This judgment by the Supreme Court of India addresses an appeal filed by an Airman (Corporal) challenging the concurrent decisions of the Armed Forces Tribunal (AFT) and the Delhi High Court, which had dismissed his plea against the refusal of a No Objection Certificate (NOC) and discharge from the Indian Air Force (IAF). The appellant had applied for and secured selection as an Assistant Professor through the Rajasthan Public Service Commission without obtaining prior permission as mandated by Air Force Order (AFO) No. 33/2017. The Supreme Court dismissed the appeal, holding that the procedural requirements outlined in the AFO are mandatory because they directly relate to operational preparedness and manning levels in the armed forces. The Court reaffirmed that members of a disciplined force do not possess an unqualified right to depart from service at will, and failure to secure prior permission validly results in the denial of an NOC.
- Factual Matrix: The appellant, serving as a Corporal in the IAF with more than seven years of service, applied for an Assistant Professor post via an RPSC advertisement in November 2020. After being selected on October 1, 2022, he sought an NOC and discharge, which the Air Officer Commanding declined on October 14, 2022, due to his failure to obtain prior permission.
- Lower Tribunal and High Court Findings: The AFT dismissed the appellant’s Original Application, finding no material evidence showing he had submitted either an online or offline prior application as required by AFO No. 33/2017. The Delhi High Court affirmed these factual findings and dismissed the subsequent writ petition.
- Object of AFO No. 33/2017: The Supreme Court noted that AFO No. 33/2017 was framed by the Chief of the Air Staff to balance the personal career aspirations of air warriors with the critical organizational objective of maintaining operational preparedness and adequate manning levels within specific trades.
- Mandatory Nature of Prior Permission: The Court rejected the argument that the procedural requirements of the AFO are merely directory and can be waived. Because Clause 19 of the AFO explicitly prescribes the rejection of an NOC request if prior permission is skipped, the requirement is mandatory. An airman cannot bypass the initial stage and present the authorities with a fait accompli upon selection.
- Absence of Proof: The concurrent factual findings of the AFT and High Court—confirming that the appellant failed to produce any documentary evidence or acknowledgments proving he attempted to submit prior applications on November 25 or 27, 2020—warranted no interference.
- No Unqualified Right to Leave Service: Citing precedent (Amit Kumar Roy v. Union of India), the Court underscored that members of a disciplined fighting force do not possess an unqualified right under Article 19(1)(g) of the Constitution to abandon service at will during their term of engagement.
- Final Outcome: The civil appeal was dismissed, leaving the parties to bear their own costs.
