In which landmark case did the Supreme Court hold that the Preamble is an integral part of the Constitution and can be amended under Article 368, provided the basic structure is not damaged?

💡 Solution & Explanation

In the landmark Kesavananda Bharati case of 1973, a thirteen-judge constitutional bench ruled that the Preamble is an integral part of the Constitution and amendable under Article 368 provided the basic structure remains intact. The Berubari Union opinion had previously taken the view that the Preamble was not part of the Constitution. The basic structure doctrine serves as an essential judicial check on parliamentary sovereignty in India.
