This landmark batch of appeals brought by the Union of India challenged various orders passed by the Armed Forces Tribunal (AFT) and High Courts, which had granted the disability element of service pensions to ex-servicemen. These former personnel had been assessed by Release Medical Boards (RMB) as having disabilities that were “Neither Attributable Nor Aggravated” (NANA) by military service. The Supreme Court addressed the core tension between the protective, beneficial jurisprudence established in Dharamvir Singh v. Union of India (governed by the Entitlement Rules 1982) and the restrictive framework introduced by the subsequent Entitlement Rules 2008. Crucially, the Court undertook a deep constitutional and administrative review of the legitimacy of the 2008 rules, evaluating whether they possessed binding legal force and whether they could dilute established beneficial entitlements.
- Distinction in Cessation of Service: The Court carefully clarified the legal boundary between actual “medical invalidation” (premature exit due to unfitness) and “normal retirement” on superannuation or completion of tenure, noting that both categories remain eligible for disability elements if the threshold criteria are fulfilled.
- The Validity of the Entitlement Rules 2008: Relying on findings from the 2015 Raksha Mantri Committee Report, the Supreme Court cast serious doubt on the legal sanctity of the Entitlement Rules 2008 and Pension Regulations 2008. The Court underscored that these documents were merely unverified compilations by the Defence Accounts Department that lacked mandatory Cabinet or Department of Pension and Pensioners’ Welfare (DoPPW) approval under the Allocation of Business Rules, 1961.
- Primacy of the 1982 Rules: The Court ruled that where regressive provisions in the 2008 compilation conflict with actual historical entitlements or negatively impact pensioner rights without due process, the Entitlement Rules 1982 and Pension Regulations 1961 shall continue to prevail.
- Reaffirmation of Dharamvir Singh: The foundational principles of Dharamvir Singh—including the statutory presumption of sound physical and mental health upon entry, the legal inference that deterioration during service is service-connected, and the assignment of the burden of proof strictly onto the employer—continue to hold the field.
- Final Disposition: The Supreme Court dismissed the appeals filed by the Union of India, heavily criticizing the systemic lodging of repetitive and delayed litigation against disabled ex-servicemen and reinforcing that the grant of a disability pension remains a rule built on welfare, with denial being a narrow exception.
