Which of the following landmark judgements of the Supreme Court of India established and subsequently reaffirmed that the Parliament's power to amend the Constitution is not unlimited and cannot alter its basic structure?

Explanation

The Supreme Court of India ruled in the Kesavananda Bharati case (1973) that the amending power of the Parliament under Article 368 is limited and does not enable it to alter the basic structure of the Constitution. This principle was subsequently reaffirmed in the Minerva Mills case (1980).
