First Amendment, 1951

The Constitution (First Amendment) Act, 1951 was enacted by the Provisional Parliament under the leadership of Prime Minister Jawaharlal Nehru and became the earliest substantive alteration of the freshly adopted Constitution. It was a direct legislative response to a cluster of early judicial pronouncements — notably Romesh Thappar v. State of Madras (1950) and Brij Bhushan v. State of Delhi (1950) on free speech, and the Patna High Court's decision in Kameshwar Singh v. State of Bihar (1951) which struck down the Bihar zamindari abolition law — that had constrained the government's social and economic agenda. Steered through a Select Committee, the amendment sought to immunise agrarian reform from constitutional challenge and to plug perceived gaps in the regulation of speech.

Its operative features were threefold. First, it amended Article 19(2) by adding the grounds of "public order," "friendly relations with foreign States," and "incitement to an offence" as permissible restrictions on free speech, and inserted the word "reasonable" before "restrictions" — a safeguard later invoked in judicial scrutiny. Second, it amended Article 15 by adding clause (4), empowering the State to make special provisions for the advancement of socially and educationally backward classes, Scheduled Castes and Scheduled Tribes — a response to State of Madras v. Champakam Dorairajan (1951), and the textual fountainhead of reservation jurisprudence. Third, and most consequentially, it inserted Articles 31A and 31B along with the Ninth Schedule: Article 31A protected laws providing for acquisition of estates from challenge under Articles 14 and 19, while Article 31B placed enumerated laws in the Ninth Schedule beyond the reach of Part III fundamental rights. The original Ninth Schedule contained thirteen entries, all relating to zamindari abolition.

The amendment's validity was itself contested in Shankari Prasad v. Union of India (1951), where the Supreme Court held that the word "law" in Article 13(2) did not include a constitutional amendment under Article 368, so amendments could abridge fundamental rights — a position later overruled in spirit by Golak Nath (1967) and reshaped by the basic structure doctrine in Kesavananda Bharati (1973). The Ninth Schedule's immunity was finally qualified in I.R. Coelho v. State of Tamil Nadu (2007), which held that laws inserted after 24 April 1973 are open to basic-structure review. As of 2026 the Ninth Schedule contains 284 entries, far exceeding its original land-reform purpose.

For the UPSC examination, the First Amendment is a high-frequency topic in General Studies Paper II (Indian Polity and Constitution) and recurs in Prelims. Aspirants must memorise the specific Articles it introduced (31A, 31B, Ninth Schedule) and amended (15, 19, 31), and connect it to the chain of cases from Champakam Dorairajan and Romesh Thappar through Shankari Prasad to Kesavananda Bharati and Coelho. Typical question angles ask which Articles were inserted versus amended, why the amendment was enacted, and how the Ninth Schedule's immunity has been judicially limited over time.
