As per case facts, the Union of India appealed judgments regarding condonation of service shortfall for Defence Security Corps (DSC) personnel to receive a second pension. Appellants argued that DSC ... personnel drawing pension from the Regular Army were not eligible for condonation, citing specific regulations and a Ministry of Defence letter barring it. Respondents contended that general pensionary provisions, including condonation, applied to DSC personnel unless explicitly inconsistent, and previous similar prohibitory letters had been struck down by courts. They also sought service rounding off. The question arose whether the Union of India must apply Pension Regulations (Paragraphs 9, 18) and a 1987 letter (Note 5) for calculating qualifying service, and if DSC personnel are entitled to service deficiency condonation for a second pension per Paragraphs 125 (1961) and 44 (2008) Regulations. Finally, the Supreme Court ruled that the Union of India must first determine qualifying service length, considering rounding off. If a shortfall of one year or less remains, DSC personnel are entitled to condonation for pension eligibility, consistent with earlier judgments. The Court found no inconsistency between DSC-specific provisions and general condonation rules, asserting that executive letters cannot amend or override clear regulations. The appeals were dismissed.
