UNION OF INDIA vs DR. M.G. DIGHE .

The Supreme Court upheld the Central Administrative Tribunal's decision regarding the interpretation of Regulation 5(1) of the Indian Administrative Service (Appointment by Promotion) Regulations, 1955. The Court clarified that the 12-month period for calculating vacancies should commence from the date the Selection Committee finalized the list, which was March 16, 1989, rather than from the earlier meeting date of December 19, 1988. Consequently, the anticipated vacancies were determined to be 11, necessitating the preparation of a Select List of 22 officers, thus dismissing the Union of India's appeal.
