The correct answer is (a). The In re Berubari case was a 1960 case in which the Supreme Court of India ruled that the preamble to the Constitution of India is not a part of the Constitution. The court held that the preamble is a “prologue” to the Constitution and does not have any legal force.
The other options are incorrect. In the Keshavanand Bharti case (1973), the Supreme Court ruled that the basic structure of the Constitution is not amendable. In the Maneka Gandhi case (1978), the Supreme Court ruled that the right to life and personal liberty is a fundamental right. In the S.R. Bommai case (1994), the Supreme Court ruled that the President can’t dismiss a state government without the recommendation of the Chief Justice of India.
The In re Berubari case was a landmark case in Indian constitutional law. The court’s ruling has been criticized by some scholars, who argue that the preamble is an essential part of the Constitution and should be given legal force. However, the court’s ruling has been upheld in subsequent cases, and the preamble is not considered to be a part of the Constitution.
