Psychiatric Disability Pension in Armed Forces 2026: Schizophrenia, Psychosis, Depression, NANA & AFT Remedy

For the general framework, see our Armed Forces disability pension guide. For a focused analysis of NANA findings, see Attributable or Aggravated by Military Service: NANA and AFT Challenge.

1. What counts as a psychiatric disability in Armed Forces pension cases?

Psychiatric disability claims can arise from a wide range of diagnoses, including schizophrenia, paranoid schizophrenia, schizoaffective disorder, unspecified non-organic psychosis, bipolar affective disorder, major depressive disorder, anxiety disorders, post-traumatic or stress-related disorders, adjustment disorders and other recognised psychiatric conditions.

The diagnosis alone does not determine pension entitlement. Pension law asks a separate question: whether the condition is attributable to or aggravated by military service under the governing entitlement framework, and whether the assessed disability percentage and service-exit category qualify for the relevant disability-related pensionary benefit.

2. Why psychiatric disability cases are legally difficult

Psychiatric conditions present distinctive evidentiary problems. Symptoms may fluctuate. There may be periods of apparent normal functioning. A predisposition may not have been detectable at enrolment. The service member may have difficulty identifying or articulating early symptoms, stressors or family history. In severe illness, cognitive impairment itself may affect the person’s ability to pursue representations or appeals.

This is why psychiatric cases cannot be decided by labels alone. The medical board must distinguish between diagnosis, cause, service connection and degree of disablement.

3. Supreme Court: Rajumon T.M. v. Union of India, 7 May 2025

Rajumon T.M. v. Union of India, 2025 INSC 644, is now one of the most important authorities in psychiatric disability-pension litigation. Rajumon had served more than nine years before being invalided out with schizophrenia. The Invaliding Medical Board assessed the disability at 30% for two years but treated it as constitutional and NANA.

The Supreme Court found that the relevant medical-board form required reasons, yet the board had not actually stated the reasons for concluding that the schizophrenia was constitutional and unrelated to service. The Court drew a clear distinction between a conclusion and the reasons supporting that conclusion.

The Court also recognised that schizophrenia can impair cognitive capacity and therefore affect a serviceman’s ability to properly advance his own case concerning the cause and circumstances of illness. It granted disability pension, while limiting arrears in the facts of that case.

4. Delhi High Court: Sgt Birendra Kumar, 29 January 2026

In Union of India v. Sgt Birendra Kumar (Retd.), the Delhi High Court examined an AFT order granting disability element for Paranoid Schizophrenia assessed at 40% for life and rounded to 50% for life. The Court relied heavily on Rajumon and emphasised the need for a more realistic approach in schizophrenia cases because the illness itself can create impediments in proving causal connection.

The decision reinforces that a psychiatric NANA finding cannot simply be accepted as conclusive where the medical reasoning is deficient. The focus is on whether the board has actually explained why the condition should be treated as non-service connected.

5. Jammu & Kashmir and Ladakh High Court: Ex Rfn Surinder Singh, 12 February 2026

In Union of India v. Ex Rfn Surinder Singh, the Release Medical Board had assessed schizophrenia at 40% for life but recorded NANA. The AFT granted disability element with rounding to 50% for life, and the High Court declined to interfere.

The Court observed that schizophrenia may arise from biological, psychological and environmental factors and that severe or chronic stress, trauma and isolation associated with service can potentially contribute to aggravation. It found the medical opinion vague and cryptic and held that the benefit of such ambiguity had to go to the veteran in that case.

6. Rajasthan High Court: Ex-Nk Achal Das, 8 April 2026

Ex-Nk Achal Das v. Union of India involved “Unspecified Non Organic Psychosis” assessed at 40% for life. The AFT had rejected disability element by relying on the proposition that certain mental disorders may escape detection at enrolment. The Rajasthan High Court disagreed on the facts.

The Court noted that there was no record that the disease existed prior to entry into service and that the medical record placed onset during service. It allowed the petition, directed treatment of the disability at 50% for computation and ordered release of disability pension from the date of the AFT application, with earlier period dealt with notionally.

7. Kerala High Court: Valsala S., 26 May 2026

In Union of India v. Valsala S., the Kerala High Court considered a long-delayed schizophrenia disability-pension claim pursued by the widow of a former serviceman. The AFT had found that the medical board’s description of schizophrenia as constitutional in origin was unsupported by reasoning.

