Direct answer
Disability pension ordinarily requires a qualifying disability attributable to or aggravated by military service. Invalid pension is a distinct benefit for eligible medical invalidment involving NANA disability, subject to its own conditions. The two terms are not interchangeable.
Legal position and important distinctions
Applying the historical minimum-service rule to every new invalid-pension claim can be wrong. DESW describes the order of 16 July 2020 removing the ten-year requirement for a specified category, with conditions concerning service on or after 4 January 2019 and permanent incapacity for military service as well as civil re-employment. NANA classification alone therefore does not automatically establish eligibility.
Separate three decisions
Diagnosis, the assessed impairment percentage and legal entitlement to pension are different enquiries. Identify which board or authority decides each question. A supporting medical certificate is not final pension sanction. Likewise, a low medical category does not necessarily establish permanent incapacity or inability to undertake civil employment.
Prepare an evidence-based appeal
Date enrolment, first diagnosis, treatment, boards, discharge and rejection. Link every disputed finding to a specific annexure and page. Where ER 2023 applies, examine the six-month first and second pension-appeal provisions from the relevant rejection or sanction letter. Administrative time-bar provisions and judicial condonation before the AFT are distinct. An RTI request or reminder should not cause the original deadline to be missed.
Choose the correct relief
Depending on the defect, seek recognition of entitlement, correct classification, fresh medical consideration, a corrigendum PPO or calculation correction. Reassessment and payment sanction are not necessarily the same decision. Explain the arrears period and interest basis separately.
Practical steps
- Identify the pension category actually decided.
- Check service dates, medical invalidment and permanent-incapacity evidence.
- If the wrong category was considered, seek a decision under the correct rule.
Documents to collect
- Invalidment and incapacity findings
- Commencement and end of service
- Pension claim and decision
Hypothetical illustration
A medically invalided member denied disability element for a non-service-related condition may still require separate consideration for invalid pension.
Avoid this mistake
Do not merge service pension, disability element and invalid-pension requirements into one assumed calculation.
