R.K. Mobisana Singh vs Kh. Temba Singh & Ors

The Supreme Court addressed the issue of seniority between promotees and direct recruits for the post of Assistant Engineer under the Public Works Department, governed by the Manipur Assistant Engineer (Civil/Mech) Recruitment Rules of 1969, 1975, and 1984, made under Article 309 of the Constitution of India. The Court held that the absence of specific rules governing inter se seniority necessitates adherence to the principles of natural justice and fair play in promotions. The judgment emphasized that ad hoc promotions without following the established procedures are invalid, thereby upholding the rights of direct recruits over promotees in seniority matters.
