predisposition or vulnerability as though that ends the matter, and whether they have actually explained the chain of reasoning.

This is an area where Bano’s book is especially helpful. Under WPS, the favourable burden of proof does not mean the claimant can be passive, but it does mean the state may have to do much more than shrug and gesture vaguely at other possibilities once a coherent case has been raised. Under AFCS, service may still be legally causative even where the individual had vulnerabilities or multiple contributing factors, but the scheme may require a more technical analysis, including whether service was the predominant cause in the relevant sense. In either scheme, bad causation decisions often rely on generic language, unparticularised alternatives, or the faint hope that nobody will insist on an actual explanation. Be the person who insists on one.

16. Use the decision letter as a diagnostic tool

A decision letter is not just an answer; it is evidence of how the system is thinking. Read it critically. Does it identify the correct condition? Does it describe the evidence properly? Does it explain why the conclusion follows? Does it engage with the strongest evidence against the decision? Is it using the right legal test? Is it hiding behind phrases like “not considered significant” or “not accepted” without actually explaining why?

A lot of appeal points begin not with a dramatic legal doctrine but with a simpler observation: this letter states a conclusion without showing the reasoning that got there. That is often more important than people realise. One of the repeated messages in the wider case law, and reflected in Bano’s treatment of these schemes, is that decision-makers must identify the right issue and explain their reasoning sufficiently. A weakly reasoned letter is often a map of the appeal.

17. Do not confuse disagreement with appeal grounds — but do not undersell real appeal grounds either

It is true that not every disappointing decision is legally wrong. But it is also true that many bad decisions are dressed up to look more solid than they are. Real appeal grounds may include the wrong condition being identified, the wrong factual basis being used, evidence being ignored or underplayed, the wrong standard of proof being applied, the wrong legal test being used, inadequate reasoning, failure to identify the right baseline, or a misleading summary of the medical evidence.

So do not write merely, “I disagree and I am upset.” Write something closer to: “The decision relies on an inaccurate summary of the medical evidence and fails to explain why the principal discharge-causing condition was treated as not significantly impairing gainful employment, despite the recorded restrictions and consultant evidence.” That is much harder to brush aside, because it shows the argument is about law, reasoning, and evidence rather than disappointment alone.

18. Keep a clean chronology

Make yourself a one-page timeline. Include the date symptoms began, the date of first presentation, the date of any major injury or event, the date of the medical board, the date of discharge, the date of the pension decision, the date of the compensation decision, the date of any review request, the date of any refusal, and the date of any appeal.

This sounds boring. It is also one of the most useful things you can do. Once cases begin drifting across different pension schemes, compensation schemes, reviews, appeals, and several years of correspondence, people start getting lost in time. Decision-makers get lost as well. A clean chronology is the closest thing this area has to oxygen.

It also helps with one of Bano’s recurring practical themes: distinguishing a genuinely new claim from a later recognition of the same underlying condition often depends on a disciplined grasp of sequence.

19. Be precise about what outcome you want

The system loves confusion. Do not help it. Ask yourself whether you want the PIC code changed, the discharge treated as medical, a higher pension tier, tax-free treatment, a different AFCS descriptor, a revised WPS disablement assessment, a deterioration review, or a finding of maladministration. These are not the same outcomes, and they do not all travel through the same route.

If you do not know what outcome you are asking for, the system may “helpfully” answer a different question. That is one of the oldest tricks in administrative life.

20. Keep copies of everything

Everything. Not just the important things. Everything. Keep every decision letter, every appeal, every email, every form, every medical report, every note of a phone call, and every timeline update. Do not rely solely on the institution’s records. Institutions lose things. Sometimes accidentally. Sometimes in ways that feel spiritually personal.

This is one of those practical points that sounds mundane until the day you need to prove that a particular wording existed in an earlier document or that an important report was in fact sent. On that day, it stops sounding mundane.

21. If in doubt, ask: what story is the paperwork currently telling?

This is the master question. Step back and ask what story the paperwork currently tells about you. Is it the true story, or is it a flatter, safer, tidier story that suits the system better than it suits reality? Most PIC disputes are really disputes about the official story: what condition ended service, how serious it was, whether service caused or worsened it, and what financial consequences should follow.

Bano’s work is helpful here because it repeatedly shows that classification, wording, causation, and review are not separate technical curiosities. They are all different ways of asking whether the legal record corresponds to the real injury and its consequences. If the official story is wrong, your job is to identify exactly where it went wrong and how. Not just morally or emotionally, but document by document.

22. The ultra-short emergency version

If you are exhausted and need the shortest possible version of this checklist, start here. Check your FMed 23. Check the PIC wording. Check the date and place of origin. Check whether the PIC matches the real disabling condition. Check whether the same condition is described consistently across discharge, pension, and compensation paperwork. Check which pension scheme applies. Check which compensation scheme applies. Check whether you are within any relevant appeal or review window. Check what evidence proves diagnosis, function, chronology, and service connection. Then decide what exact outcome you want.

If you do those things first, you are already ahead of a frightening amount of the field.

Final thought

A bad PIC can look small on paper and do enormous damage in real life. That is the practical lesson. Do not treat the PIC as a label. Treat it as the hinge. Because once the hinge is bent, every other door in the case starts sticking too.

What is a PIC?

If you are dealing with medical discharge, armed forces pensions, compensation schemes, or a growing and unhealthy interest in military paperwork, you will eventually meet the phrase Primary Invaliding Condition, or PIC. At first glance, it sounds like exactly the sort of official jargon designed to make ordinary people feel faintly stupid. It is jargon, certainly, but it is important jargon. In practice, the PIC is often the official medical condition the system says brought about your medical discharge or invaliding. Once that condition is written down, all sorts of things can begin to flow from it: pension decisions, compensation decisions, tax consequences, review rights, appeal arguments, and long-running disputes over whether everyone is even talking about the same medical problem.

So if there is one thing to take from this section, it is this: the PIC is not just a label. It is often the starting point for the whole legal and financial story.

In short, a PIC is the main condition recorded as causing your medical discharge or invaliding. If a person has several health problems, the PIC is meant to identify the one treated as the principal, career-ending condition. It is, in effect, the system’s answer to the question: what is the condition that actually broke military service? That does not mean it is always the only condition the person has, or even necessarily the condition that occupies the most space in their medical records. It means it is the condition being given top billing in the paperwork. And in this area, top billing matters.

The PIC is usually recorded on the medical board paperwork, especially the FMed 23. That is important because the PIC is not supposed to be something invented later in a pensions office after a heroic amount of administrative guesswork. It starts in the medical process itself. The paperwork records the principal condition affecting the medical employment standard, other relevant medical conditions, the date of origin, the place of origin, and the board’s findings about medical grading and employability. MOD guidance recognises that the principal condition needs to be recorded carefully because it may directly affect later decisions on armed forces pensions, war pensions, and AFCS compensation. That is a polite bureaucratic way of saying that if this bit is wrong, the rest of the case may wobble from the start.

The reason the PIC matters so much is that it sits at the point where the medical story turns into the legal and financial story. Andrew Bano’s textbook is especially helpful here, because it shows that these schemes are not really organised around labels alone. They are organised around a series of distinct legal questions: what is the disablement, what is the injury or pathological process causing it, and is that injury attributable to service? Those are not the same question. A PIC may look like a simple diagnosis, but in practice it often acts as the system’s shorthand for all three. That is where trouble begins, because a vague or flattened label can blur the distinction between the symptoms a person suffers, the underlying condition causing them, and the legal question of whether service caused or worsened that condition.

So, is a PIC just a diagnosis? Not really. Yes, it is a diagnosis or medical condition in one sense. But in practical terms it is doing several jobs at once. It is a medical statement, because it identifies the condition said to have led to invaliding or medical discharge. It is an administrative statement, because it tells the system which condition to treat as the principal problem for pension and compensation purposes. And it is often a legal and financial trigger, because it may affect which pension rules are engaged, which compensation scheme applies, whether a pension later becomes tax-free, whether a review can move someone to a better outcome, and what exactly gets argued about if the case reaches a tribunal. So while the PIC looks like a clinical label, it often functions as the hinge between the medical story and the money story.

That is also why the PIC is not simply “whatever diagnosis appears somewhere in the records.” Bano’s analysis is valuable because it reminds readers that legal systems care about disablement in a functional sense, not just diagnosis in a classificatory sense. A person may have a condition labelled “back pain,” but the real legal and financial significance may lie in a service-related spinal injury that has destroyed their functional ability to march, lift, deploy, sit, drive, or sustain work. Likewise, “low mood,” “anxiety symptoms,” or “functional complaints” may all be medically possible phrases, but they do not necessarily tell the legal truth about what ended service. One of the recurring themes in this field is that the chosen wording can drain a condition of its service context, severity, and practical consequences before any later appeal even begins.

Why not simply list every condition and avoid the whole problem? It is a fair question, particularly because many medically discharged people have several serious conditions. Sometimes one leads to another. Sometimes they overlap. Sometimes the thing that ends service is not the single worst condition overall, but the one that made military employment impossible first. The guidance generally expects one condition to be treated as principal, with other relevant conditions listed separately, and only in exceptional cases more than one condition will be treated as principal. That makes administrative sense, because the system wants one lead condition. Unfortunately, human bodies do not always cooperate with that plan. One of the recurring problems in PIC disputes is that the wrong condition gets given top billing, or the principal condition is described too vaguely, or the more service-related condition is demoted into the “other conditions” section, or the recorded PIC fails to capture the true seriousness of what was happening. Once that happens, later decision-makers may begin from the wrong map.

The PIC is not always the objectively “worst” condition either. It is meant to be the condition leading to invaliding or medical discharge. That may be the worst condition, the most service-relevant condition, the most functionally disabling condition, or simply the condition the board believed to be decisive for service purposes. Sometimes those all point in the same direction. Sometimes they do not. A person may have several chronic problems, but one spinal injury is what actually ends their service. Another may have a long musculoskeletal history, but the decisive discharge driver is a mental health condition. Someone else may have multiple serious diagnoses, but only one is treated as the main employment-ending problem. That is why a PIC argument is often not “this other condition exists,” but rather “this other condition should have been recognised as the principal one.”

The PIC matters across all of the pension and compensation schemes, but it does different work in different legal settings. Under AFPS 1975, the PIC matters because the system is still heavily shaped by invaliding, attributability, service causation, and the consequences of whether the discharge-causing condition was related to service. In that world, the PIC can operate like a master key. Under AFPS 2005, the PIC still identifies the discharge-causing condition, but it also becomes central to the tiering exercise, because the question is no longer just whether service has ended but how the condition affects future gainful employment. Under AFPS 2015, the PIC still drives medical discharge and ill-health pension questions, but it sits inside a CARE structure, transitional protections, and a more layered review framework. On the compensation side, the PIC may help connect the discharge condition, the causation story, the date and place of origin, and the later claim under WPS or AFCS. So yes, the PIC matters everywhere, but not in exactly the same way.

Does the PIC decide what compensation scheme applies? Not by itself. The main dividing line between WPS and AFCS remains the date when the injury, illness, or death was caused by service: before 6 April 2005 usually points toward WPS; on or after 6 April 2005 usually points toward AFCS. But the PIC still matters because it helps identify what the relevant condition is, when it began, where it began, whether the condition now being claimed is really the same condition that caused discharge, and whether the discharge and compensation systems are even talking about the same thing. In other words, the PIC does not replace the date test. It helps make the date test usable.

Bano’s treatment of WPS and AFCS helps explain why all this matters so much. Under WPS, the concepts of injury, disablement, and service attribution have their own structure, and in the right kind of case the burden may shift heavily onto the Secretary of State once a credible case has been raised. Under AFCS, the causation analysis is more structured and often less forgiving, with the authorities drawing careful distinctions between relevant causes and, in some contexts, whether service was the predominant cause. A weak or generic PIC can therefore do damage in both schemes, but for slightly different reasons. Under WPS it may obscure the condition whose attribution is being considered; under AFCS it may distort the later analysis of what exactly the service-related condition was and how it should be classified.

This is also why people argue about the PIC so fiercely. Once the PIC is written down, it can be very difficult to escape it. If the PIC is too vague, too mild, wrongly chosen, or badly described, later decisions may all start from the wrong place. That can affect tiering, attributable status, compensation scheme interaction, tax treatment, and appeal routes. “Service-related traumatic spinal injury” and “back pain” do not create the same administrative weather. One points towards a serious, service-linked disabling event. The other sounds like something the department hopes will go away quietly. People do not argue about the PIC because they enjoy semantics. They argue because in this field, wording often becomes money.

The PIC can also matter for tax. One recurring issue across the armed forces pension schemes is whether a later WPS or AFCS award relates to the same condition that caused the discharge. If it does, that may affect whether the pension is treated as tax-free. This is where Bano’s discussion of “same condition” issues is especially helpful. A later, better diagnosis does not automatically create a new condition. Sometimes it simply reveals what the condition always was. So if the discharge paperwork says one thing and the compensation award later uses slightly different wording, the veteran can end up in a faintly absurd dispute about whether the same broken body part is really the same broken body part. That is why precise medical wording matters. It is not pedantry. It is the chain of legal consequences being protected.

The PIC also sits silently at the centre of many appeals. People may think they are appealing a pension tier, a compensation descriptor, a WPS disablement assessment, or a tax decision. But underneath, the real problem is often that the wrong condition was chosen as principal, the right condition was described too blandly, the medical summary understated the disablement, or the system quietly substituted a tidier label for the actual medical reality. The appeal then becomes a fight about consequences, but the root problem is still the original wording.

Can the PIC be changed? Potentially, yes. There are routes under service policy to challenge the PIC code itself, including under AGAI 78. But earlier review against Bano highlighted the need for caution here. Deadlines and route details should not be stated more rigidly than the underlying policy supports, and anyone relying on a particular window should check the current rule and the exact facts of their case. The practical point remains the same, though: if the PIC is wrong, it is much better to spot it early than to spend years arguing about its downstream effects.

One of the nastiest variants is where the PIC is not wholly false, but still misleading. Sometimes the problem is not that the label is impossible. It is that it is incomplete, over-generic, clinically tidy, or narratively weak. It may use medically defensible words while quietly failing to reflect service causation, severity, function, or the real reason the career ended. That can still cause serious downstream damage. So when checking a PIC, the question is not only whether the diagnosis is technically possible. It is whether the wording tells the truth about what ended service. Those are not always the same thing.

A simple practical test is to ask the following. Is it the right condition? Is it the most important condition? Does it reflect what actually ended service? Does it match the later pension paperwork? Does it match the compensation paperwork? Does it reflect the real functional impact? Does it preserve the service-related story, if service causation matters? Would someone reading it years later actually understand what happened? If several of those answers are “no” or “not really,” the PIC may be a live issue.

So the short version of the short version is this: a PIC is the principal medical condition the system says caused your invaliding or medical discharge. It matters because it can shape pensions, compensation, tax, reviews, appeals, and years of later argument. Or to put it another way, it is the line on the form that the whole rest of the file keeps coming back to, which is exactly why it needs to be right.