The High Court referred to Rajumon, particularly its recognition that schizophrenia may impair cognitive ability and thereby affect the person’s capacity to pursue pension remedies. This authority is useful where delay and psychiatric incapacity are intertwined, although limitation and arrears must still be examined case by case.

8. Important caution: Ex Gdr Sher Singh shows that not every schizophrenia claim succeeds

A balanced legal guide must also account for adverse authority. In Ex Gdr Sher Singh v. Union of India, the Supreme Court on 4 December 2025 dismissed the appeal and upheld denial of disability pension after examining the detailed psychiatric report relied upon by the authorities. The Court found that the disability fell outside attributability/aggravation to military service on the record before it.

This matters because Rajumon is not a rule that every schizophrenia diagnosis must be treated as service related. Its central contribution is that medical opinions which determine valuable pension rights must be reasoned and supported. Where the medical record contains detailed, legally sustainable reasons demonstrating absence of service nexus, the result may be different.

9. What does “constitutional” or “predisposition” mean in psychiatric pension cases?

Medical boards sometimes describe schizophrenia or psychosis as constitutional, endogenous, genetic or arising from predisposition. Such terminology may be medically relevant, but it must be connected to the individual record. A label is not the same thing as proof.

A legally defensible medical opinion should ideally identify the factual and clinical basis for the conclusion: family psychiatric history, pre-service symptoms, documented personality or behavioural history, specialist findings, temporal relationship with service, and why service conditions did not materially trigger or aggravate the condition.

10. Peace station does not end the inquiry

The fact that onset occurred at a peace station may be relevant, but it is not necessarily decisive. Military service at a peace location can still involve long hours, isolation, command pressure, disciplinary stress, night duties, family separation, shift work and other stressors.

The real inquiry is not whether the location was labelled “peace” but whether the actual service conditions had a material relationship with onset or aggravation under the governing entitlement framework.

11. Schizophrenia and service stress

In psychiatric litigation, service stress should be proved factually rather than asserted abstractly. Relevant material can include:

• field, high-altitude, counter-insurgency or operational postings;
• prolonged isolation or family separation;
• traumatic incidents or exposure to casualties;
• night shifts and disrupted sleep;
• severe command or supervisory responsibilities;
• disciplinary or workplace stress occurring close to onset;
• documented behavioural change during a particular posting;
• psychiatric referrals showing chronology of symptoms.

12. What about schizoaffective disorder?

Schizoaffective disorder combines features of psychosis and mood disturbance. Pension entitlement must still be tested under the same basic structure: governing rule set, entry condition, onset, aggravation, specialist findings, medical-board reasoning, degree of disablement and category of release.

A board should not mechanically equate schizoaffective disorder with pre-existing constitutional disease unless the record supports that conclusion. Equally, the claimant should not assume that onset during service alone automatically establishes service connection under every version of the entitlement rules.

13. Depression and anxiety disability-pension claims

Major depressive disorder and anxiety disorders may present differently from schizophrenia. These cases often turn more directly on identifiable stressors, duration of symptoms, treatment history and functional impairment.

Where a medical board records NANA, the same principles of rationality apply: the board should identify why military service did not materially contribute, rather than merely describing the illness as personal, reactive or constitutional. Conversely, if non-service causes are clearly documented, those may support a NANA conclusion.

14. PTSD and trauma-related conditions

Post-traumatic and stress-related disorders require careful chronology. The central evidentiary question is often whether there is a clinically and temporally credible link between a service event or prolonged service exposure and the psychiatric condition.

Operational records, casualty exposure, incident reports, witness material, psychiatric notes and onset chronology may become particularly important. A generic service-profile statement is usually less persuasive than concrete evidence of the precipitating event or stress environment.

15. ER 2008 versus ER 2023

The official DESW FAQ states that under ER 2023, disability pension is available to personnel invalided or deemed invalided on medical grounds with disability held attributable to or aggravated by military service; personnel retained in service despite such disability and later retiring normally may fall under the impairment-relief framework.

16. Medical-board reasoning: what should be recorded?

For psychiatric disability, a reasoned medical-board opinion should ordinarily address:

1. diagnosis and diagnostic basis;
2. date and circumstances of onset;
3. entry medical status;
4. pre-service psychiatric or behavioural history, if any;
5. family psychiatric history where relevant;
6. service postings and identified stressors;
7. whether service caused, precipitated or aggravated the condition;
8. why the condition is or is not considered constitutional/endogenous;
9. percentage and duration of disablement;
10. functional limitations and treatment history.

