NIRMAL CHANDRA SINHA vs UNION OF INDIA .

The Supreme Court held that promotions in the Indian Railway Service take effect from the date they are granted, not from the date of vacancy or creation of the post, as established in previous cases such as Union of India vs. K.K. Vadera (1989) and State of Uttaranchal vs. Dinesh Kumar Sharma (2007). The Court dismissed the appeal of Nirmal Chandra Sinha for notional promotion from an earlier date, while allowing the Union of India's appeal against the High Court's directive for such promotion. The ruling emphasized adherence to the two-year tenure requirement for promotion as General Manager under applicable rules.
