HIGH COURT OF DELHI (Division Bench: V. KAMESWAR RAO and MANMEET PRITAM SINGH ARORA, JJ.; oral judgment by MANMEET PRITAM SINGH ARORA, J.) — W.P.(C) 2459/2026 with CM APPL. 11969/2026 — decided 20.02.2026. Writ petition under Article 226 by Union of India & Ors. challenging the order dated 30.05.2024 of the Armed Forces Tribunal, Principal Bench, in O.A. No. 1701/2023, whereby Hav. Jawan Singh (Retd.) (No. 01586159L) — discharged 31.12.2019 after 26 years 4 days of qualifying service — was granted the disability element of pension for Primary Hypertension (RMB 12.09.2019: 30% for life, rounded off to 50% for life) despite the RMB opining the disability NANA (onset October 2018 at Delhi, a peace station; claim earlier rejected on 08.01.2020). Petitioners contended the Tribunal erred in relying on Dharamvir Singh (2013) 7 SCC 361, a decision under the repealed Entitlement Rules, 1982, since the 2008 Entitlement Rules govern and permit no blanket presumption. Held: (i) given discharge on 31.12.2019, the plea is governed by the Entitlement Rules, 2008; (ii) even under the 2008 Rules, the onus to prove disentitlement/a causal connection other than military service remains heavy on the military establishment, not the officer; (iii) the Medical Board must record cogent reasons and causative factors, failing which the presumption is that the disease arose from the stress and strain of military service; (iv) the bald RMB entries 'onset in peace station' and 'no aggravating factors related to service were noted' are insufficient for NANA — peace-station onset having been specifically rejected in Union of India v. Col. Balbir Singh (Retd.) (2025: DHC: 5082-DB) as immaterial per Regulation 423(a), Regulations for the Medical Services of the Armed Forces, 2010, and unreasoned medical opinion condemned per Rajumon T.M. (2025 SCC OnLine SC 1064) and Bijender Singh (2025 SCC OnLine SC 895); (v) with the RMB identifying no other causal connection (and recording non-attributability to negligence or misconduct), rejection of the plea was wrongful and the Tribunal's grant, made following Dharamvir Singh and Ram Avtar (2014 SCC OnLine SC 1761) and consonant with the coordinate-Bench rulings in Gawas Anil Madso (2025: DHC: 2021-DB) and Krishna Kumar Dwivedi (W.P.(C) 88/2026), involved no error. Petition dismissed; pending applications disposed of; no costs.
