I.R. Coelho v. State of Tamil Nadu

This landmark judgment, also known as the Ninth Schedule Case, addressed whether laws placed in the Ninth Schedule of the Constitution are completely immune from judicial review. The Supreme Court unanimously held that laws inserted into the Ninth Schedule after April 24, 1973 (the date of the Kesavananda Bharati judgment) are subject to judicial review if they violate the basic structure of the Constitution. The Court established that Parliament cannot escape judicial scrutiny by placing laws in the Ninth Schedule. This judgment closed a significant loophole that had allowed potentially unconstitutional laws to avoid judicial review by being placed in the Ninth Schedule, thus strengthening constitutional supremacy and judicial review.