AFPS 2005: where the PIC starts grading your future

If AFPS 1975 was the era of invaliding, attributability, and arguments about whether service caused the condition that ended the career, AFPS 2005 represents a shift in emphasis. The pension scheme and the compensation scheme become more clearly separated. The old-style attributable pension model gives way to a structure in which the pension side is focused much more on future employability, while the compensation side sits under AFCS for post-6 April 2005 service-caused injury or illness. That does not make the system simpler. It just means the PIC begins to do a slightly different kind of work.

Under AFPS 2005, the Primary Invaliding Condition is still the condition said to have brought military service to an end. But it is no longer important only because it identifies what invalided you. It also matters because the scheme uses that condition, and more importantly its consequences, to assess what sort of working future the member is thought to have outside the armed forces. In that sense, AFPS 05 is less interested than AFPS 75 in the old question “was this attributable?” for pension purposes, and more interested in the question “what does this condition do to your capacity for gainful employment?”

That shift explains why AFPS 05 introduced the three-tier ill-health structure. The scheme was designed in part to move away from the older model under which people with very different levels of post-service impairment could receive broadly similar pension outcomes because rank and service length did most of the work. AFPS 05 tries, at least in theory, to tie pension outcomes more closely to the real effect of the condition on the person’s ability to earn a living after discharge. That means the PIC changes job description. It is still the condition that ended service, but it also becomes the anchor for the decision about how far the condition is said to damage future employability.

As with AFPS 75, the PIC does not begin life in a pensions office. It starts on the medical board paperwork. The MOD’s medical guidance makes clear that the principal condition affecting the medical employment standard should be recorded carefully because it may directly affect later armed forces pension and AFCS decisions. Normally only one principal condition should be listed, unless there is a proper reason to identify more than one. The board should also record the date and place of origin of the condition, and if the relevant event occurred on operations, that should be recorded too. All of that matters because if the wrong condition is given top billing at board stage, the pension decision built on it may already be skewed before Veterans UK gets involved.

This is also where Bano’s analysis is useful at a conceptual level. One of the clearest points in his treatment of war pensions and AFCS is that legal schemes in this area do not simply ask one question. They distinguish between disablement, the injury or pathological process causing that disablement, and the legal question of service causation. AFPS 05 is a pension scheme rather than a compensation code, but the same warning applies. A PIC may look like a neat diagnosis, but if it is vague or flattened it can conceal the real severity of the disablement and the actual process causing it. That matters because tier decisions are not supposed to be made on the basis of a tidy label alone. They are supposed to engage with what the condition actually does.

AFPS 2005 introduced three tiers of ill-health award. Tier 1 applies where the member is unfit for continued service, but their capacity for gainful civilian employment is not regarded as significantly impaired. Tier 2 applies where civilian earning capacity is significantly impaired. Tier 3 applies where the member is permanently incapable of any gainful full-time employment. Those are the headline categories, but the important thing for present purposes is that the PIC sits in the middle of all three. The condition identified as the PIC is not just the reason for discharge. It is the condition whose functional and vocational consequences are being assessed to place the member in one of those tiers.

That is why the PIC matters so much under AFPS 05. If the condition is described too mildly, too vaguely, or in a way that strips out the practical reality, the member may be funnelled toward Tier 1 far too readily. A neat diagnostic phrase can make a wrecked working life look oddly manageable on paper. The more generic the PIC, the easier it can become for the decision-maker to drift into broad assertions about civilian employability without really grappling with what the evidence shows. A person may be unfit to deploy, unable to sit for long, unable to stand for long, unable to drive safely, unable to perform safety-critical work, unable to concentrate reliably, or unable to tolerate stress or sustained attendance, and yet the paperwork may still present the PIC in language that sounds almost trivial. Once that happens, the tiering exercise is already in danger of floating away from reality.

Tier 1 is the point at which the scheme accepts that the member cannot continue in service but does not accept that civilian employability is significantly impaired. That is often where under-described PICs do their worst damage. If the wording of the PIC is bland and the functional consequences are not spelt out, the scheme can move far too quickly to the idea that the member is still employable in civilian life in some unspecified role. This is one of the places where the legal and evidential discipline described by Bano is helpful by analogy. Decision-makers cannot simply assert a conclusion and leave the bridge to the evidence unbuilt. If the conclusion is that the person’s earning capacity is not significantly impaired, there ought to be a reasoned route from the medical facts to that conclusion. A label alone will not do the job.

Tier 2 is where many of the most serious AFPS 05 disputes arise. The question is whether the member’s capacity for gainful employment is significantly impaired. That means the PIC has to do more than explain why the member left the armed forces. It has to be analysed for what it does to the member’s ability to obtain and sustain realistic civilian work. That is not meant to be a purely abstract exercise. One of the general lessons reinforced by modern case law, and reflected in Bano’s discussion of tribunal reasoning, is that categorisation requires reasons and reasons require a proper factual baseline. In AFPS 05 terms, that means the decision-maker should ask what this person, with this background, this experience, and this medical evidence, can realistically do in the labour market. It is not enough to invoke the magical possibility of “desk work” without examining whether the evidence actually supports that as a real option.

Tier 3 takes the argument one step further. Here the question is whether the person is permanently incapable of any gainful full-time employment. Again, the danger of a weak PIC is obvious. If the condition is described in generic or watered-down terms, the seriousness of the disablement can be hidden at the very moment when the scheme is deciding whether the member has effectively been removed from the full-time labour market altogether. Tier 3 outcomes are correspondingly more generous, which is one reason they are hard-fought and heavily evidence-dependent. The PIC does not decide Tier 3 by itself, but it often sets the tone for the whole exercise. If the condition has already been administratively shrunk at the medical board stage, the later argument starts from a distorted premise.

One of the most useful legal ideas in this area is the baseline question: employable as what, exactly? Although the detailed authorities Bano discusses are often compensation cases rather than AFPS 05 pension cases, the underlying insistence on proper reasoning is directly relevant. A decision-maker who says that a person remains capable of gainful employment needs to engage with the actual baseline. Is this a person with transferable civilian qualifications, a patchy work history outside service, severe restrictions on sitting, standing, lifting, travel, concentration, social interaction, or stress tolerance? Or is the decision-maker simply imagining an abstract labour market in which “civilian work” means some benign desk-based role that no real employer is obliged to provide? AFPS 05 cases often turn on that gap between abstraction and reality.

This is also where the medical board system and the pension system are really having the same conversation. The medical process asks what the condition does to deployability, general duties, trade duties, restrictions, and functional capacity. The pension process asks what the condition does to gainful employment. Those are not identical questions, but they are closely related. A condition that leads to restrictions such as office duties only, no prolonged sitting, no prolonged standing, no driving, no strenuous activity, no operational work, or significant psychiatric instability ought to feed directly into a serious analysis of civilian work capacity. If the PIC sounds mild but the restrictions are severe, that mismatch is itself evidentially important.

Bano’s discussion of causation also matters here, even though AFPS 05 pension tiering is not itself the same thing as an AFCS compensation decision. Under AFCS, the legal analysis is more structured and, as Bano emphasises, depends on identifying relevant causes, disregarding causes that are too remote, separating service-related and non-service-related causes, and deciding whether service was the predominant cause. That is a more technical and sometimes less generous framework than WPS. The practical relevance to AFPS 05 is that many members are dealing with pension and compensation issues at the same time. The PIC may therefore sit across both worlds. A vague PIC can make the pension case look weaker and the AFCS case harder to frame. Conversely, a later AFCS award may depend on a more precise medical description than the one used at discharge. That is where “same condition” disputes begin to emerge.

The “same condition” issue is particularly important under AFPS 05 because a later AFCS award for the same injury may affect tax treatment and the interaction between pension and compensation. Bano is especially helpful here. A later, more precise diagnosis does not automatically create a new condition. Sometimes it simply reveals what the condition always was. That matters where the discharge paperwork used vague or generic language and the later AFCS award uses a more clinically accurate description. If the pension side then tries to say these are not the same condition, the right question is often whether the later description is simply the first proper naming of the same underlying disablement. That can matter not just conceptually but financially.

It matters financially because of the way AFPS 05 interacts with AFCS awards and Guaranteed Income Payment. If an AFCS award is made for the same condition that caused the medical discharge, the pension can become tax-free. That makes the “same condition” issue immediately significant. At the same time, the interaction with GIP can be awkward. Where an ill-health pension is being paid for the same injury, the GIP calculation takes account of that income. So a successful challenge to tiering may not always produce the intuitively expected net benefit in hand, even though the legal outcome is still important. The article should preserve that practical warning, but it should do so carefully and in a way that distinguishes scheme mechanics from broad principle.

AFPS 05 also has an important review dimension. One of the more useful features of the scheme is that it recognises that health can deteriorate after discharge. There are routes for review, and the distinction between an original decision being wrong and a condition later worsening can have important consequences for backdating and outcome. Bano’s analysis of review and fresh claim issues is relevant by analogy here as well. A later claim is not always a genuinely new medical case. Sometimes it reflects that the original condition was misdescribed, underestimated, or misunderstood from the outset. In plain terms, if the original PIC and tier decision were built on an unrealistically mild description of the condition, the later review may not be revealing a brand-new problem at all. It may simply be exposing that the original decision was wrong.

The same is true of mistakes of fact. Earlier review of your long draft rightly identified that this concept needs legal precision. It should not be used as a loose phrase meaning “they got it wrong.” But the core idea remains valuable. A decision resting on a materially mistaken factual understanding of the medical position may be challengeable in a more fundamental way than simple disagreement over weight. That is important in AFPS 05 cases because tiering decisions are highly sensitive to factual assumptions about function, prognosis, restrictions, and realistic employability. If those assumptions are wrong, the entire structure of the decision may wobble.

The AFPS 05 section should also keep the point that this is not an attributable pension scheme in the AFPS 75 sense. For conditions caused on or after 6 April 2005, the attributable compensation route sits under AFCS. For conditions caused before that date, transitional and hybrid issues can arise, including interactions with earlier rights. This is one of the reasons AFPS 05 cases can become so complex. The pension scheme looks modern, but many members have service histories or conditions that straddle older rules. The PIC becomes especially important in those overlap situations because it may be the only thing trying to hold together a story that spans more than one legal regime.

There is also still value in mentioning the Offer to Transfer from AFPS 75, because it explains why some members under AFPS 05 arrive there with complicated protected rights or hybrid histories. But that point should remain subordinate to the main theme: the significance of the PIC. The core legal story is not the transfer choice itself. It is that a person’s discharge condition may sit within AFPS 05 for pension purposes while compensation, tax treatment, and same-condition arguments still require close attention to pre-2005 and post-2005 distinctions.

As for challenging the PIC itself, the cautious approach taken in the earlier review should be preserved here too. There may be routes under AGAI 78 and associated policy to challenge the PIC code or description, but deadlines and route details should be checked against the current policy rather than asserted too absolutely. The practical advice remains simple and sound: if the wrong condition has been selected as principal, or the right condition has been described so vaguely that it drains away the seriousness of the case, that issue should be raised early and clearly.

The bottom line is that AFPS 2005 is the scheme in which the PIC becomes the hinge between medical discharge and future employability. AFPS 75 asked, in broad terms, whether the invaliding condition was attributable to service. AFPS 05 asks what the discharge condition does to the person’s ability to earn a living afterwards. That makes the PIC more than a diagnosis and more than an administrative code. It becomes, in effect, the official starting theory of what sort of worker the member is still thought to be.

That is a great deal of power to hand to a few words on a form. Which is why those words need to be accurate, specific, and grounded in the real medical evidence. If they are not, the rest of the AFPS 05 analysis — tier, review, tax, compensation interaction, and all — may start from the wrong premise.

AFPS 2015: where the PIC enters the CARE era

AFPS 2015 did not make the Primary Invaliding Condition any less important. If anything, it gave it more work to do. Under the earlier schemes, the PIC was already doing a great deal: identifying the condition that ended service, shaping ill-health pension outcomes, and influencing the interaction with compensation. Under AFPS 2015, all of that remains true, but it now sits inside a pension structure built around career-average earnings, layered on top of legacy rights, transitional protection, review powers, and continuing interaction with AFCS. The result is that the PIC has to operate not just as a medical label and not just as a pension trigger, but as the hinge point between several overlapping legal and administrative systems.

One of the first things to say, and one that matters a great deal in practice, is that AFPS 2015 was not a clean break with the past. It did not wipe away AFPS 75 and AFPS 05 and start again on an empty page. As the governing materials make clear, accrued legacy rights remained protected. Where service continued across the transition, those legacy benefits retained their own rules and, crucially, their final salary link. That means a member may be discharged in the AFPS 2015 era because of a PIC recorded on modern paperwork, while the financial effect of that discharge still feeds directly into older AFPS 75 or AFPS 05 rights. For many people, then, an “AFPS 2015 case” is not really a pure AFPS 2015 case at all. It is a hybrid case in which a modern ill-health decision interacts with older protected entitlements.

That point is important because it changes how the PIC should be understood. The PIC is still the official condition said to have brought about discharge, but under AFPS 2015 it may now help determine not only the person’s current ill-health award under a CARE structure, but also the point at which protected legacy rights crystallise, the value of those rights through the final salary link, and the later interaction between pension and compensation. So even where the section is headed “AFPS 2015”, the legal consequences of the PIC may spread backwards into older pension worlds.

As with the earlier schemes, the PIC begins life on the medical board paperwork, not in the pensions office. The FMed 23 remains central. The governing medical materials make clear that the principal condition affecting the medical employment standard must be identified carefully because it may directly affect later pension and compensation outcomes. Ordinarily one principal condition should be recorded, with multiple principal conditions reserved for unusual cases in which more than one has an equal effect. The same guidance requires the narrative to address function, restrictions, and the effect of the condition on employment standards. That is not a decorative requirement. It reflects the practical truth that the PIC is not supposed to be just a diagnosis in isolation. It is supposed to connect the medical facts to the employment consequences and then, downstream, to the pension consequences.

That point sits comfortably with Bano’s broader analysis. One of the most useful features of his treatment of war pensions and AFCS is the insistence that these legal schemes do not revolve around diagnosis labels alone. They involve distinct questions: what is the disablement, what injury or pathological process causes it, and what is the legal relationship between that injury and service? AFPS 2015 is not the same as WPS or AFCS, but the warning still applies. A neat diagnostic phrase may conceal a much more serious disablement. A generic label may fail to capture the actual pathological process. A bland descriptor may strip out the service narrative that later matters for AFCS or tax treatment. So although AFPS 2015 is an ill-health pension scheme rather than a compensation code, it still requires the same caution about labels. The PIC is often doing far more than naming a condition. It is summarising, for administrative purposes, the condition that the whole rest of the system will keep returning to.

Like AFPS 2005, AFPS 2015 uses a three-tier ill-health structure. The broad categories are familiar: Tier 1 where the person is unfit for service but civilian gainful employment is not significantly impaired; Tier 2 where capacity for gainful employment is significantly impaired; and Tier 3 where there is permanent incapacity for any gainful full-time employment. The difference lies not in the categories themselves but in the pension engine behind them. AFPS 2015 is a CARE scheme. That means the underlying pension architecture is different, but the practical role of the PIC within the ill-health decision remains strikingly similar to AFPS 05. It is the identified condition whose effects are being assessed to decide which tier applies.

