Indra Sawhney v. Union of India, also known as the Mandal Commission case, was a landmark judgment by the Supreme Court of India in 1992. The case dealt with the issue of reservation of seats in government jobs and educational institutions for socially and economically backward classes.

The case originated from a writ petition filed by Indra Sawhney and others, challenging the constitutional validity of the implementation of the recommendations of the Mandal Commission. The commission, set up in 1979, had recommended the reservation of 27% of government jobs for members of Other Backward Classes (OBCs).
