NUTAN ARVIND vs U O I

The Supreme Court held that promotions prior to the amended rules must adhere to the old rules, emphasizing that vacancies occurring before May 1988 are governed by the previous criteria established in the Government's Memorandum dated 17th May 1957. The Court clarified that grading for promotions should be based on merit rather than solely on seniority, and that the selection list must be prepared according to merit classifications without disturbing seniority within categories. The Court upheld the principle that promotions should follow the order of names as arranged in the selection list, ensuring a fair evaluation of candidates based on their service records.