That is exactly why Upper Tribunal case law, although often arising in AFCS rather than AFPS 2015, is still so helpful by analogy. One of the strongest themes in the authorities discussed by Bano is that legal categories are not self-proving. A tribunal or decision-maker cannot simply say that a claimant falls into one box rather than another and leave the reasoning unstated. That is highly relevant to AFPS 2015 tier decisions. If the department says the PIC justifies Tier 1 rather than Tier 2, or Tier 2 rather than Tier 3, that conclusion needs a real evidential and analytical basis. It is not enough to rely on the abstract phrase “gainful employment” without identifying what work is realistically in view, how the person’s actual restrictions bear on that work, and why the evidence supports the conclusion reached.

This brings us to one of the most useful legal ideas in this field: the baseline question. Compared with what sort of work is the person said to remain employable? Bano’s discussion of modern tribunal reasoning in compensation cases repeatedly illustrates the importance of identifying the right baseline before deciding whether a category is met. That translates directly into AFPS 2015. If the question is whether capacity for gainful employment is significantly impaired, there must be some realistic baseline of employment against which that judgment is made. Is the decision-maker talking about work suited to the member’s actual education, training, rank, service experience, and restrictions? Or is the analysis drifting into a fictional labour market full of unspecified desk jobs that no real employer is obliged to provide? A proper AFPS 2015 analysis should stay tied to reality.

That is especially important because AFPS 2015, like the medical grading system that feeds into it, is supposed to care about function. The medical guidance is explicit that service medical assessment is concerned with functional capacity, general duties, trade duties, and deployability. Restrictions and medical limitations codes are designed to record what the person can and cannot actually do. If the PIC says “lumbar disc injury” or “depressive disorder” but the restrictions show inability to sit for long periods, inability to stand for long periods, inability to drive safely, inability to undertake strenuous activity, inability to deploy, inability to tolerate stress, or office duties only, then the real evidential story lies in the function, not just the diagnosis. The same applies to hearing loss, neurological conditions, chronic fatigue, or complex pain cases. A tidy diagnosis can make the person look much more employable on paper than they are in lived reality.

This is one of the places where AFPS 2015 can go wrong in a way Bano’s analysis helps to expose. A condition may be medically recognised, but the disablement may be understated. The label may be technically defensible, but the functional consequences may be administratively flattened. The reasoning may jump too quickly from “unfit for service” to “still fit for civilian work” without building the bridge in between. That is not just frustrating; it may be challengeable. One of the repeated lessons of the case law is that reasons matter. Decision-makers must explain themselves. If a member’s restrictions are severe but the scheme concludes that gainful employment is not significantly impaired, the explanation for that conclusion ought to be visible.

AFPS 2015 also has to be read alongside AFCS, because for post-6 April 2005 service-caused conditions the compensation route sits there. This is another reason why Bano remains useful even in a pension section. His treatment of AFCS causation is particularly important. Under AFCS, as he explains, the question is not simply whether service played some role. The legal inquiry asks what the relevant causes were, which can be disregarded as too remote, which of the remaining causes were service-related and which were not, and whether service was the predominant cause. That is a more structured and often less generous causation framework than WPS. For AFPS 2015 purposes, the practical relevance is that the same PIC may sit across both schemes. A vague or flattened PIC may create difficulties not just for tiering but also for framing the AFCS case properly. Equally, a later AFCS award may use a more accurate diagnosis than the one recorded at discharge. That is where “same condition” disputes begin.

The “same condition” point matters under AFPS 2015 for several reasons. It may affect whether the pension and compensation decisions are treated as legally connected, whether an AFCS award is recognised as relating to the same injury that caused the medical discharge, how tax treatment operates, and how GIP interacts with the pension. Bano is very helpful here because he emphasises that a later diagnosis does not necessarily create a new condition. Sometimes it is simply a more accurate description of the same underlying injury or disablement. That is exactly the sort of issue that arises where the FMed 23 uses a vague symptom label and the later AFCS decision uses a proper diagnosis. If the state then tries to say they are different conditions, the legally sensible question is whether the second label is just the first accurate description of the same damaged human being.

This is particularly important in relation to GIP and tax treatment. If an AFCS award is made for the same condition that caused the medical discharge, the financial interaction with the AFPS 2015 pension can be significant. The pension may become tax-free in the relevant circumstances, but the GIP calculation may also take the pension into account where both relate to the same injury. So the “same condition” argument is not merely semantic. It can affect what the member actually receives. That is why the PIC remains so central. It is often the first formal statement of which condition the system thinks ended service, and later schemes keep trying to read back from that sentence.

AFPS 2015 also has review powers, and these deserve careful treatment. The public-facing explanation is often framed in claimant-friendly terms: if the condition deteriorates unexpectedly within five years of discharge, the member may ask for a review. But the underlying rules are more structured than that, and the review power can cut both ways. The scheme manager may review certain awards if it appears that the condition has changed. As with AFPS 05, it matters whether the argument is that the original decision was wrong at the time or that the condition genuinely worsened later. Bano’s discussion of fresh claims, reviews, and later better diagnoses is very relevant here. Not every later application is truly a new medical case. Sometimes the problem is that the original condition was misdescribed, underestimated, or misunderstood from the outset. In those cases the legal character of the later challenge may be different from a pure deterioration claim.

This is also where caution about “mistake of fact” remains important. Earlier review of your long draft correctly noted that this doctrine needs precision. It should not be used casually to mean “the decision was wrong.” But the core point remains useful: if the decision was made on a materially false factual basis about the condition, the restrictions, the chronology, or the prognosis, that may have serious legal consequences. AFPS 2015 tier decisions are particularly vulnerable to factual distortion because they depend so heavily on an accurate understanding of function and realistic employability.

The transitional protection material also matters in a way that should be preserved in the revised section. Some members remained in their legacy schemes under protection; others moved into AFPS 2015 while keeping accrued legacy rights. That means AFPS 2015 PIC cases often fall into three broad groups: genuinely pure AFPS 2015 cases, hybrid cases with both legacy and 2015 rights, and effectively legacy cases with no real AFPS 2015 exposure for the relevant period. The article should continue to say that plainly, because one of the easiest mistakes in this area is to treat all post-2015 discharges as if they belonged to one neat legal world. They do not.

There is also practical value in keeping the point about challenging the PIC itself, but with the same caution as before. There may be policy routes under AGAI 78 and associated materials for challenging the PIC code or underlying medical board recording. Earlier review suggested the article should not state time limits too baldly without checking current policy and any possible exceptions. That remains the safer approach. The practical message can still be firm: if the wrong principal condition has been recorded, or the narrative strips out the real functional seriousness of the case, the issue should be identified and raised early, because the wording will travel beyond the medical board into the pension and compensation systems.

Finally, AFPS 2015 disputes about the pension consequences of the PIC can be taken through the scheme’s internal dispute route. That matters because not every PIC problem is really a medical coding problem. Sometimes the PIC itself is accepted, but the scheme manager has drawn the wrong pension conclusion from it. Sometimes the issue is tiering. Sometimes it is review. Sometimes it is the interaction with AFCS, GIP, or protected legacy rights. Bano’s broader lesson is helpful here: the field is full of legal traps, and the trap often lies not in the headline diagnosis but in the legal characterisation and reasoning built on top of it## AFPS 2015: where the PIC enters the CARE era and somehow gets even more to do

If AFPS 1975 is a brass telescope and AFPS 2005 is an Excel spreadsheet with anger issues, AFPS 2015 is the scheme where the MOD embraced the modern age, introduced career-average pensions, added transitional protections, and somehow made the Primary Invaliding Condition even more important than it already was. This is the scheme where the PIC is not just the condition that gets you medically discharged and not just the condition that helps place you in a tier. It is also the condition that has to survive contact with a CARE pension structure, legacy rights from AFPS 75 or AFPS 05, transitional protection rules, review powers, tax questions, AFCS interaction, and the increasingly familiar problem of one part of the state not quite agreeing with another part of the state about what has happened to your body.

AFPS 2015 is modern in the same way airports are modern: shiny at first glance, then full of queues, rules, and signs pointing in six directions at once.

AFPS 2015 is not a clean break

One of the biggest misconceptions about AFPS 2015 is that it swept away the past and started afresh on 1 April 2015. It did not. The legislation and policy material are clear that AFPS 2015 sits on top of a large pile of legacy rights. If you were already serving before 1 April 2015, what you had earned under AFPS 75 or AFPS 05 did not simply evaporate. Those accrued rights were protected, and where continuous service was maintained, legacy benefits stayed linked to your final rank and salary at the point of leaving service, not the point of transfer. JSP 905 spells this out. Where continuous service is maintained between legacy schemes and AFPS 15, the old pension is still calculated according to service in the legacy scheme, but it uses the final salary or rank achieved at the end of military service, including service within AFPS 15.

That sounds dry, but for PIC purposes it matters enormously. The same discharge-causing condition may end service during AFPS 2015 membership while still affecting the practical value of older AFPS 75 or AFPS 05 rights. So before asking what AFPS 2015 says about a particular PIC, the prior question is often whether this is a pure AFPS 2015 case at all, or one of those classic military half-old, half-new, all-headache hybrid cases. In practice, the answer is often the second one.

The PIC is still born on the FMed 23

Before pensions administrators, scheme managers, or tribunals start arguing about the future, the PIC begins life in a medical board document. AGAI 78 and JSP 950 both matter here. The FMed 23 asks for the principal condition or conditions affecting the medical employment standard leading to the fitness for work assessment. JSP 950 says this box should be completed with care because it may have a direct impact on the later award of an armed forces pension or compensation under AFCS. It also says it should normally list only one condition, with more than one listed only in exceptional cases where more than one condition has an equal effect on the medical employment standard.

AGAI 78 adds important detail. Only the conditions actually driving the lowered medical grading should be listed as principal. The FMed 23 narrative must assess functional capacity, identify employment restrictions, comment on risk, and interpret the findings against the relevant medical employment standards. So under AFPS 2015, the PIC is not supposed to be a decorative phrase. It is supposed to be the key condition that explains the lowered JMES, explains the discharge, and later feeds into the pension and compensation consequences. If that condition is wrongly chosen, or described in language that strips out the real functional picture, much of what follows may be built on the wrong foundation.

Bano's analysis is useful here at a conceptual level. His treatment of war pensions and AFCS emphasises that legal schemes in this area do not simply ask one question. They distinguish between disablement as a concept, the injury or pathological process causing that disablement, and the legal question of service causation. Although AFPS 2015 is a pension scheme rather than a compensation code, the same warning applies. A PIC may look like a neat diagnosis, but if it is vague or flattened it can conceal the real severity of the disablement and the actual process causing it. That matters because tier decisions are not supposed to be made on the basis of a tidy label alone. They are supposed to engage with what the condition actually does.

AFPS 2015: same three tiers, different pension engine

Like AFPS 2005, AFPS 2015 uses a three-tier ill-health structure. Tier 1 applies where the member is unfit for continued service but civilian gainful employment is not regarded as significantly impaired. Tier 2 applies where civilian earning capacity is significantly impaired. Tier 3 applies where the member is permanently incapable of any gainful full-time employment. But AFPS 2015 calculates benefits using a CARE structure, meaning career average revalued earnings, rather than the final salary model used under AFPS 05. The PIC is therefore being dropped into a different pension machine. The condition still drives the ill-health route, but the money is built up differently, and the interaction with legacy rights adds further complexity for those with service spanning more than one scheme.

The legal cases say: categories are not self-proving

This is where the Upper Tribunal case law becomes directly relevant. One of the clearest themes running through the modern cases is that saying a claimant fits a category is not the same as proving they fit a category. In DA-B v Secretary of State for Defence [2025] UKUT 290 (AAC), the Upper Tribunal found that the First-tier Tribunal had failed to provide an adequate comparative evaluation of why the claimant fit one descriptor rather than another, and had also failed to identify the right baseline of work appropriate to the claimant's qualifications, experience, and skills before comparing that with what the claimant could do afterwards. Although that case concerned AFCS descriptor selection, the principle translates directly into AFPS 2015 tier disputes. Tier 1, Tier 2, and Tier 3 are all essentially category decisions. If the decision-maker says the PIC only supports Tier 1 rather than Tier 2, or Tier 2 rather than Tier 3, it is not enough to intone the words "gainful employment" in an official voice. The decision needs to show how the evidence supports that outcome.

Bano's analysis reinforces this. His discussion of the legal framework for war pensions and AFCS repeatedly emphasises that decision-makers must engage with the actual disablement, not just the label. The same discipline applies here. A tier decision that rests on a generic description of the PIC, without engaging with the functional consequences, the realistic employment baseline, or the actual medical evidence, may be legally vulnerable even if it sounds authoritative.

The baseline problem: compared to what sort of work, exactly?

The baseline point deserves particular attention because it is one of the most practically useful ideas from the case law. Under AFPS 2015, the question is often whether capacity for gainful employment is significantly impaired, or whether the member is incapable of any gainful full-time employment. That sounds straightforward until the next question arrives: compared with what? Compared with any theoretical job in Britain? A desk job that exists only in MOD imagination? Work that fits the member's actual education, training, and service background? Work they can realistically sustain given their symptoms, fatigue, pain, mental state, and restrictions?

The recent cases suggest that tribunals must identify the right factual baseline before deciding these questions. That is very helpful in PIC cases. If the MOD says the PIC leaves the member fit for some vaguely civilian future, it should not be allowed to leave that future entirely undescribed. A person with a service background in a physically demanding trade, severe restrictions on sitting, standing, lifting, and concentration, and significant mental health symptoms is not the same as a person who can walk into a sedentary civilian role on Monday morning. The law keeps nudging the analysis back toward reality, which is bad news for lazy decision-making and good news for members whose PIC has been understated.

The law also requires reasons

A second strong theme across the Upper Tribunal material is that decision-makers must give adequate reasons. That comes through not only in DA-B, but also in cases such as CRP v Secretary of State for Defence [2025] UKUT 140 (AAC) and MJU v Secretary of State for Defence [2025] UKUT 033 (AAC). Different facts, same broad complaint: tribunals and decision-makers cannot simply announce a conclusion and expect everyone to accept it. That matters to AFPS 2015 PIC cases because these cases often turn on fine distinctions. Is this military unfitness or significant civilian impairment? Is this significant impairment or total incapacity? Was the claimant misdiagnosed at the outset, or has the condition deteriorated since? Is the key problem the principal condition, or a combination of conditions that the original paperwork never captured properly? Where the answer turns on those distinctions, reasons matter. If the scheme manager or tribunal says the PIC only justifies Tier 1, it needs to show how it got there. If it does not, the member may have more than just a bad feeling. They may have a proper appeal point.

