Reservation in promotion pertains to reservations granted to Scheduled Castes and Scheduled Tribes (SCs/STs) for promotions in public employment. It has been a bitterly contested issue between the Supreme Court and Parliament. In 1992 the Court, in its Indra Sawhney judgment, found that Article 16(4) does not allow for reservation in promotion. Then, between 1995 and 2000, Parliament enacted a series of Constitutional Amendments that legalized reservation in promotion. In 2006, the Court responded with its Nagaraj judgement, which placed strict conditions on when the State could grant a SC/ST reservation in promotion. Currently, the Court is hearing a petition filed by the State of Tripura, challenging Nagaraj.
