Important Constitutional Amendments of India Notes for UPSC: Article 368, 1st to 106th Amendment List, 42nd Mini-Constitution, 73rd, 74th, 101st, 103rd, 106th with Landmark Cases

The Constitution of India is a living document. It has been amended more than a hundred times since 1950, to meet new needs, to create states, to change rights and to bring in new institutions. For the UPSC Prelims, the Constitutional Amendments are among the most repeated topics: the question usually gives a subject (for example, the GST, the anti-defection law or the Panchayati Raj) and asks which amendment is linked with it, or gives a list of amendments to match. The Mains asks about the amendment procedure, the basic structure doctrine and the role of the amendments in the Indian democracy. These notes cover Article 368, the three methods of amendment, and the important amendments from the 1st to the 106th, with tables, themes and memory tricks.

Why Amendments Are So Important for UPSC

The amendments show how the Constitution has changed with the society. They connect the Polity with the Economy (GST), the Social Justice (reservations), the Federalism (Panchayati Raj and the new states) and the Judiciary (basic structure). A student who learns them theme-wise, and not in the number order, can easily recall them. Before you start, you may revise the structure of the Constitution through our notes on the Preamble and Salient Features of the Indian Constitution, the Fundamental Rights and the Parliament of India.

Article 368 and the Procedure of Amendment

A bill to amend the Constitution can be introduced in either House of Parliament, and not in the state legislature. The President must give assent, and he has no power to withhold it (since the 24th Amendment). An important limit is the basic structure doctrine, laid down in the Kesavananda Bharati case (1973), which says that Parliament cannot change the basic features of the Constitution, such as the supremacy of the Constitution, the republican and democratic form of government, secularism, federalism, the separation of powers and judicial review.

The 42nd Amendment: The Mini-Constitution

The 42nd Amendment (1976) was the biggest change since the commencement of the Constitution, and it was passed during the Emergency, on the recommendation of the Swaran Singh Committee. It changed the Preamble, added the Fundamental Duties, made the Directive Principles stronger over the Fundamental Rights, gave more powers to Parliament, curbed the judicial review and extended the term of the Lok Sabha. Many of its provisions were reversed by the 43rd and 44th Amendments (1977 and 1978) after the Emergency. The Minerva Mills case (1980) struck down the changes that took away the judicial review and gave the Fundamental Rights priority over the Directive Principles in a balanced way.

Landmark Cases on the Amendment Power

Memory Tricks

• "42 = Mini-Constitution, 44 = Property out, 52 = Defection, 61 = 18 years" is the simplest chain for the 1970s and 1980s.
• "73 and 74 are a pair": 73 for the villages, 74 for the towns.
• "101 = GST, 103 = EWS, 106 = Women" are the latest in the news.
• Remember that the Ninth Schedule was added by the 1st Amendment, and the Tenth by the 52nd.

The Mains Angle: Flexibility and Rigidity

For a Mains answer, say that the Indian Constitution is neither as rigid as the American nor as flexible as the British. The procedure of Article 368 balances the need for change with the need for stability. Argue that the amendments have helped to meet the social and economic goals, such as the land reforms, the local self-government and the GST, but a few have been criticised, such as the 42nd Amendment. The basic structure doctrine protects the core of the Constitution from the majoritarian changes, but the critics see it as a limit on the elected Parliament. End with the idea that constitutional morality and public debate are as important as the legal procedure.