Causation is more subtle than the MOD likes to admit

AFPS 2015 sits alongside AFCS for attributable conditions, so AFCS case law matters because the same PIC may be driving both the ill-health pension and the compensation claim. Cases such as AK v Secretary of State for Defence [2025] UKUT 032 (AAC) and MJU v Secretary of State for Defence [2025] UKUT 033 (AAC) emphasise that caused by service is not always a simple or narrow concept. The Upper Tribunal has made clear that AFCS is a no-fault scheme and that there is no thin skull rule excluding someone simply because they were particularly vulnerable. That is useful in AFPS 2015 PIC cases for at least two reasons. First, it pushes back against the familiar tendency to suggest that someone was predisposed, constitutionally fragile, or otherwise inconveniently human. Second, it helps where the same PIC is being minimised on one side of the house while being examined more seriously on the other. If the law recognises that service can still be causative despite vulnerability or complexity, that should make it harder for the state to shrug off the condition as not really service-related or not really as functionally serious as the member says.

Bano's treatment of causation under AFCS is particularly careful on this point. He sets out the four-stage approach from the case law: identifying the relevant causes, disregarding those too remote to matter, separating service-related from non-service-related causes, and deciding whether service was the predominant cause. That is a structured and sometimes demanding exercise. The practical relevance to AFPS 2015 is that a vague PIC can make both the pension case and the AFCS case harder to frame. Conversely, a later AFCS award may depend on a more precise medical description than the one used at discharge. That is where same condition disputes begin to emerge, and where the original FMed 23 wording can start to cause real downstream damage.

AFPS 2015 cares about function, not optimism

JSP 950 and AGAI 78 are helpful here because they show how the medical system is supposed to think. JSP 950 says that medical grading must be based on functional capacity. It is not enough to ask whether a person can technically still perform a sliver of their current role. Medical assessment must take account of general service duties, branch and trade duties, and deployed duties. AGAI 78 makes the same point through the PULHHEEMS and JMES system. The medical grading is about employability and deployability, and the FMed 23 narrative should record employment restrictions and functional consequences.

So if the PIC says lumbar disc injury but the medical limitations show inability to sit for long periods, inability to stand for long periods, inability to march, unfitness for strenuous physical exertion, and office duties only, then the real argument is not just about the diagnosis. It is about the actual practical consequences of the diagnosis. The MedLim codes in JSP 950 are useful precisely because they are the bureaucracy's own acknowledgment that function matters. Codes recording unfitness for strenuous physical exertion, requirement to be seated, fitness for sedentary duties only, inability to sit or stand for long periods, office duties only, or unfitness for safety-critical work all help tell the real story behind the PIC. If the pensions side later acts as though the PIC is a mild inconvenience, the medical restrictions may say something very different.

The review power cuts both ways

AFPS 2015 has a more explicit internal review power than many people realise. JSP 905 says the scheme manager may review a member's condition if an active member is entitled to a Tier 2 or Tier 3 award, or a deferred member is receiving early payment because of ill-health, and it appears that the condition has changed. That means AFPS 2015 reviews cut both ways. A member can seek a review because things have deteriorated. But the scheme manager may also review and conclude that a Tier 3 member is now only Tier 2, or that a Tier 2 member no longer meets Tier 2 at all. The scheme recognises that health is dynamic. It just also reserves the right to draw its own conclusions about the direction of travel.

The five-year review route for members is worth understanding carefully. JSP 905 says the request must be made in writing, must include reasons, and can be made within five years or later in exceptional circumstances. The scheme manager must consider whether the member had actually suffered a more serious breakdown at the original time, or whether the condition has genuinely worsened since. That distinction matters because one route suggests the original decision was wrong from the start, while the other accepts the original decision was reasonable but the position has since changed. Same PIC, different legal argument, and potentially different consequences for backdating and financial outcome. If a Tier 1 lump sum has already been paid, a successful move upward may mean that original payment has to be repaid or offset. The scheme recognises deterioration. It just also does the maths with great seriousness afterwards.

The same condition problem and GIP interaction

One of the pension world's more frustrating features is the way one successful claim can interfere with another. Under AFPS 2015, if a Guaranteed Income Payment is received under AFCS, it is adjusted to reflect income streams already received under AFPS 15. If the ill-health pension is for the same injury as the GIP, the entire pension is taken into account. If the tier later increases from Tier 1 to Tier 2 or Tier 3, the full annual value of the ill-health pension may be deducted from the GIP.

That makes the same injury question enormously important. And that means the PIC matters enormously, because the PIC is often the official answer to the question of which condition actually brought about the discharge. Bano's analysis of same condition disputes is directly relevant here. A better diagnosis later on does not automatically create a new condition. Sometimes it simply reveals what the condition always was. If the pension side names the discharge-causing condition one way and the AFCS side uses a more precise description, the member can find themselves in a bureaucratic argument about whether two descriptions refer to the same injury, while their actual body remains stubbornly singular. The original FMed 23 wording is often where that argument either holds together or starts to unravel.

Transitional protection and the final salary link

JSP 905 and the parliamentary material on AFPS 2015 both emphasise transitional protection. Those within ten years of their previous scheme's normal pension age on 1 April 2012 stayed in their legacy scheme and did not transfer to AFPS 2015. Others moved, but their accrued legacy rights were protected. In real life, AFPS 2015 PIC cases therefore come in broadly three varieties: pure AFPS 2015 cases involving newer entrants with only 2015 rights; hybrid cases involving legacy rights plus AFPS 2015 membership; and protected legacy cases where there is no real AFPS 2015 membership for the relevant period. A lot of cases arrive carrying luggage from 1975 or 2005, and the PIC has to operate across all of it.

The final salary link is one of the most important protected features. JSP 905 confirms that where continuous service is maintained, legacy scheme benefits stay linked to the final salary or rank achieved at the end of military service, including service within AFPS 15. That is a deceptively significant point. It means the PIC may trigger discharge in the AFPS 2015 era, but the financial effect can still spill back into the value of protected AFPS 75 or AFPS 05 rights. The condition that ends service under AFPS 2015 may also determine when that legacy final salary link crystallises. In plain terms, the PIC may help decide not only whether the member leaves, but when, and that timing may affect legacy pension calculations as well.

Challenging the PIC: the one-year window

AGAI 78 brings in a very practical and very important point. If a service person or ex-service person believes their PIC code should be changed, they must appeal using Appendix 20 via the Unit CO to the Regional Clinical Director or ROHT. The time limit under current policy is 12 months from discharge or retirement. That is easy to miss and very painful to miss. So if the FMed 23 has the wrong principal condition, or if the right condition has been described so vaguely that it drains away the seriousness of the case, the system does not give unlimited time to sort it out. AGAI 78 also makes clear that FMed 23 paperwork for those medically discharged with two years or more service is sent to Veterans UK. The original medical wording does not stay inside the medical world. It travels straight to the people who will later be making pension and compensation decisions.

As noted in the earlier review of this guide against Bano, the twelve-month deadline should be treated carefully. It reflects current policy, but policy can change, and there may be circumstances where later challenge remains possible through other routes. The practical advice remains simple: if the PIC is wrong, raise it early and clearly, and do not assume the deadline is the only consideration.

IDRP and the formal dispute route

If the pension consequences of the PIC have been applied wrongly, AFPS 2015 provides a formal internal dispute resolution procedure through DBS Veterans UK. It covers disagreements of fact, law, or maladministration and is a single-stage process. That is not the same as challenging the PIC code through the medical chain, and it is not the same as an AFCS appeal. JSP 905 adds that if the scheme manager proposes to change or reduce a pension after a review, it must notify the member in writing, give reasons, and tell them about their rights under the dispute arrangements and the Pensions Ombudsman route. So the paperwork has to explain itself. That is at least something.

The bottom line on AFPS 2015 and PICs

AFPS 2015 is the scheme where the PIC enters the CARE era, picks up a rucksack full of legacy rights, and then gets marched past a row of legal requirements asking whether the decision-maker has explained themselves properly. It still tells the system what ended the military career. It still helps determine the ill-health tier. But now it also has to operate inside a scheme built around career-average earnings, a normal pension age of 60, transitional protections, protected legacy rights, final salary links, review powers, functional restrictions, AFCS and GIP interaction, a time-limited window to challenge the PIC code itself, and a body of Upper Tribunal case law saying that categories need evidence, baselines matter, and reasons are not optional.

Bano's analysis of the legal framework for war pensions and AFCS is useful throughout because it keeps returning to the same discipline: disablement is a functional concept, causation requires proper analysis, and decision-makers cannot simply announce conclusions and expect them to stand. Those principles do not disappear when the scheme changes. They follow the PIC through every system it touches.

So if AFPS 75 was about attributable invaliding, and AFPS 05 was about employability tiers, AFPS 2015 is about managing the same old human damage inside a newer, more structurally tidy pension machine, while the courts stand nearby making sure the machine at least explains what it is doing. Under AFPS 2015, the PIC is still the diagnosis that ended service. It just now has to file its paperwork in three different systems, survive a baseline analysis, hold together a legacy rights calculation, and be ready for cross-examination before lunch.

War Pension Scheme:

where the PIC meets a more claimant-friendly law

The War Pension Scheme is the compensation scheme for illness, injury and death caused by service before 6 April 2005. It is older than AFCS and structurally very different, but older does not mean weaker. In some of the most important respects, especially proof, WPS can be markedly more favourable to the claimant than the modern scheme that replaced it. That is one of the central themes that comes through strongly from Bano’s treatment of war pensions. The legal architecture is not simply a historic curiosity. In the right case, it still gives veterans a materially better platform from which to argue service attribution.

The Primary Invaliding Condition matters here because it often sits at the join between discharge and compensation. The PIC is not itself a WPS concept in the same way that a tariff descriptor is an AFCS concept. It begins earlier, in the medical board and discharge process, as the official condition said to have brought military service to an end. But once a veteran later claims under WPS, that discharge condition may become highly relevant. It may help identify what condition is being claimed, whether the chronology makes sense, whether the condition accepted under WPS is the same one that caused invaliding, and whether pension and compensation consequences should be treated as flowing from the same underlying disablement.

That is why the PIC can matter even in a scheme that is not built around it. If the PIC is accurate, medically coherent and properly rooted in the service story, it provides a strong bridge into the later WPS case. If it is weak, vague or misleading, the veteran may later find themselves trying to prove not only that the condition was due to service, but also that the discharge paperwork was talking about the same thing all along, just badly.

Bano is particularly helpful on the conceptual side of this because he repeatedly distinguishes between diagnosis, disablement and attribution. WPS is not concerned merely with whether some diagnosis can be attached to the veteran. It is concerned with disablement and whether that disablement is due to service. That is an older but often more humane way of looking at the problem. A person may have a broad diagnostic label, but the legal question is what disablement they actually suffer and whether service caused or worsened it. That means PIC wording matters, but not only because labels matter. It matters because weak wording can obscure the real disablement and weaken the apparent service link.

The burden of proof is where WPS becomes especially important. One of the enduring claimant-friendly features of the war pensions regime is the reverse burden principle. In the right case, once the claim reaches the stage where there is a proper case to answer, the Secretary of State must disprove service attribution beyond reasonable doubt. Bano’s explanation of this remains one of the clearest reasons why WPS should never be treated as a relic. The claimant still needs a coherent case. Records, chronology and medical evidence still matter. But the law is not asking the veteran to prove every inch of causation in the ordinary civil sense. It places a heavy burden on the state once the threshold for a live issue is crossed.

That makes the PIC important in a very practical way. A clear principal condition, recorded close to discharge and tied to the real service history, can make it much harder for the state to argue later that the condition was really something vague, something natural, something constitutional, or something unconnected with service. A weak PIC does not destroy a WPS case, especially given the burden rules, but it can still create avoidable difficulty. If a traumatic service injury has been reduced to a generic symptom label, the veteran may spend years unpicking language which should never have been allowed to flatten the facts in the first place.

The FMed 23 is therefore still highly relevant in WPS work. Even though WPS is a compensation scheme rather than a discharge scheme, the medical board documents often contain the earliest formal account of the principal condition, the date of origin, the place of origin, and the board’s narrative of what was going on. Those details matter because WPS cases are often highly sensitive to chronology and service context. When did the condition arise? When was the claimant first removed from duty? Was there in-service aggravation? Was there a specific event, exposure or period of service which triggered the disablement? If those details are well recorded, the later WPS case starts with a coherent factual skeleton. If they are missing or blurred, the department may try to exploit that uncertainty.

This is also where Bano’s emphasis on proper legal analysis rather than mere administrative shorthand is so useful. A war pension case should not be decided by bureaucratic atmosphere. It should be decided by asking the right questions about disablement and attribution. Yet in practice many disputes begin because the paperwork chose weak or generic language. “Back pain”, “joint pain”, “low mood”, “hearing difficulty” or “functional symptoms” may all be technically possible descriptions, but they can be hopelessly poor legal summaries if they fail to preserve the injury mechanism, service context, severity or progression of the condition. WPS may be more flexible and less descriptor-bound than AFCS, but it still depends on the paperwork telling the truth well enough for the law to work properly.

The classic WPS/PIC problems tend to repeat themselves. Sometimes the PIC is too generic and strips out the real injury. Sometimes the service story disappears, so that an operational or training-related injury is redescribed as something mild, ordinary or degenerative. Sometimes the wrong condition is given top billing, while the true service-ending condition is tucked away as secondary. Sometimes the condition later accepted under WPS is described more precisely than the condition used at discharge, and the department then tries to suggest that they are different conditions rather than different ways of describing the same disablement. Sometimes the full medical evidence is strong, but the summary passed onward is much weaker.

That last problem deserves special emphasis. One of the most practically valuable lessons, and one that sits comfortably with Bano’s wider analysis, is that under-described evidence can poison the whole case. A full medical report may record major functional loss, clear service chronology, and a serious disabling condition, only for the official summary to smooth all of that into a much safer administrative paragraph. Once that happens, downstream reasoning may look calm and orderly while resting on a shrunken account of the facts. That is why in a WPS case it is often essential to compare the full report, the summary, and the final decision. A great deal can disappear in transit.

The “same condition” issue is another area where WPS and PICs intersect in a financially important way. If a veteran secures a WPS award for the same condition that caused discharge, that may affect whether the linked pension is treated as tax-free. That sounds straightforward until the paperwork starts using different language at different stages. If discharge records say one thing and the later WPS award uses more precise or slightly different terminology, the system may try to behave as though it is dealing with separate illnesses rather than one condition described with differing levels of competence. Bano’s discussion is valuable here because it reinforces a point that runs through a lot of these cases: a better later diagnosis does not automatically mean a different condition. Often it means the original condition has finally been named properly.

That matters because a veteran can win the attribution point under WPS and still find other systems awkward or resistant. The pension side, tax treatment, and old attributable benefit structures do not always move in perfect harmony just because WPS has accepted service causation. Different legal structures can produce different administrative arguments. In that landscape, the PIC is one of the few stable anchors. It is often the earliest formal statement connecting the discharge, the medical reality and the later compensation claim. If it is good, it helps hold the systems together. If it is bad, every later process gets more inclined to speak its own dialect about the same damaged body.

