The issue of ‘creamy layer’ among the backward classes was dealt with by the Supreme Court in the Indra Sawhney vs. Union of India case (also known as the Mandal Commission case) in 1992.
In this landmark judgment, the Supreme Court upheld the constitutional validity of reservation for Other Backward Classes (OBCs) but introduced the concept of ‘creamy layer’, stating that the socially advanced members of the OBCs (the ‘creamy layer’) should be excluded from the benefits of reservation.
The judgment also capped the total reservation quota at 50% and stated that reservation in promotions was unconstitutional. The government subsequently enacted laws to implement the ‘creamy layer’ exclusion and later brought in amendments to allow reservation in promotions, which have also been subject to judicial review. The other cases listed deal with different issues: K M Nanavati vs. State of Bombay was a jury trial case; Madhu Limaye vs. Ved Murti involved legislative privileges; Sajjan Singh vs. State of Punjab dealt with the power of Parliament to amend fundamental rights (preceded Golak Nath).
