All democratic countries are governed by a Constitution. In the 1967 Golaknath case, India’s Supreme Court ruled that Parliament couldn’t amend fundamental rights. Adolf Hitler’s transformation of Germany’s Weimar Constitution from democratic to dictatorial is a notable example of altering a constitution.

In 1972, the Keshavananda Bharati case settled the debate on Parliament’s power to amend the Constitution. Keshavananda Bharati, chief priest at Sri Edneer Mutt in Kerala, challenged the Kerala Land Reforms Act of 1963, claiming it violated Article 26 on religious freedom. This case allowed the Supreme Court to define Parliament’s amendment authority.

The Court’s ruling affirmed the Constitution’s supremacy and established the “basic structure doctrine,” which prevents amendments that alter the fundamental framework of the Constitution. This doctrine was later applied in the Minerva Mills and Waman Rao cases. The 24th and 25th Amendments of 1971 aimed to nullify the Golaknath judgment.

The Keshavananda Bharati case, concluded in March 1973 by a 13-judge bench, resulted in a 7:6 decision, with Justice H.R. Khanna as the tiebreaker. Although Bharati lost, the basic structure doctrine was established. Justice A.N. Ray, who dissented, later became Chief Justice of India.

The Keshavananda Bharati case was crucial in shaping Indian constitutional law, ensuring protection against potential authoritarianism.
