Basic Structure Doctrine and Limitations on Amending Power

Basic structure doctrine is the constitutional principle that Parliament's power to amend the Constitution under Article 368, though wide, cannot be used to alter or destroy the identifying, foundational features of the Constitution itself. The doctrine did not emerge from any single article of the text; it was judicially evolved as the Supreme Court's answer to a question the framers had left open — can an elected Parliament use its amending power to rewrite the Constitution's core character? The doctrine now operates as the outer boundary on the exercise of Article 368, above and beyond the article's own procedural requirements.

Article 368 and the Amendment Procedure

Article 368 vests Parliament with constituent power to amend the Constitution "by way of addition, variation or repeal" of any provision, following the procedure set out in the article. An amendment can be initiated only by introducing a Bill in either House of Parliament. The Bill must be passed in each House by a majority of the total membership of that House and by a majority of not less than two-thirds of the members present and voting. Once passed, the Bill is presented to the President, who is required to give assent, after which the Constitution stands amended according to its terms.

A proviso to Article 368(2) adds a further safeguard for amendments touching specified federal or structural matters — such changes require ratification by not less than one-half of the State legislatures before the Bill is presented to the President for assent. This ratification requirement operates in addition to, not instead of, the special majority needed in Parliament, and its breach has itself been a ground on which amendments have later been struck down.

From Golaknath to Kesavananda Bharati

The idea that Parliament's amending power has inherent limits developed through a sequence of Supreme Court rulings before it was formally articulated. In Golaknath (1967), the Court exercised judicial review over constitutional amendments themselves, treating them as open to scrutiny rather than as automatically beyond challenge — a step that set the stage for the doctrine that followed.

The doctrine received its definitive statement in Kesavananda Bharati vs. State of Kerala, AIR 1973 SC 1461, decided by a full bench of thirteen judges. The Court held that while Parliament could amend any part of the Constitution, including the Fundamental Rights, it could not use Article 368 to alter or destroy the "basic structure" of the Constitution. Any amendment found to violate the basic structure would be treated as beyond the powers of Article 368, regardless of whether it followed the article's own procedure. Judicial review was treated as necessary to this limitation, since only continuing court scrutiny could keep the check meaningful, and features such as the sovereignty and territorial integrity of the country, the federal system, and the framework of parliamentary government were named among the elements that could not be amended away.

Basic Features Identified Over Time

The Constitution nowhere lists what its "basic structure" consists of; the content of the doctrine has instead been filled in case by case. Features that have come to be recognised in this line of cases include: supremacy of the Constitution; the sovereign, democratic and republican character of the polity; the secular character of the Constitution; separation of powers among the legislature, executive and judiciary; the federal character of the Constitution; the unity and integrity of the nation; the objective of a welfare state; judicial review; and the framework of parliamentary government. Because the list has grown through adjudication rather than through a single authoritative definition, it remains open-ended rather than closed.

Testing the Doctrine: The 42nd Amendment and Minerva Mills

Parliament's response to Kesavananda Bharati came through the 42nd Amendment Act (1976), which inserted clauses (4) and (5) into Article 368. These clauses declared that there was no limitation on Parliament's constituent power to amend any part of the Constitution, and that no amendment could be questioned in any court on any ground, including inconsistency with Fundamental Rights.

The Supreme Court struck down these clauses in Minerva Mills vs. Union of India (1980). The Court held that Parliament's amending power under Article 368 is itself a limited power, and that a body possessing a limited power cannot use that very power to convert itself into an unlimited one. Judicial review was held to be a basic feature that could not be excluded even through the constitutional amendment process. The Court also held that the balance between Fundamental Rights and the Directive Principles of State Policy is part of the basic structure, so that giving directive principles automatic precedence over fundamental rights would itself damage a basic feature.

A related episode arose out of Indira Gandhi vs. Raj Narain (1975), where a constitutional amendment inserting Article 329-A sought to place the election of the Prime Minister and the Speaker beyond the scrutiny of courts. The Supreme Court held this to be beyond the amending power on basic-structure grounds, reaffirming the doctrine in the period leading up to the 42nd Amendment.

Later Application of the Doctrine

The Supreme Court has since applied the basic structure doctrine to test amendments and amendment-linked provisions in specific contexts.

• In Kihoto Hollohon vs. Zachilhu (1993 SC 412), the Court examined Paragraph 7 of the Tenth Schedule, which sought to bar the jurisdiction of courts over disqualification decisions under the anti-defection law. It held the provision invalid because the change had not been ratified by State legislatures as required by the proviso to Article 368(2), since it affected a matter covered by that proviso.
• In the Waman Rao case (1980), the Court clarified that the basic structure doctrine, as settled in Kesavananda Bharati, applies to constitutional amendments made after 24 April 1973 — the date of that judgment.
• In I.R. Coelho vs. State of Tamil Nadu (2007), the Court examined whether laws placed in the Ninth Schedule by constitutional amendment could still be tested against the basic structure and against Fundamental Rights under Articles 14, 19 and 21, even though Ninth Schedule laws are ordinarily shielded from challenge. The Court held that laws inserted into the Ninth Schedule after 24 April 1973 remain open to challenge if their effect damages the basic structure.

FAQ

Q1. What is the basic structure doctrine? It is the principle, laid down by the Supreme Court in Kesavananda Bharati (1973), that Parliament's power to amend the Constitution under Article 368 cannot be used to alter or destroy the Constitution's basic or essential features.

Q2. Which case established the basic structure doctrine? Kesavananda Bharati vs. State of Kerala, AIR 1973 SC 1461, decided by a bench of thirteen judges, is the case that formally established the doctrine.

Q3. Can Parliament amend Fundamental Rights? Yes. The Supreme Court has held that Parliament can amend any part of the Constitution, including Fundamental Rights, under Article 368, as long as the amendment does not damage the basic structure.

Q4. What did the Minerva Mills case decide? It struck down clauses (4) and (5) inserted into Article 368 by the 42nd Amendment Act, which had sought to make Parliament's amending power unlimited and unreviewable, holding that judicial review is itself a basic feature.

Q5. Does the basic structure doctrine apply to Ninth Schedule laws? Yes. In I.R. Coelho vs. State of Tamil Nadu (2007), the Supreme Court held that laws placed in the Ninth Schedule after 24 April 1973 remain open to challenge if they violate the basic structure.