The evidence that helps most in WPS/PIC cases is usually a combination of medical board material, chronology, service context, consultant evidence and functional evidence. The medical board records matter because they provide the original official description. Chronology matters because attribution questions are often won or lost on timing and sequence. Service context matters because the old scheme is centrally concerned with whether service caused or worsened the disablement. Consultant evidence matters because it can explain why differently worded labels are in fact describing the same underlying condition. Functional evidence matters because WPS is ultimately concerned with disablement, not just nomenclature.

When reviewing the papers, the most useful questions are often the simplest ones. Does the PIC reflect the real condition that ended service? Is the date of origin accurate? Is the place and service context properly preserved? Has the condition been described too blandly? Does the later WPS paperwork use different language, and if so is that medically justified or merely administratively convenient? Has the disablement been described properly, or reduced to something safer and smaller? Those questions are not academic. They often expose whether the paperwork is helping the truth survive or quietly burying it.

The emotional difficulty of WPS cases is that many veterans look at them and think the service link should be obvious. Sometimes it should. The condition arose in service, the member was removed from duty, the disablement is real, and the records exist. Yet the dispute still happens. That is partly because even a claimant-friendly burden of proof cannot rescue a case from every administrative distortion. The law may give the veteran the benefit of the doubt, but the record still needs to preserve enough of the real story for that principle to do useful work.

The bottom line is that the War Pension Scheme remains one of the most important parts of this area of law precisely because it can be generous on proof where the modern scheme is not. But that generosity does not make the paperwork irrelevant. The PIC matters because it often helps establish what condition ended service, what condition is now being claimed, how the chronology works, how the service story is preserved, and whether pension and compensation are really dealing with the same disablement. Under WPS, the law may be prepared to give the veteran the benefit of the doubt. The job of the paperwork is to make sure the doubt is being asked about the right condition in the first place.

WPS vs AFCS: 

when the same condition enters two different legal systems

If the Primary Invaliding Condition is the sentence that ends a military career, the next question is often which compensation system that sentence now belongs to. In practice, that usually means one of two worlds: the War Pension Scheme or the Armed Forces Compensation Scheme. The dividing line sounds simple enough. Broadly, WPS covers illness, injury or death due to service before 6 April 2005, while AFCS covers injury, illness or death caused by service on or after 6 April 2005. But as Bano’s analysis makes clear, the real difference is not just one of date. These are two different legal models of compensation, and the PIC can matter in both for different reasons.

The PIC usually begins on the discharge side rather than the compensation side. It is the condition recorded as the principal reason for invaliding or medical discharge. That matters in both WPS and AFCS because each scheme later needs to know what the condition actually was, when it arose, whether service caused or worsened it, and whether the compensation claim is really about the same condition that ended service. So the PIC often becomes the bridge between medical discharge, pension consequences and compensation. If that bridge is accurate, the case may still be hard, but at least it starts from a coherent medical story. If it is weak, vague or misleading, the veteran may later find themselves arguing not just about what happened, but about why the paperwork described it so badly.

That is where Bano is especially useful. One of the recurring strengths of his treatment is that he does not let these schemes collapse into mere battles of labels. He distinguishes between the disablement, the injury or pathological process causing it, and the legal question of service causation. That distinction matters in both WPS and AFCS. A generic label may be medically possible, but still legally unhelpful if it obscures the real disablement, the real pathology, or the real service story. The PIC is therefore not important simply because it is a diagnosis. It is important because it is often the first official account of the condition that later has to survive legal scrutiny in a compensation system.

The War Pension Scheme is the older of the two, but in some respects it is more favourable to claimants. Bano’s discussion of war pensions makes this very clear. WPS is built around disablement due to service and includes evidential principles that can be markedly more claimant-friendly than those in AFCS. In the relevant class of case, once there is a proper case to answer, the Secretary of State bears a heavy burden to disprove service attribution beyond reasonable doubt. That is a very different atmosphere from modern compensation law. It does not mean every WPS case is easy, and it does not mean weak evidence stops mattering. But it does mean that the law is often more willing to help the veteran once a credible attribution case has been raised.

That more favourable proof structure is one reason why the PIC still matters so much under WPS. A strong, well-recorded PIC can provide a powerful starting point for the service story. It can show what condition ended service, when it arose, and how the discharge and compensation narratives fit together. A weak PIC does not necessarily destroy a WPS case, because the legal burden rules may still help the claimant recover the position. But it can still create unnecessary difficulty. If a traumatic or service-worsened condition has been reduced to a bland label such as “back pain” or “low mood”, the department may later try to treat the condition as vaguer, smaller or less clearly attributable than it really was. So although WPS is often more forgiving of weak paperwork than AFCS, there is still no advantage in letting the paperwork undersell the truth.

AFCS works differently. It is the newer scheme and much more tightly structured around descriptors, tariff levels and statutory categorisation. Bano’s treatment of armed forces compensation law shows why that matters. AFCS is not simply a modern version of WPS. It asks different questions in a different way. The decision-maker must identify the accepted injury or illness, decide how it fits within the scheme’s legal categories, and apply a more structured causation analysis. In that environment, wording becomes especially important. A weak or flattened PIC can distort the claim much earlier, because the condition has to be matched against descriptor language and tariff logic from the outset.

That is why AFCS often feels less forgiving of bad wording than WPS. Under WPS, a claimant may still be helped by the evidential structure once the real service case is properly raised. Under AFCS, a bad starting description can skew the whole categorisation exercise. If the real condition is something like a traumatic spinal injury, serious psychiatric illness, neurological damage or a complex orthopaedic condition, but the PIC or summary language turns it into something generic and bloodless, the descriptor analysis may begin from a diminished version of the truth. In that sense, AFCS is not simply “stricter.” It is more dependent on accurate categorisation at the start.

A useful shorthand, broadly consistent with Bano, is that WPS tends to focus more on disablement and attribution, while AFCS tends to focus more on categorisation and descriptor fit. That is not an absolute rule. WPS still cares about medical identification, and AFCS still cares about consequences. But as a practical distinction it helps. Under WPS, the real fight is often whether this is the service-caused disabling condition and to what extent it has disabled the veteran. Under AFCS, the real fight is often whether the condition has been correctly characterised in legal terms and whether it fits the right descriptor at the right level.

The “same condition” issue matters in both schemes, and Bano’s analysis is especially helpful here. A better later diagnosis does not automatically mean a different condition. Sometimes it simply means that the same underlying pathology has finally been described properly. That is a vital point in both WPS and AFCS cases, because discharge paperwork, compensation decisions and pension paperwork often use different language for what may in substance be the same disablement. A discharge record may say “back pain”, a WPS decision may refer to a service-related spinal injury, an AFCS decision may use a more precise diagnostic phrase, and the pension papers may use something broader again. The legal question is not just whether the words differ. It is whether the underlying condition is in fact the same.

That matters because the “same condition” issue can affect money as well as coherence. If a WPS or AFCS award relates to the same condition that caused discharge, that may affect tax treatment on the pension side. Under AFCS there is also the Guaranteed Income Payment interaction. If the claimant receives a GIP and an ill-health pension for the same injury, the pension may be brought into account in the GIP calculation. That creates one of the stranger features of the modern system: proving that pension and compensation concern the same condition may help establish consistency and tax consequences, while also reducing the compensation stream through offset. WPS does not reproduce that exact structure in the same way, which is one reason the two schemes feel so different in practice.

The overlap cases are where this comparison becomes most difficult and where the PIC often matters most. Some conditions do not begin neatly on one side of 6 April 2005 and stay there. Symptoms may begin before 2005, worsen after 2005, lead to discharge years later, and produce pension and compensation questions under more than one scheme structure. In those cases, the legal line remains neat, but the facts do not. Bano’s framework is particularly valuable here because the answer may depend on careful analysis of chronology, pathology, aggravation and whether later deterioration is part of the same underlying condition or something legally distinct. In practical terms, that makes the PIC, its date of origin, its place of origin and the surrounding narrative especially important.

The legal frameworks reinforce this difference. WPS sits within the older war pensions structure dealing with disablement due to service before 6 April 2005. AFCS sits within the post-2005 statutory compensation scheme, including the Armed Forces and Reserve Forces (Compensation Scheme) Order 2011. So this is not just a matter of bureaucratic mood. The distinction is built into the legislation. The PIC matters because it often becomes the factual hinge connecting the discharge system to whichever legal compensation world applies afterward.

Despite those differences, the same administrative weaknesses can appear in both schemes. This is another point that fits well with Bano’s wider approach. Whether the scheme is asking about disablement and attribution or descriptors and tariff levels, decision-makers still need to identify the right facts, apply the right legal test and explain their reasoning. Bad decisions in both schemes often suffer from the same vice: the conclusion is presented as if it were self-evident, when in fact it rests on weak findings, thin summaries or unexplained assumptions. Under WPS that may mean the disablement picture has been understated or the service link brushed aside. Under AFCS it may mean the wrong descriptor has been chosen or the causation analysis has been mishandled. Different schemes, same problem.

The practical bottom line is that WPS and AFCS reward and punish different things. WPS is often better for claimants on proof. AFCS is generally clearer in structure but less forgiving of weak medical wording. WPS is more likely to produce arguments about disablement, attribution and the state’s burden to disprove service connection. AFCS is more likely to produce arguments about descriptors, categorisation and GIP interaction. In both systems, though, the PIC matters for the same underlying reason: it is often the first official statement of the condition that later has to carry the weight of compensation law.

So if the shortest summary is needed, it is this. WPS is the older compensation scheme for service-caused conditions before 6 April 2005 and is often markedly more favourable to claimants on proof. AFCS is the newer compensation scheme for service-caused conditions on or after 6 April 2005 and is more structured, more category-dependent and often less forgiving of weak descriptions. In both schemes, the PIC matters because it helps determine what condition ended service, what condition is now being compensated, how the chronology works, how service causation is argued, and whether pension and compensation are really dealing with the same disablement. The legal dividing line may be 6 April 2005. The practical dividing line is often whether the condition was described well enough at discharge for the right scheme to analyse the right injury afterward.

Overlap / spanning cases: 

when one condition has to survive several legal systems

If the armed forces pension and compensation system were built around tidy lives, most cases would be simple. There would be one condition, one clear date of onset, one clean discharge, one pension scheme, one compensation scheme, and one decision-maker speaking in complete sentences. Real life is less cooperative. Real life gives you an injury in 2004, deterioration in 2006, discharge in 2008, a pension under one structure, compensation arguments under another, and a later dispute about whether the condition now being recognised is really the same condition that ended service in the first place. That is the territory of overlap or spanning cases.

These are the cases where the neat legal boundaries, especially the line at 6 April 2005, collide with the untidier way illness, injury and disablement actually develop over time. In these cases, the Primary Invaliding Condition often becomes more important than usual, because it may be one of the earliest formal records of what condition the system thought had actually ended service. Once several different legal structures begin looking at the same medical history from different angles, that early description can become crucial.

A spanning case is not a special category with one magic legal test. It is simply a case in which the important parts of the story do not sit neatly within one legal period or one scheme. The injury may have begun before 6 April 2005 and worsened later. Symptoms may have started years before a firm diagnosis was reached. Discharge may have happened under AFPS 05 or AFPS 15 even though the underlying condition began in earlier service. The compensation claim may be analysed under one scheme while the pension consequences sit under another. Or the condition recorded at discharge may later be described in different terms in WPS, AFCS or tax-related decision-making. These are not rare cases. They are simply the cases in which the law’s preference for tidy categories runs up against the body’s preference for gradual deterioration, evolving diagnosis and bad timing.

The legal boundary at 6 April 2005 still matters enormously. Broadly speaking, service-caused illness, injury or death before that date points toward the War Pension Scheme, while injury, illness or death caused by service on or after that date points toward AFCS. That is the compensation divide. But Bano’s approach shows why the date line cannot do all the work on its own. The real questions are more precise. What is the underlying injury, illness or pathological process? When did it arise? When did it become disabling? Was later deterioration simply progression of the same condition, or was it something legally distinct? Was later service part of the causation story? Those questions cannot be answered by looking at the calendar alone.

That is why overlap cases are so difficult. The law tends to ask: what is the condition, and when was it caused? The body often gives a more complicated answer. It may have started here, worsened there, become undeniable later, and ended the career only after years of development. A typical example would be service-related knee trauma in 2004, worsening pain and instability through 2005 to 2007, discharge under AFPS 05 in 2008, and a later diagnosis of osteoarthritis or meniscal damage. To the claimant, that is one coherent story. To an administrative system, there is always a temptation to break it into separate pieces: an early injury, a later degenerative condition, a discharge condition, a compensation condition, perhaps even a pension condition described in yet another way. Once that happens, entitlement arguments start to fracture as well.

This is where the PIC can become especially valuable. In an ordinary case, the PIC matters because it identifies the principal discharge-causing condition. In a spanning case, it may matter even more because it may be the earliest official attempt to record what the main condition actually was, when it began, where it began, and what the service medical process thought had truly ended service. A strong PIC can help answer some of the most important questions in a spanning case. Was the discharge-causing condition already present before the scheme boundary? Is the later diagnosis merely a better name for the same condition? Is the compensation claim concerned with the same underlying injury or pathological process? Are the pension and compensation systems really discussing the same body, the same chronology and the same medical story?

Bano’s treatment of “same condition” issues is particularly helpful here. One of the most important points is that a later and better diagnosis does not automatically create a different condition. Sometimes it simply identifies more accurately what was there all along. That matters enormously in overlap cases. Symptoms before 2005 and diagnosis after 2005 do not necessarily mean two different conditions. “Back pain” later refined into “lumbar disc prolapse with radiculopathy” may still be one coherent spinal story. “Knee pain” later refined into traumatic degenerative change may still be one coherent knee story. “Low mood” later understood as depressive disorder or PTSD may still be one continuous psychiatric story. The legal question is not whether the wording changed. It is whether the underlying condition is in substance the same.

That is also why chronology is so important. In a spanning case, chronology is not background detail. It is often the spine of the entire argument. It helps determine when the condition first arose, when symptoms first appeared, when the condition became functionally serious, when service restrictions were imposed, when discharge became likely, when diagnoses changed, when deterioration occurred, and when pension or compensation decisions were made. Without a disciplined chronology, it becomes much easier for a continuous condition to be redescribed as a series of separate episodes. With a disciplined chronology, it becomes much easier to show continuity of pathology, continuity of disablement and continuity of administrative recognition.

The FMed 23 and the medical board material become especially important in this context. The PIC wording matters, but so do the associated details such as date of origin and place of origin. In spanning cases, those entries may be among the most important pieces of contemporary evidence. They may support the argument that the condition existed before the 2005 boundary, that it arose in service or on operations, that the later diagnosis is simply a later articulation of the same condition, or that the discharge-causing condition was already clearly established before the pension or compensation machinery began applying later scheme structures. If those entries are weak, vague or wrong, the claimant may later find themselves having to reconstruct a chronology that should have been recorded properly at the time.

