What is the procedure and limitations for amendment of the Indian Constitution? Discuss while citing the relevant cases.

The Constitution of India can be amended only through the procedure laid down in Article 368, a provision that prescribes three distinct modes of amendment depending on the nature of the provision affected, and while Parliament's power under this Article is exceptionally wide, extending even to fundamental rights, the Supreme Court has firmly established, most notably in Kesavananda Bharati v. State of Kerala and Minerva Mills Ltd. v. Union of India, that this power is not unlimited and cannot be exercised to destroy the Constitution's basic structure.

The Procedure Under Article 368

Article 368(1) provides that Parliament may, in exercise of its constituent power, amend by way of addition, variation, or repeal any provision of the Constitution in accordance with the procedure laid down in this Article. This procedure unfolds through the following defined stages.

• Initiation: An amendment can be initiated only by the introduction of a Bill for that purpose in either House of Parliament, by either a Minister or a private member, and unlike a money bill, no prior permission of the President is required to introduce such a Bill.

• Passage in Parliament: The Bill must be passed separately in each House by a special majority, meaning a majority of the total membership of that House and a majority of not less than two-thirds of the members of that House present and voting. Unlike ordinary legislation under Article 108, there is no provision for a joint sitting of both Houses in the event of disagreement, meaning the Bill must independently secure the required majority in each House.

• Ratification by States, where applicable: Where the amendment seeks to alter any of the provisions specified in the proviso to Article 368(2), namely Articles 54, 55, 73, 162, 241, or 279A, Chapter IV of Part V, Chapter V of Part VI, Chapter I of Part XI, any List in the Seventh Schedule, the representation of States in Parliament, or Article 368 itself, the amendment must be ratified by the Legislatures of not less than one-half of the States, through resolutions passed by a simple majority of members present and voting. No fixed time limit governs this ratification, though it must be completed before the Bill is presented for presidential assent.

• Presidential Assent: Once passed by both Houses and, where necessary, ratified by the requisite number of States, the Bill is presented to the President, who is constitutionally bound under Article 368(2) to give his assent, possessing no discretion to withhold assent or return the Bill for reconsideration, a position distinct from his powers over ordinary legislation under Article 111.

• Effect: Upon presidential assent, the Constitution stands amended in accordance with the terms of the Bill.

Constitutional provisions, for the purpose of amendment, fall into three categories: provisions that can be altered through an ordinary law by simple majority, such as those governing the formation of new States or alteration of State boundaries under Articles 4 and 169, which are expressly excluded from Article 368 altogether; provisions requiring the special majority described above without any State ratification, covering the vast majority of the constitutional text; and provisions requiring both the special majority and ratification by half the States, reserved for matters touching the federal structure and Centre-State relations.

The Limitations on the Amending Power

While Article 368 itself imposes only procedural requirements, the Supreme Court, through a sequence of landmark decisions, has read into this power a substantive limitation of considerable significance, restricting not merely how an amendment may be made but what an amendment may achieve.

The question first arose in Sri Sankari Prasad Singh Deo v. Union of India, where the Supreme Court held that a constitutional amendment does not constitute "law" for purposes of Article 13(2), and treated Parliament's amending power, including its power over fundamental rights, as unrestricted, a position substantially reaffirmed in Sajjan Singh v. State of Rajasthan.

This position was reversed in I.C. Golak Nath v. State of Punjab, where the Supreme Court held by majority that a constitutional amendment does amount to "law" within the meaning of Article 13(2), and that Parliament could not use Article 368 to abridge or take away fundamental rights, applying prospective overruling to preserve amendments already made up to that point. Parliament responded through the Constitution (Twenty-Fourth Amendment) Act, 1971, inserting Article 368(3) to exclude Article 13's application to constitutional amendments, seeking to restore its unrestricted power over fundamental rights.

The definitive and enduring resolution came in Kesavananda Bharati v. State of Kerala, decided by a thirteen-judge Bench, the largest ever constituted by the Supreme Court, which by a narrow 7:6 majority upheld the Twenty-Fourth Amendment, confirming Parliament's power to amend fundamental rights, but simultaneously held that this wide power does not extend to altering or destroying the "basic structure" of the Constitution. The Court reasoned that the word "amend" in Article 368 presupposes the continued existence of the Constitution being amended, meaning something of the original document must survive any permissible amendment, and identified, without providing an exhaustive list, features such as the supremacy of the Constitution, the sovereign, democratic, and republican character of the polity, secularism, the separation of powers, judicial review, and the federal structure as illustrative components of this basic structure, leaving its precise content to be elaborated through subsequent cases.

This limitation was tested and reinforced in Indira Nehru Gandhi v. Raj Narain, where the Supreme Court struck down a clause of the Constitution (Thirty-Ninth Amendment) Act seeking to place the Prime Minister's election beyond judicial scrutiny, holding that free and fair elections form part of the basic structure's democratic character.

The doctrine received its most emphatic reinforcement in Minerva Mills Ltd. v. Union of India, where the Supreme Court struck down clauses 4 and 5 inserted into Article 368 by the Constitution (Forty-Second Amendment) Act, 1976, which had sought respectively to place all constitutional amendments beyond judicial review and to declare Parliament's amending power entirely unlimited. The Court held that judicial review forms part of the basic structure, and reasoned that Parliament's amending power, being itself a power granted and limited by the Constitution, cannot be exercised to enlarge itself into an absolute, unlimited power, since a limited amending power is itself among the Constitution's basic features, and that Parliament's power to amend is a power to amend, not a power to destroy. The Court also struck down the amended Article 31C, which had accorded blanket primacy to all Directive Principles over Articles 14 and 19, holding that this destroyed the harmony between fundamental rights and Directive Principles that itself forms part of the basic structure.

The doctrine's continued application is reflected in L. Chandra Kumar v. Union of India, where a seven-judge Bench held that judicial review under Articles 32 and 226 forms part of the basic structure and cannot be excluded even by constitutional amendment, and in I.R. Coelho v. State of Tamil Nadu, where the Supreme Court held that laws inserted into the Ninth Schedule after the date of the Kesavananda Bharati judgment remain subject to basic structure scrutiny despite the ordinarily protective effect of Article 31B.

Illustration

Suppose Parliament, following the full procedure of Article 368, including the requisite special majority in both Houses and, where necessary, ratification by half the State Legislatures, passes an amendment seeking to abolish the federal structure entirely, converting India into a wholly unitary state with no State Legislatures possessing any independent law-making authority. Applying Kesavananda Bharati v. State of Kerala, such an amendment, despite full procedural compliance, would be struck down, since the federal character of the Constitution has been recognised as forming part of its basic structure. Contrast this with an amendment altering the number of seats allocated to each State in the Rajya Sabha within reasonable and rational limits, following the proviso procedure requiring State ratification under Article 368(2); such an amendment, touching a federally significant provision but not destroying the federal structure itself, would be validly enacted, since it represents modification within the existing framework rather than an attempt to eliminate the framework altogether.

The procedure for amending the Indian Constitution, therefore, is precisely defined by Article 368 through its three-tiered scheme of special majority, State ratification where applicable, and mandatory presidential assent, but this procedural framework operates under a substantive ceiling the Supreme Court has firmly and consistently maintained since Kesavananda Bharati v. State of Kerala, reinforced through Minerva Mills Ltd. v. Union of India, L. Chandra Kumar v. Union of India, and I.R. Coelho v. State of Tamil Nadu, ensuring that Parliament's undoubtedly wide constituent power remains a tool for the Constitution's growth and adaptation, never a means of erasing the foundational identity that makes it a Constitution in the first place.
