The landmark Supreme Court judgement that established the principle of the ‘basic structure’ of the Constitution of India being unamendable was the Kesavananda Bharati vs State of Kerala case in 1973.
– In this judgement, the Supreme Court held that Parliament has the power to amend any part of the Constitution, including Fundamental Rights, but cannot alter or destroy the ‘basic structure’ of the Constitution.
– This ruling overturned the previous judgement in Golaknath vs State of Punjab (1967), which had held that Fundamental Rights could not be amended.
The ‘basic structure’ doctrine does not have a single, fixed definition, but includes elements like the supremacy of the Constitution, the republican and democratic form of government, secular character, separation of powers, federal character, judicial review, etc., which the Supreme Court has identified over various cases.
