The Constitution (93rd Amendment) Act deals with

The Constitution (Ninety-third Amendment) Act, 2005, was enacted to facilitate the extension of reservation in educational institutions [t1][t4]. This amendment inserted Clause (5) into Article 15 of the Indian Constitution, empowering the State to make special provisions for the advancement of socially and educationally backward classes (OBCs), Scheduled Castes (SCs), and Scheduled Tribes (STs) [c5][t5]. Specifically, it enabled the provision of reservations for these groups in matters of admission to educational institutions, including private institutions, whether aided or unaided by the State, while exempting minority educational institutions [t1][t8]. The amendment was a response to judicial rulings like the Inamdar case (2005) to ensure that affirmative action extended beyond government-run schools to the growing private education sector [c5][t4]. This legislative change eventually led to the Central Educational Institutions (Reservation in Admission) Act, 2006, which provided a 27% quota for OBCs [t2][t9].