Spanning cases often produce recurring patterns. One is the classic pre-2005 injury with post-2005 discharge: for example, a service-related spinal injury sustained before 6 April 2005 that worsens over time and eventually leads to discharge under AFPS 05 or AFPS 15. Another is symptoms before 2005 with diagnosis after 2005, which is common in psychiatric cases, chronic pain, hearing loss and some neurological conditions. Another is one condition carrying several labels over time, so that what begins as “knee injury” becomes “instability,” then “chronic pain,” then “degenerative osteoarthritis.” Another is service aggravation across the date line, where an existing condition is materially worsened by later service and the legal issue becomes whether that worsening is part of the same condition, a separate compensable event, or both in different respects. None of these patterns is especially exotic. They are simply examples of the law meeting a real timeline.

In many of these cases, the practical fight becomes a fight about continuity. Not continuity in the sense that the claimant knows they have gone on suffering, but continuity in the sense that the legal system is willing to recognise one continuous underlying condition despite changing language, diagnostic development and different scheme structures. That is why the “same condition” issue becomes so central. A lot can turn on whether the later accepted condition is treated as the same condition that caused discharge. That may affect tax treatment of the pension, interaction with AFCS Guaranteed Income Payment, and whether the overall case remains coherent across different systems. What appears to be a dispute about wording is often really a dispute about whether one continuous service-related condition is being artificially broken into administratively separate fragments.

This is also where the different pension schemes add another layer of complication. The compensation side may involve WPS or AFCS depending on when the service-caused condition arose or worsened, while the pension side may sit under AFPS 75, AFPS 05 or AFPS 15 depending on service history and discharge timing. Those are different legal structures asking different questions. A spanning case may therefore involve WPS-style attribution questions, AFCS-style causation and descriptor issues, AFPS 05 or AFPS 15 tiering, tax-free pension arguments, and same-condition disputes all at once. That is not exaggeration. It is often the actual shape of the case.

Bano’s wider approach is useful here because it resists the temptation to let labels do all the work. The real task in a spanning case is to separate out and then reconnect the key questions: what is the disablement, what is the underlying pathology, what is the chronology, what part of the story is attributable to service, and how do the legal schemes map onto that factual history? Decision-makers often get into trouble when they simplify too early. A vague factual finding, a compressed medical summary, or an unexplained change in wording can distort the case across several legal systems at once. That is why spanning cases are especially vulnerable to bad reasons and weak fact-finding.

The evidence that matters most is usually straightforward in kind, even if difficult in practice. First comes chronology: dates of symptoms, treatment, downgrading, restrictions, discharge, diagnosis and deterioration. Then the medical board papers, especially the FMed 23, PIC wording, origin details and functional findings. Then consultant evidence explaining whether later diagnoses are simply more specific descriptions of the same underlying condition. Then functional evidence over time, showing continuity and deterioration. Then comparative wording across documents, exposing where the system has quietly shifted the description. And finally, service context, because the question is never purely medical; it is also about how the condition arose and how service affected it.

The argument in a good spanning case is often simple in principle even if hard in evidence. It usually comes down to something like this: the condition that caused discharge is the same underlying condition later described in more specific terms in specialist and compensation evidence, and the difference is one of wording and diagnostic development rather than genuinely separate conditions. Or, where appropriate, the argument may be that the condition began before 6 April 2005 and continued or worsened thereafter, and the later presentation should not be treated as administratively separate merely because the label became more precise. In other cases, the argument may be that the decision has artificially divided one continuous service-related condition into separate conditions in a way that is inconsistent with the chronology, medical evidence and discharge record.

The practical bottom line is that overlap cases are where the law’s neat boundaries are under the greatest strain. The legal line at 6 April 2005 remains important, but it does not answer every question. The real issue is often whether the same underlying condition is being analysed consistently across time despite changes in diagnosis, language, severity and legal framework. In those cases, the PIC may matter more than anywhere else, because it may be the earliest official record of what condition really ended service. If it is accurate, it can help preserve one coherent medical story across several legal worlds. If it is weak or generic, one continuous condition can very easily be chopped into several administratively useful pieces.

Challenging pension and compensation decisions

If you are reading this section, one of two things has probably happened. Either a decision has arrived in calm official prose explaining that your condition is apparently less serious, less service-related, or less financially significant than your body has been suggesting for quite some time, or you have realised that the system has described the same condition differently at so many stages that nobody now seems entirely sure which bit of you is being argued about. This is the stage after the medical board and discharge process, when the dispute shifts from the condition itself to what the law and the paperwork have done with it.

That distinction matters. Sometimes the underlying condition has been recorded broadly correctly, but the pension or compensation decision built on it is still wrong. Sometimes the problem is factual rather than medical: the decision-maker has misunderstood the chronology, understated the functional impact, or treated one continuous condition as if it were several unrelated problems. Sometimes the issue is legal: the wrong test has been applied, the scheme rules have been misread, or the decision-maker has reached a conclusion without explaining how the evidence supports it. And sometimes the problem is administrative: delay, mishandling, bad record use, failure to follow policy, or a summary that bears only a passing resemblance to the report it claims to represent. Bano’s wider lesson is that it is a mistake to treat all of these as one complaint. The first task is always to identify what kind of decision is being challenged and what kind of error is actually being alleged.

That is more important than it sounds. In this field, the same condition can produce a pension decision, a compensation decision, a review decision, a tax consequence, a same-condition dispute, and a complaint about maladministration, all without anybody pausing to simplify matters out of kindness. A challenge to the PIC itself at medical discharge is one thing. A challenge to the pension tier that followed from it is another. A challenge to an AFCS descriptor is another again. A complaint that the decision rests on an inaccurate summary of the medical evidence is something else. If you do not separate these out, the system may very efficiently answer a different question from the one you are actually asking.

The basic route map is therefore important. If the issue is a pension scheme decision, the starting point is usually the Internal Dispute Resolution Procedure, or IDRP. If the issue is a War Pension Scheme or AFCS compensation decision, the challenge usually follows the appeal structure for that scheme. If the issue is maladministration in pension handling, the Pensions Ombudsman may become relevant once the internal route has been exhausted. If the issue is broader unfairness or mishandling within service structures, a Service Complaint may sometimes form part of the picture. And if the issue is really that the original PIC or discharge route was itself wrong, that is usually an earlier and separate fight. These routes can interact, but they are not interchangeable.

IDRP is the main formal route for saying that the armed forces pension scheme has been applied wrongly. That includes disagreements about fact, law and maladministration. In practical terms, this is where you challenge things like the wrong ill-health tier under AFPS 05 or AFPS 15, the wrong interpretation of functional evidence, an incorrect same-condition analysis affecting tax treatment, a mistaken approach to legacy rights in a hybrid AFPS 15 case, or a review decision that reduces or removes entitlement without adequate justification. The point of IDRP is not simply to say the result feels unfair. It is to say that the scheme has answered a pension question wrongly and to explain why.

That is where Bano’s emphasis on precision becomes especially useful. A good pension challenge does not just complain in general terms. It identifies the decision, the legal or scheme issue, the factual basis of the challenge, the evidence that supports it, and the outcome sought. For example, the complaint may be that the scheme has treated the discharge-causing condition as different from the condition accepted for compensation purposes despite consultant evidence showing that they are the same underlying pathology. Or it may be that the decision to maintain Tier 1 does not engage with the evidence of significant functional restriction and gives no adequate reasons for concluding that civilian earning capacity is not significantly impaired. Or it may be that a review decision has reduced the award without explaining why the accepted condition no longer satisfies the relevant criteria. Those are usable legal complaints. “Everything about this is unfair” may be emotionally correct and legally useless.

The distinction between review and correction of the original decision is also critical. Under AFPS 05 and AFPS 15, there is often a route for review if the member’s condition worsens in an unexpected way within the relevant period after discharge. But that is not the same argument as saying the original decision was wrong when made. One route says, in effect, that the evidence then available should have produced a different outcome. The other says that the original outcome may have been correct at the time, but the condition has since deteriorated beyond what was expected. Those are different legal positions and they can lead to different consequences, including different effective dates for any increased entitlement. A challenge should therefore make clear whether it is really alleging original error, later deterioration, or both in the alternative.

Once you move beyond pensions into WPS and AFCS, the shape of the dispute changes but the same discipline still applies. A War Pension Scheme case is often about attribution to service, degree of disablement, worsening, or whether the original medical picture was understated. Bano’s treatment of war pensions is especially helpful here because it shows how much these cases turn on the real disablement and the actual service story rather than a polished label. In the relevant class of WPS case, the evidential structure is generally more favourable to the claimant than in AFCS, but that does not remove the need for precision. The veteran still needs to show what the real condition was, what the disablement actually consisted of, how the chronology fits together, and where the decision-maker has gone wrong in law or fact. A recurring WPS problem is the thinned-out summary: a full report records serious disablement, service chronology and functional loss, but the official account downstream turns it into something tidy, generic and much less helpful. When that happens, the challenge may be framed as failure to apply the correct policy, failure to engage with the evidence, factual error, or inadequate reasons depending on the form of the decision.

AFCS disputes tend to look different because the scheme is more structured, more descriptor-led and more openly tied to tariff logic. Here the recurring issues are whether the right descriptor has been used, whether service causation has been assessed correctly, whether the tariff level is right, whether Guaranteed Income Payment should be paid, and when it should begin. This is where Bano’s emphasis on legal framing and tribunal reasoning is especially useful. A decision that merely announces a descriptor outcome is not enough. The real question is whether the decision-maker has identified the right factual baseline, compared the evidence to the competing legal categories, and explained why one descriptor fits better than another. The Upper Tribunal cases underline that decisions of this kind must show their workings. A conclusion without reasoning is often the point at which the challenge begins.

One of the most useful legal tools across both pension and compensation disputes is the baseline question. Compared with what? If the decision says the claimant’s civilian employability is not significantly impaired, the obvious question is what kind of work is being used as the comparison. Real work suited to the claimant’s qualifications, service background and restrictions? Work that can be sustained full time in the real world? Or an unspecified fantasy role populated by people with no fatigue, no pain, no mental health symptoms and no limits on concentration, sitting or standing? The same problem arises in AFCS descriptor reasoning. If the decision says the condition does not justify the more serious descriptor, compared with what level of function, what degree of disablement, and on what factual assumptions? Bano’s wider analysis supports the insistence that these hidden baselines be exposed, because a great deal of apparently sensible reasoning collapses as soon as the comparison point is made explicit.

It is also important to separate factual error from related but distinct legal complaints. Sometimes a decision really is built on a materially wrong factual premise: the condition began earlier than the decision accepts, the report said one thing and the summary says another, the evidence of functional restriction has been misstated, or the chronology has been misunderstood. In those cases the challenge may properly focus on factual mistake. But sometimes the problem is better analysed as failure to consider relevant evidence, failure to make adequate findings of fact, failure to explain why contrary evidence was rejected, or application of the wrong legal test. Bano’s method would not collapse these together. The important thing is to identify the actual hinge on which the decision turns and challenge that hinge precisely.

In practice, one of the commonest and strongest grounds of challenge is simply inadequate reasoning. A lot of bad decisions are not obviously irrational on their face. They are under-explained, overconfident and built on an account of the evidence so compressed that it is impossible to see how the conclusion was reached. This matters because the law does not merely require a result. It requires a decision-maker to identify the correct issue, engage with the material evidence, apply the correct legal test and explain why the conclusion follows. If a decision says only that the claimant does not meet the criteria, does not establish service causation, or does not warrant a higher tier or descriptor, that may not be enough. A carefully written assertion is still just an assertion if it does not reveal the reasoning.

The Ombudsman and complaint routes also matter, but they need to be understood properly. The Pensions Ombudsman is not a general appeal body for every disappointing outcome. It becomes relevant where pension disputes involve maladministration, failure to follow scheme rules or other pension-handling failures once the internal route has been exhausted. A Service Complaint is not usually the main route for arguing about the merits of a pension or compensation decision, but it may be relevant where the issue is unfair treatment, delay, failure to follow policy, procedural unfairness or mishandling within the service system. These routes are therefore part of a wider challenge strategy, not universal backup plans for everything that has gone wrong.

A good challenge, whatever route it uses, usually contains the same core elements. It identifies the decision being challenged. It explains what is wrong with it in specific terms. It identifies the evidence supporting the challenge, whether medical, functional, chronological, occupational or causation-based. It states the relevant legal or scheme test. It explains why the decision-maker’s reasoning fails, whether because the wrong facts were used, the wrong baseline adopted, the wrong legal test applied, the evidence ignored, or the reasons given are inadequate. And it states the remedy sought: review, revision, re-tiering, recognition of the same condition, tax-free treatment, a different descriptor, a fresh disablement assessment, or some other specific outcome. Without that structure, it is very easy to write something heartfelt and true that still does not land as an effective legal challenge.

This is why one of the most useful habits in this area is to separate the story from the ground of challenge. The story matters. It explains what happened, how the condition developed, and why the decision feels wrong. But in law the story alone is not usually the ground of challenge. The ground is more precise. The wrong condition was treated as operative. The same condition was wrongly treated as different. The chronology was misunderstood. The evidence was misread. The wrong legal test was applied. The reasoning was inadequate. The summary understated the medical reality. The baseline was false. Bano’s wider contribution is to insist that these be distinguished. Once they are, the challenge becomes much clearer.

The practical bottom line is that an official decision is not correct merely because it is written calmly and arranged in numbered paragraphs. The real question is whether it identifies the right issue, applies the right test, engages with the real evidence, and explains why the conclusion follows. Challenging a pension or compensation decision is not just arguing that the outcome feels wrong. It is identifying the exact point at which the facts, the legal analysis or the reasoning went off the rails, and then forcing the system to answer that point properly.

The technical legal issues hiding behind PIC disputes

 

Most PIC disputes look, at first, like arguments about diagnosis or medical wording. Often they are. But as soon as you follow the PIC into pension, compensation, review and appeal territory, a deeper set of legal questions appears underneath. These include burden of proof, causation, disablement, descriptors, review powers, overlapping schemes, and whether the system is even asking the right question about the same underlying condition. This section draws out some of those more technical issues. It is not here to turn the guide into a textbook. It is here because many PIC cases are lost not on the medical facts alone, but on the legal machinery built around them.

 

(a) WPS proof rules: why the burden can matter as much as the diagnosis

One of the most important legal features of the War Pension Scheme is that the argument is not always fought on the same proof terrain as a modern compensation claim. That matters in PIC cases because a dispute about the recorded discharge condition is often also a dispute about service attribution. Once the argument becomes “what was the real condition?” it very quickly becomes “was that condition due to service?” Under WPS, the answer to that second question can be shaped not just by the medical evidence, but by the legal burden and standard of proof.

 

This is one reason WPS can be more favourable to claimants than AFCS. In the relevant class of WPS case, once a proper service-attribution issue is raised, the Secretary of State may bear a heavy burden to disprove attribution. In other words, the veteran is not always required to build the whole causation case from nothing and carry it uphill alone. That does not mean every WPS case wins, and it does not mean the burden shifts automatically in every dispute. But it does mean that the legal treatment of doubt can be materially more helpful to the claimant than in descriptor-led AFCS decision-making.

 

That matters directly to PIC disputes. If the PIC, or the surrounding medical board material, clearly identifies the discharge-causing condition and places it within a service chronology, that may be powerful evidence in a WPS claim. It may help show what the condition was, when it arose, and why service attribution should not lightly be rejected. A strong PIC does not just help with diagnosis. In a WPS case, it may help establish the factual platform from which the burden question becomes important.