17. When is a psychiatric NANA finding vulnerable?

A psychiatric NANA opinion may warrant challenge where:

• the board merely writes “constitutional” or “not connected with service” without reasons;
• the individual was accepted fit at entry and the board does not explain pre-existing disease;
• onset occurred after substantial service but the service history is ignored;
• documented service stress is not addressed;
• the specialist note and final board conclusion materially conflict;
• the appellate authority merely reproduces the medical-board conclusion;
• the wrong entitlement rule or medical guide was applied;
• the board does not distinguish predisposition from actual causation/aggravation.

18. When may NANA be legally defensible?

Not every psychiatric NANA finding is defective. A denial may be more sustainable where a detailed specialist record identifies a convincing non-service cause, documents pre-service or independent psychiatric pathology, explains why military conditions did not materially contribute, and applies the correct entitlement rules.

Ex Gdr Sher Singh is an important reminder that courts may uphold denial where the psychiatric medical record is detailed and supports absence of service nexus.

19. Invaliding Medical Board versus Release Medical Board

Psychiatric cases may arise through medical invaliding before completion of service or through a Release Medical Board at normal retirement/discharge. This distinction matters because the pension category and applicable rules may differ.

Where a member is invalided out, the invaliding condition and service connection are central. Where the member is retained and later retires, the claim may involve disability element under the earlier framework or impairment relief under ER 2023, depending on the date and circumstances.

20. Psychiatric disability percentage and broad-banding

Psychiatric disabilities are often assessed at 20%, 30%, 40%, 60% or higher, depending on diagnosis, functional effect and duration. Where entitlement is established, broad-banding or rounding-off may apply under the governing law.

For example, recent cases involving schizophrenia at 40% have resulted in computation at 50% where broad-banding was otherwise legally applicable. But broad-banding is a calculation issue; it does not by itself establish service connection.

For the broader arrears position, see Sgt Girish Kumar: disability pension arrears and broad-banding.

21. Psychiatric disability and delay in filing

Delay issues should be treated carefully in psychiatric cases. Rajumon expressly recognised that schizophrenia can impair cognitive ability and thereby affect the person’s capacity to properly advance a claim. That does not abolish limitation, but it can be a relevant fact when explaining delay, especially where incapacity is medically documented.

A proper delay application should therefore link the psychiatric condition to the actual procedural delay rather than rely on diagnosis alone.

22. Departmental First Appeal and Second Appeal

A psychiatric disability appeal should be structured around the medical record. Useful points include:

• the exact diagnosis and percentage;
• entry medical fitness;
• date of onset and psychiatric referral;
• service posting immediately before onset;
• specific stressors or traumatic events;
• reasons given—or not given—by the medical board;
• contradictions between specialist opinion and final NANA classification;
• applicable ER/GMO provisions;
• why a constitutional/predisposition label is unsupported on the individual record.

25. Frequently asked questions

Does schizophrenia automatically qualify for disability pension?

No. Entitlement depends on the applicable rules and facts. But a NANA opinion that simply calls schizophrenia constitutional without giving reasons may be vulnerable after Rajumon.

Can schizophrenia be aggravated by military service?

Yes, depending on evidence. Courts have recognised that severe or chronic stress, trauma and isolation may be relevant aggravating factors. The actual service record remains critical.

What if the medical board says the disease was constitutional?

The board should identify the medical and factual basis for that conclusion. A bare label without supporting reasons may not be sufficient.

Does onset in a peace station defeat a psychiatric claim?

No, not automatically. The actual duties, stressors, environment and medical chronology must still be examined under the governing rules.

Can depression or anxiety qualify?

Potentially, yes. The claim depends on diagnosis, functional impairment, service nexus, percentage and applicable pension rules.

Can a 40% psychiatric disability be rounded to 50%?

Where entitlement is established and the broad-banding framework applies, 40% may be reckoned as 50% for pension computation.

Can psychiatric illness explain delay in filing?

It can be relevant, particularly where medical evidence shows impaired cognitive or functional capacity, but it does not automatically remove limitation requirements.

26. Key takeaway

Psychiatric disability-pension litigation is strongest when it avoids two extremes: assuming that every mental illness must be service connected, or assuming that schizophrenia/psychosis is automatically constitutional and NANA. The lawful approach is evidence-driven and rule-specific.

Rajumon T.M. has made one principle especially important: where a serviceman’s discharge and pension rights depend on a medical opinion, the opinion must be supported by proper reasons. The 2026 High Court cases show that this principle is now having significant practical effect across schizophrenia and psychosis claims.
