The document discusses the Sri Sankari Prasad Singh Deo v. Union of India and State of Bihar Supreme Court case from 1952 regarding the constitutionality of the Constitution (First Amendment) Act of 1951. The Act inserted Articles 31A and 31B into the Constitution to save land reform laws from legal challenges and validate certain existing laws respectively. The case examined the three methods for amending the Constitution - ordinary majority, special majority as per Article 368, and amendments requiring additional state legislature ratification. It aimed to determine if the First Amendment was validly enacted and within Parliament's constituent powers.