 

The reverse is also true. A weak PIC can damage the case by making the condition sound vague, non-specific or detached from service. If a traumatic spinal injury is reduced to “back pain,” or a serious psychiatric presentation to “low mood,” the department may later try to argue that the real service story was never properly established. But WPS can still sometimes be more forgiving of that weakness than AFCS, because the legal framework is not always as hostile to uncertainty. If the evidence as a whole still raises a real attribution issue, the claimant may have more room to recover than they would under a more rigid descriptor structure.

 

This is especially important where the medical aetiology is uncertain. Some conditions do not arrive with perfect explanatory labels. Symptoms may appear before the diagnosis is clear. Specialists may disagree. The mechanism may be medically complex. In that situation, WPS law does not simply allow the decision-maker to shrug and say that causation is uncertain, so the claimant loses. The legal treatment of uncertainty matters. A claimant does not necessarily fail just because medicine cannot explain every step with precision. That is one of the reasons the burden and standard of proof rules are so significant in this field.

 

The practical lesson is simple. In a WPS-linked PIC case, do not think only in terms of whether the diagnosis was recorded perfectly. Ask also whether the evidence is sufficient to raise the real service-attribution issue in a way that engages the claimant-friendly proof structure. A good PIC helps because it makes the condition and chronology harder to dilute. A bad PIC can still cause trouble, but it is not always fatal if the surrounding records, chronology and medical evidence still show the true condition with enough clarity.

 

So when a WPS case turns on the PIC, the legal question is often not just “was the label right?” It is also “has the evidence been analysed using the right proof rules?” That can make the difference between a case being treated as a vague medical disagreement and being treated as a war pension claim in which the state must do more than simply point to uncertainty and call that an answer.

 

(b) PICs and legal causation: diagnosis, aggravation and predominant cause

One of the easiest mistakes in this area is to assume that once the diagnosis is identified, the causation question more or less answers itself. It does not. A PIC may tell you what condition the system says ended service, but it does not by itself decide why that condition arose, whether service caused it, whether service materially worsened it, or how the law should treat competing causes. In Bano’s terms, diagnosis and causation are related, but they are not the same question.

 

This matters because many PIC disputes are really causation disputes wearing diagnostic clothing. On paper the argument may appear to be about whether the correct label was “back pain” or “lumbar disc prolapse with radiculopathy,” “low mood” or “service-related depressive disorder,” “knee pain” or “traumatic degenerative knee injury.” But the reason that wording matters is often that it changes the causation analysis underneath. A bland or generic label can make a service-related condition look medically untethered, while a more accurate description may reveal the service event, progression or mechanism that links the condition to service.

 

The first point is that service causation is a legal question as well as a medical one. Doctors help identify diagnosis, mechanism, prognosis and likely contribution. But the legal system still has to decide whether the condition is attributable to service, whether service materially aggravated it, or under AFCS whether service was the predominant cause in the relevant sense. That is why a case can go wrong even where the medicine is broadly accepted. The legal test may have been framed incorrectly or applied too narrowly.

 

Aggravation is particularly important in PIC cases. Not every valid case involves a condition caused wholly from scratch by service. Some conditions pre-exist service, emerge from an underlying vulnerability, or begin in relatively minor form and are then materially worsened by service demands, training, trauma, deployment or occupational strain. A decision-maker who treats causation as an all-or-nothing question may therefore miss a substantial part of the law. The proper question may not be “did service create this condition out of nothing?” but “did service make it materially worse, accelerate it, or turn a manageable condition into the one that actually ended service?”

 

This is where pre-existing vulnerability needs careful handling. A predisposition does not automatically defeat service causation. The fact that someone was vulnerable to injury, degeneration or psychiatric illness does not mean service played no legally relevant role. In many cases the question is whether service acted on that vulnerability in a way that caused the disabling condition to emerge, worsen or become career-ending. Bano’s analysis is helpful here because it resists the lazy slide from “there was a predisposition” to “therefore service is not responsible.” That is not a complete legal answer.

 

Under AFCS, the language often becomes more structured because the scheme asks whether service was the predominant cause in the way required by the statutory framework. That can make causation arguments feel sharper and more technical. It is not enough merely to say that service was one background factor among many. But that does not mean every multi-factor case is doomed. It means the evidence and argument need to identify clearly how service fits within the causal picture, what role it played, and why the condition should properly be treated as service-caused or service-aggravated in the legal sense. A weak PIC can be especially damaging here because descriptor-based reasoning works badly if the underlying causal story has already been flattened.

 

In WPS, the atmosphere may be more claimant-friendly on proof, but the same need for clear causation analysis remains. The question is still not simply what the diagnosis was, but whether the disablement is attributable to service or materially influenced by it in the way the scheme recognises. That is why the PIC matters so much. If the PIC captures the real service-related condition, it may preserve the causal story. If it strips the condition down to a symptom or a generic phrase, it may weaken the visible connection between service events and the eventual discharge.

 

Some PIC cases also involve more than one causal strand. There may be one principal condition recorded at discharge, but several service-related mechanisms feeding into it. A knee may have been damaged in one incident and worsened by repeated physical demands afterward. A psychiatric condition may reflect a mixture of operational trauma, cumulative stress and later deterioration. A spinal condition may involve one original injury, continuing load-bearing and subsequent neurological progression. In such cases, the legal mistake is often to isolate one neat moment and ignore the broader service contribution. The fact that causation is complex does not mean it disappears.

 

The practical lesson is that causation evidence should be built deliberately and not left to implication. It should address service events, timing, mechanism, aggravation, progression and the role of any pre-existing condition. It should explain whether later deterioration is part of the same service-related pathology or something genuinely separate. And it should make clear why the recorded PIC either does or does not reflect the real causal history.

 

So the right question is rarely just “what is the diagnosis?” In a PIC case the deeper legal question is usually something like this: what condition ended service, how did it develop, what role did service play in causing or worsening it, and has the official wording preserved that causal story or quietly erased it?

 

(c) Diagnosis is not disablement: why labels do not decide the case

One of the most common mistakes in pension and compensation disputes is to treat diagnosis as if it settles everything. It does not. A diagnosis tells you what condition someone has, or what clinicians think the condition is. It does not by itself tell you how far that condition disables them, how it affects military function, how it affects civilian employability, or how it should be assessed under a pension or compensation scheme. In PIC cases, that distinction matters enormously, because a recorded label can look neat on paper while saying very little about what actually ended service.

 

This is one of the key places where Bano’s legal framework is especially useful. The law often has to distinguish between the injury or illness itself and the disablement resulting from it. Those are related, but not interchangeable. A veteran may have a relatively familiar diagnosis with devastating functional consequences, or a medically imprecise label attached to a condition that has plainly destroyed military capacity. If the system focuses too much on the label and not enough on the disablement, it can make a serious case look trivial.

 

That is why a generic or flattened PIC can be so dangerous. Terms like “back pain,” “low mood,” “knee pain,” “hearing problems,” or “functional symptoms” may be medically true at a certain level of abstraction, but they often say almost nothing about severity, mechanism, prognosis or actual loss of function. A label of that kind may hide what the condition really did: inability to deploy, inability to carry weight, inability to sit or stand for sustained periods, cognitive fatigue, chronic pain flare-ups, panic symptoms, sleep disruption, medication effects, safety concerns, or the collapse of sustained work capacity. The legal problem is not just bad wording. It is that a weak label can distort the later assessment of disablement.

 

This matters particularly under WPS, where the legal focus often falls heavily on disablement due to service rather than purely on diagnostic neatness. A PIC may identify the principal condition, but the decision-maker still has to ask what disablement results from it. If the condition has been described too narrowly or too blandly, the disablement picture may be understated from the beginning. A veteran with a service-related spinal injury may end up looking, on paper, like someone with generic back discomfort. A serious psychiatric condition may be flattened into a mood label that obscures risk, cognitive effect and occupational collapse. Once that happens, later percentage assessment, review and appeal can all be skewed by the original understatement.

 

The same issue appears differently in AFCS. There, the system is more descriptor-led, but labels still do not decide the case on their own. The decision-maker must still identify the real injury or illness and assess its consequences within the legal structure of the scheme. If the wrong label is used, the wrong descriptor may follow. If the condition is under-described, its real functional impact may never be properly matched to the tariff framework. So even in a more categorised system, diagnosis does not eliminate the need to examine disablement and real-world effect.

 

The distinction also matters where there is more than one condition. The PIC identifies the principal invaliding condition, but the overall disablement picture may involve interacting conditions, secondary consequences, or overlapping symptoms. A spinal injury may coexist with chronic pain syndrome, depression, disturbed sleep and neurological symptoms. A knee injury may produce altered gait, back pain and functional collapse beyond the knee itself. A psychiatric condition may overlap with substance misuse, cognitive impairment or social withdrawal. The fact that one condition is selected as the PIC does not mean the rest of the disablement picture disappears. Bano’s approach is useful here because it resists treating the principal label as the whole legal story.

 

This is also why functional evidence matters so much. If diagnosis is only the starting point, the case needs evidence showing what the condition actually does. How does it affect military duties, attendance, deployability, concentration, stamina, pain tolerance, risk, sleep, movement, daily living and later employability? Can the person sustain activity, or only perform it briefly and then pay for it afterward? What adaptations were needed? What restrictions were imposed? These questions go directly to disablement, and often they are more legally significant than a tidy label.

 

A related problem arises when later, more precise diagnostic language appears. Decision-makers sometimes treat that as though it means the claimant has changed conditions. But a later and better diagnosis may simply be a more accurate description of the same disabling condition that was previously recorded in a vague way. “Back pain” may later become “lumbar disc prolapse with radiculopathy.” “Low mood” may later become “trauma-related depressive and anxiety disorder.” “Knee pain” may later become “traumatic degenerative knee pathology.” The important legal question is not whether the words changed. It is whether the disablement and underlying condition remained the same.

 

The practical lesson is simple. In a PIC case, do not ask only whether the label is technically defensible. Ask whether it captures the disablement that actually ended service. If it does not, the case may already have been distorted before the pension or compensation analysis even begins. The task is not just to prove a diagnosis. It is to show what the condition really did, why that mattered in service, and why a neat administrative label should not be allowed to replace the real disablement picture.

 

(d) When the summary is weaker than the report

One of the most common ways a good medical case turns into a bad legal decision is surprisingly simple: the underlying report is not the real problem, but the summary of it is. A consultant may describe serious symptoms, clear functional loss, sustained deterioration, service chronology and a diagnosis that fits the veteran’s account. Then, somewhere downstream, the official summary compresses all of that into something safer, vaguer and much less useful. A complex spinal case becomes “back pain.” A detailed psychiatric assessment becomes “low mood.” A report describing serious occupational collapse becomes a sentence saying the claimant has some ongoing symptoms but retains general function. By the time the decision is made, the paper trail looks thinner than the evidence ever was.

 

This matters because many pension and compensation decisions are not made from raw medical notes alone. They are made from summaries, recommendations, extracts and condensed accounts of what the medical evidence supposedly shows. Bano’s wider approach is especially useful here because it keeps returning to the same warning: a decision-maker has to engage with the actual evidence, apply the correct legal test and give reasons that explain how the conclusion was reached. If the summary materially weakens the report, that may not be a minor administrative imperfection. It may go directly to the lawfulness of the decision.

 

In PIC cases, this problem can be especially damaging because the summary is often where the flattening begins. A detailed medical history may support the argument that the real discharge-causing condition was more specific, more serious, more service-linked or more functionally destructive than the PIC wording suggests. But if the summary strips out chronology, mechanism, functional effect or diagnostic precision, later readers may assume the case was always weak. The issue is no longer just what the medicine said. It is what the system chose to carry forward from it.

 

This is why it is so important to compare the underlying material with the official account. If a report says the claimant has marked pain, severe mobility restriction, disrupted sleep, neurological symptoms and inability to sustain work activity, but the decision letter says only that there is evidence of discomfort and some limitation, the problem is visible. If a psychiatric report describes trauma symptoms, functional breakdown, poor concentration, risk and chronic occupational impact, but the downstream summary records only low mood and stress, the distortion is visible. If the medical board material records serious restrictions and the later pension or compensation decision treats the condition as mild, the distortion is visible. These comparisons can be powerful because they show not merely disagreement, but shrinkage.

 

The legal significance of this will vary depending on the route of challenge. Sometimes the point will be that the decision-maker made a material mistake of fact. Sometimes it will be that relevant evidence was not properly considered. Sometimes the stronger argument will be failure to make adequate findings of fact, failure to give sufficient reasons, or application of the wrong legal test to an under-described factual picture. Bano’s method is particularly helpful here because it discourages the lazy habit of labelling every evidential problem the same way. The important thing is to identify what exactly went wrong in the decision-making process.

 

Missing records can create a related but distinct problem. In some cases the evidence is not merely weakened in summary but partly absent from the official chain. Bano’s analysis helps here too. Missing records do not automatically make the claimant lose, and they do not entitle the decision-maker to fall back on a neat conclusion unsupported by the available evidence. If official records are incomplete, the task of fair fact-finding becomes more important, not less. The decision-maker still has to engage with what is available, explain how findings are reached and avoid treating absence of paperwork as if it were proof that nothing happened.

 

This issue is especially acute where the system is sceptical of a diagnosis or reluctant to recognise its full implications. A condition may be accepted clinically but softened administratively. Or a diagnosis may be treated with suspicion because the terminology evolved over time, because specialists used different language, or because the official preference is for a safer and less consequential label. Once again, the answer is not just to say the department is being unfair. It is to show, document by document, how the stronger evidence has been thinned out.

 

Practically, this means one of the most useful things a claimant can do is build a short comparison exercise. Put the full report, the summary and the decision side by side. Ask what has disappeared. Has severity disappeared? Has chronology disappeared? Has service context disappeared? Has functional loss disappeared? Has the specific diagnosis become a symptom label? Has a condition affecting employment become a condition producing only “some limitations”? This sort of comparison often does more than pages of indignation because it reveals the mechanism by which the case was weakened.

 

So when the summary is weaker than the report, the problem is not just style. It may be the place where a legally strong case was quietly turned into an administratively easier one. In PIC disputes, that matters enormously, because once the wrong summary becomes the working version of the facts, every later decision may inherit the same distortion.

 

(e) Review, revision and appeal: different routes for different errors

One of the easiest ways to lose a good case is to use the wrong route for the wrong problem. In PIC disputes, that happens all the time. A claimant may say the original decision was wrong, when the real issue is later deterioration. Or they may say the condition has worsened, when the real problem is that the original decision misunderstood the condition from the start. They may ask a tribunal to correct something that properly belongs in an internal review process, or treat a review as if it were a full appeal on every issue. Bano’s wider treatment of these systems shows why this matters: pension and compensation law is not just about whether the facts are sympathetic. It is also about which legal mechanism is available to correct which kind of error.

 

The first distinction is between an original wrong decision and a later change in circumstances. These are not the same thing. Sometimes the case is that the decision-maker got it wrong at the time because the PIC was misidentified, the condition was under-described, the wrong legal test was used, or relevant evidence was not properly understood. That is an original error case. But sometimes the original decision may have been broadly defensible on the material then available, and the real complaint is that the condition has since deteriorated beyond what was recognised. That is a different type of case. The evidence, the route and the remedy may all differ.

 

This distinction matters particularly in PIC cases because later evidence often does two jobs at once. A later consultant report may show that the claimant is worse now, but it may also show that the original description was wrong all along. A later diagnosis may indicate deterioration, or it may simply be a better account of the same condition that caused discharge. A claimant therefore needs to ask: am I saying the original decision was wrong when made, or am I saying the condition has materially changed since then? Those are related arguments, but they are not interchangeable.

 

Reviews and revisions are often the route where original error issues are raised within the scheme structure. The argument here may be that the decision was made in ignorance of a material fact, involved a mistake of fact or law, misapplied the rules, or misunderstood the condition that actually ended service. In a PIC context, that can include cases where the wrong condition was treated as the operative one, where the system split one underlying condition into several different labels, or where the decision rested on a summary that materially understated the underlying medical evidence. The point of this kind of challenge is not merely that the outcome now feels unfair. It is that the decision was flawed at source.

 

Deterioration cases are different. Here the argument is not necessarily that the original decision-maker made a legal or factual error on the material then available. The argument is that the condition has worsened, further consequences have emerged, function has declined, or a previously lower level of impairment has become more serious. That can matter greatly in both pension and compensation systems, but it is not the same as proving the original decision was wrong. Bano’s method is especially useful here because it forces discipline: if the claimant does not separate original error from later worsening, the challenge can become confused and easier to reject.

 

Appeals bring a further layer of complexity. An appeal body is not always being asked the same question as a reviewer. In some contexts, the appeal is concerned with whether the original decision was right on the facts and law as they stood at the time it was made. That means later evidence may be relevant only insofar as it sheds light on the original position, rather than because it proves later deterioration in its own right. This is one of the reasons PIC cases can become technically difficult. A later diagnosis, for example, may be powerful evidence if it shows that the original PIC was merely a vague label for the same condition. But it may be less useful if it is being relied on only to show a later worsening that was not part of the original decision.

 

There is also a tactical point here. Challenging a decision can carry risk if the review or revision power is capable of reopening issues more broadly than the claimant expects. That does not mean good cases should not be pursued. It means the claimant should be clear about what is being challenged, on what basis, and what outcome is actually sought. In some systems, asking for the wrong kind of reconsideration without a clear theory of the case can create unnecessary exposure or confusion. Bano’s approach encourages exactly the opposite: disciplined identification of the issue, the route, the evidence and the remedy.

 

This is why the framing of the challenge matters so much. “My condition is worse” is not the same as “the original decision used the wrong PIC.” “The later diagnosis is more serious” is not the same as “the earlier wording was a vague description of the same underlying pathology.” “The award is too low” is not the same as “the decision-maker applied the wrong legal test or failed to engage with the functional evidence.” These differences may sound technical, but they often determine whether the case is being argued in a legally workable form.

 

The practical lesson is simple. Before challenging a decision, identify the kind of error you are alleging. Is it a wrong original diagnosis or description? A mistake of fact? A mistake of law? Failure to consider relevant evidence? Inadequate reasons? Or genuine later deterioration? Once that is clear, the route becomes easier to identify and the evidence can be organised properly around it. In PIC cases, the facts may be medically continuous, but the legal routes are not. The claimant has to know whether they are trying to prove that the system got the case wrong at the start, failed to revise it when it should have done, or is now refusing to recognise a later worsening of the same condition.

 

(f) AFCS descriptors still depend on identifying the real injury

One of the attractions of the Armed Forces Compensation Scheme is that it looks structured. Injuries and illnesses are matched to descriptors, descriptors lead to tariff levels, and the whole exercise appears cleaner than the older world of war pensions. But that apparent neatness can be misleading. A descriptor does not remove the need to identify the real injury or illness properly. On the contrary, the descriptor exercise depends on getting that first step right. If the starting description is wrong, flattened or incomplete, the rest of the analysis may be tidy and still be wrong.

 

This is why PIC wording can be especially important in AFCS cases. A weak or generic PIC may not just be a poor medical label. It may distort the entire descriptor exercise from the beginning. If the condition that ended service is recorded only as “back pain,” “knee pain,” “low mood,” or some other safe administrative shorthand, the later compensation decision may start from an under-described version of the injury. Once that happens, the scheme may ask the wrong legal question, match the wrong descriptor, or underestimate the seriousness of the condition’s functional consequences.

 

Bano’s broader analysis helps here because it shows that AFCS is not simply a coding exercise. The legal structure may be descriptor-led, but the decision-maker still has to identify the underlying injury or illness, understand its consequences and apply the causation test properly. This means there is no shortcut from vague wording to lawful conclusion. A descriptor can only be as sound as the injury identification on which it rests.

 

This becomes particularly important where the injury evolves over time. Some conditions do not present in their final form at the moment of discharge or claim. A spinal injury may begin as back pain and later reveal disc pathology, nerve involvement and chronic functional restriction. A knee injury may begin with instability and later produce degenerative change, surgery and long-term loss of function. A psychiatric injury may first appear as stress or low mood and later be understood as trauma-related illness with substantial occupational consequences. In cases like these, the legal question is not simply what label appeared first. It is what injury the claimant in fact suffered and how its trajectory should be understood within the scheme.

 

That is why later treatment, complications and progression may matter. The proper descriptor may depend not just on the initial presentation, but on the real nature of the injury and its consequences as they become medically clear. A later operation, persistent neurological deficit, serious deterioration or complex pattern of symptoms may show that the earlier, flatter description never captured the actual injury. In that sense, the trajectory of the condition matters. The scheme is not supposed to reward the neatest early shorthand. It is supposed to assess the injury that was actually sustained.

 

Functional limitation is also central. AFCS may use descriptors and tariffs, but it still requires a serious look at what the injury does. A decision that identifies the condition in a medically thin or generic way may then underestimate the degree of functional restriction that flows from it. This is especially dangerous where the decision-maker confuses theoretical capacity with real-world function. A claimant may be able to perform a task briefly and still be unable to sustain full-time work, military duties or ordinary daily activity in any reliable way. If the real functional picture is not linked back to the real injury, descriptor reasoning can become overly abstract.

 

This is also where caution is needed in comparing AFCS with pension or WPS reasoning. The fact that a condition attracts a particular disablement assessment under one framework does not mechanically determine the right AFCS descriptor under another. They are different legal exercises. But that difference cuts both ways. The AFCS decision-maker cannot simply rely on the scheme’s tidy structure and ignore the deeper medical reality. A tariff framework is not a substitute for proper factual identification.

 

The practical lesson is that AFCS cases should never be argued as if the descriptor table does all the work by itself. The first argument is still about the real injury. What condition was actually sustained? Was the original PIC or summary merely a vague symptom label for something more specific? Has later evidence clarified the same underlying injury rather than revealed a new one? What functional limitations truly flow from that injury? Only once those questions are answered properly does the descriptor exercise become legally trustworthy.

 

So although AFCS looks more modern and orderly than WPS, it is still vulnerable to the oldest problem in this field: beginning with the wrong description of the condition. If the real injury is not identified accurately, the scheme may produce a precise tariff answer to the wrong question.

 

(g) Overlap cases: same condition, different schemes, and no free double recovery

Some of the hardest PIC disputes are not hard because the medicine is obscure, but because the legal systems overlap. A condition may begin before 6 April 2005, worsen afterward, lead to discharge under a later pension framework, and then generate compensation questions under a scheme that asks slightly different questions again. That is where one medical story can suddenly find itself being examined through several different legal lenses. Bano’s treatment is especially useful here because it shows that overlap cases are not just messy in narrative terms. They raise real legal questions about classification, causation, entitlement and the relationship between schemes.

 

The first point is that one broad medical history can produce consequences in more than one legal framework. The pension side may depend on one set of scheme rules. Compensation may depend on another. A claimant may therefore feel that the same condition is being looked at repeatedly but differently. That impression is often correct. The mistake is to think that this means the claimant can simply choose whichever version is most favourable in each system without legal constraint. Overlap does not create a free right to duplicate recovery for the same injury under different labels.

 

That is why the “same condition” question matters so much. The law may need to ask whether two different descriptions are really the same underlying injury, whether later deterioration is part of the same condition or a separate one, whether aggravation after the scheme boundary is legally distinct from the earlier pathology, and whether pension and compensation are in substance talking about the same disablement. In PIC cases, this often becomes the central argument. A later diagnosis may look new on paper while actually being a more specific description of the same discharge-causing condition. Equally, some later developments may genuinely be separate enough to require different legal treatment. The answer cannot be assumed from the wording alone.

This matters because overlap can affect not just route but value. Where the law treats two awards as relating to the same injury or condition, that may have consequences for offset, abatement or other restrictions designed to prevent double recovery for the same loss. The point is not that a claimant should avoid showing that the same condition runs through pension and compensation. Often that consistency is essential. The point is that consistency may bring both advantages and disadvantages. It may support attribution, coherence and tax arguments, while also affecting how different payments interact.

 

The problem becomes especially sharp in spanning cases. An injury may originate before the 6 April 2005 boundary, continue through it, and later be assessed in a world where WPS, AFCS and pension rules no longer align neatly. The veteran may understandably say that it is one damaged knee, one damaged spine or one psychiatric condition. The legal systems may then ask whether the relevant loss before and after the boundary is the same injury, the same disablement, an aggravation of the same condition, or a new and separate consequence. Bano’s approach helps here because it insists on careful analysis of chronology, pathology and legal consequence rather than rhetorical shortcuts.

 

This is one reason chronology and medical continuity matter so much. If the claimant can show that the later diagnosis is simply a fuller description of the earlier service-related condition, that may help preserve one coherent medical story across the schemes. If the evidence instead shows a genuinely new pathology, a later supervening cause, or a separate condition with a distinct legal history, the analysis may look different. In either case, the task is to identify what is truly the same and what is truly different. That is a legal exercise built on medical facts, not just an administrative naming dispute.

 

The PIC can be crucial here because it may be the earliest formal statement of the principal discharge-causing condition. If it is accurate, it can anchor continuity across multiple systems. If it is weak, generic or misleading, later decision-makers may find it easier to split one medical story into several boxes. A spinal injury becomes back pain, then musculoskeletal symptoms, then degenerative disease, then neurological impairment. A psychiatric condition becomes stress, then adjustment disorder, then depression, then functional breakdown. Once the language fragments, the legal analysis may fragment with it.

 

The practical lesson is that overlap cases need to be argued with two ideas in mind at the same time. First, preserve the continuity of the underlying condition where that continuity is real. Second, do not assume that continuity means every scheme can pay freely and independently for the same loss. The claimant has to show both the medical coherence of the case and an understanding of the legal consequences of sameness. That includes route, classification, timing and possible interaction between awards.

So the problem in overlap cases is not simply that the facts are complicated. It is that one condition may have to survive several legal systems, each asking slightly different questions and each potentially reacting differently if it concludes that the claimant is really being compensated twice for the same injury. The aim is therefore not just to prove continuity, but to prove it with enough precision that the law can recognise the same condition without collapsing into confusion or duplication.

 

(h) What a PIC claim may cover — and what it may not

One of the quiet difficulties in PIC cases is that claimants often do not know how broadly or narrowly their claim will be treated. They may assume that if they identify the principal condition, the system will automatically deal with everything flowing from it. Or they may assume the opposite: that unless every consequence is separately named from the beginning, the law will ignore it. Both assumptions can cause problems. Bano’s treatment is useful here because it shows that the scope of a claim is a legal question in its own right. It is not determined simply by what the claimant happened to call the condition in ordinary language.

 

The starting point is that a PIC is not the same thing as the entire claim. The PIC identifies the principal invaliding condition for discharge purposes. But once pension or compensation decisions are being made, the law may need to consider related consequences, secondary conditions, progression, overlapping symptoms or more precise diagnostic descriptions. The important question is whether those later or associated features are part of the same underlying injury or illness, or whether they are legally distinct matters requiring separate treatment.

 

That is why a later, fuller diagnosis does not necessarily fall outside the original claim. If the claimant originally appears to have been discharged for “back pain,” but later evidence shows lumbar disc injury with radiculopathy, the issue may not be that a new claim is required. The better analysis may be that the original claim always concerned the same underlying spinal condition, and the later terminology merely describes it more accurately. The same may apply where “low mood” becomes a trauma-related depressive disorder, or “knee pain” becomes traumatic degenerative knee pathology. In cases like these, the law is not always confined to the earliest and weakest label.

 

Equally, there are limits. A claim about one principal condition does not automatically and without analysis bring in every later medical difficulty the claimant experiences. Some later problems may be secondary consequences of the same condition. Some may be attributable associated conditions discovered in the course of examination. But some may be distinct enough that they need to be raised, evidenced or claimed separately. The fact that one condition was selected as the PIC does not give the claimant a blank cheque to treat every later symptom as already legally absorbed into the same case.

 

This is especially important where examination or review reveals additional attributable conditions. Sometimes the medical evidence uncovers more than the claimant initially appreciated. A person may claim for one obvious injury and later discover associated neurological, psychiatric or functional consequences. In some legal contexts, that does not mean the new material must be ignored simply because the claimant did not formulate it perfectly at the outset. The decision-maker may have to address the condition actually disclosed by the evidence, not just the narrowest wording used in the first piece of paperwork. Bano’s method is helpful here because it insists that legal analysis should respond to the real condition shown by the facts.

 

But that principle should not be overstated. The claimant still needs to be careful. If the case involves genuinely separate conditions, separate periods of causation, or later consequences not obviously part of the same injury history, it may be unsafe to assume that the original PIC dispute automatically covers them. This is one reason chronology and condition-mapping matter so much. The claimant needs to be able to say what is part of the same underlying pathology, what is a secondary consequence, what is aggravation, and what is genuinely distinct.

 

The practical importance of this is obvious in evidence and submissions. A good PIC-based argument should make clear whether the claimant is saying:

• the later diagnosis is a fuller description of the same condition;
• the later symptom is a consequence of the same condition;
• the associated condition was always part of the same service-related picture;
• or there is an additional distinct condition which also requires recognition.

Without that clarity, decision-makers may choose the narrowest available interpretation and say the issue was never properly before them.

 

This is also where claimants need to be realistic about the limits of principal-condition reasoning. The fact that a condition is the PIC does not mean every legal consequence follows automatically. Tax treatment, tiering, descriptor choice, disablement level and overlap with compensation rules may all still require separate analysis. The PIC may anchor the case, but it does not finish it.

 

So the safest way to think about scope is this: a PIC claim may cover more than the shortest label first suggests, especially where later evidence shows the same underlying condition more clearly. But it may also cover less than the claimant hopes if separate conditions or separate legal consequences are simply assumed rather than properly identified. The task is therefore to define the claim by medical and legal continuity, not by administrative shorthand and not by wishful expansion.
