Kesavananda Bharati v. State of Kerala: the basic structure doctrine and the limits of Parliament's amending power

The judgment of 24 April 1973 in Kesavananda Bharati Sripadagalvaru v. State of Kerala is the constitutional centre of gravity of the modern Indian republic. A thirteen-judge Constitution Bench — the largest ever assembled in Indian constitutional adjudication, convened expressly because the question to be decided required reconsideration of I.C. Golak Nath v. State of Punjab (1967) — was asked whether there were any limits at all on Parliament's power to amend the Constitution. The Court, by a 7:6 majority, held that there were: the amending power under Article 368 is plenary in its reach but is constrained by the implicit limitation that the basic structure or essential features of the Constitution cannot be abrogated.

The petition itself was, in its substantive shape, a property matter. The petitioner — Swami Kesavananda Bharati Sripadagalvaru, the head of the Edneer Mutt in Kerala — had challenged Kerala's land-reform legislation, which constrained the Mutt's ability to manage its religious endowments. The constitutional question that travelled with the petition, however, was whether the Twenty-fourth, Twenty-fifth and Twenty-ninth Constitution Amendments — passed in 1971 in the wake of Golak Nath — were within Parliament's amending competence. The answer the Court returned to that question is the part that has governed everything that has come since.

The doctrinal background

To understand what Kesavananda did, the position before it must be set out.

Sankari Prasad Singh Deo v. Union of India (1951) had held that the amending power under Article 368 was unconstrained by Part III. Sajjan Singh v. State of Rajasthan (1965) had reaffirmed that position. Golak Nath (1967), however, had reversed course: an eleven-judge Bench held by 6:5 that Fundamental Rights were beyond the amending power's reach.

Parliament responded to Golak Nath with three constitutional amendments. The Twenty-fourth Amendment (1971) reasserted Parliament's power to amend any provision of the Constitution including the Fundamental Rights, and required the President to assent to constitutional amendment bills. The Twenty-fifth Amendment (1971) curtailed the Article 31 property-rights protections and inserted Article 31C, immunising laws giving effect to certain Directive Principles from challenge on Article 14, 19 or 31 grounds. The Twenty-ninth Amendment (1972) inserted Kerala's land-reform laws into the Ninth Schedule, conferring on them the protection of Article 31B.

It was the constitutional validity of these three amendments — the Twenty-fourth, Twenty-fifth and Twenty-ninth — that Kesavananda was set down to decide. The Court was asked, in substance, whether Golak Nath should be reconsidered, and whether Parliament could, by amendment, alter Fundamental Rights.

The bench and the opinions

The bench was the largest the Supreme Court had ever convened: thirteen judges. Sikri, C.J. presided. The judges, in seniority order, were Shelat, Hegde, Grover, Jaganmohan Reddy, Palekar, Khanna, Ray, Mathew, Beg, Dwivedi, Chandrachud and Mukherjea, JJ.

The judgments ran to nearly seven hundred pages across multiple opinions. The case was argued over sixty-eight days. Eleven separate judgments were ultimately written.

The line-up of opinions reduces, for working purposes, to three positions.

The seven-judge majority. Sikri, C.J., with Shelat, Hegde, Grover, Jaganmohan Reddy, Mukherjea and Khanna, JJ., held that Parliament's amending power under Article 368 — including after the Twenty-fourth Amendment — is wide enough to amend any provision of the Constitution, but does not extend to altering its basic structure or essential features. Golak Nath was overruled in so far as it had held that Fundamental Rights were beyond the amending power; but the unlimited amending power that Sankari Prasad and Sajjan Singh had recognised was, in turn, displaced by the basic structure limitation.

The six-judge minority. Ray, Mathew, Beg, Dwivedi, Palekar and Chandrachud, JJ. would have upheld a plenary, unconstrained amending power. Golak Nath would, on their view, be overruled in full, with no implied limitation of any kind on Article 368.

Khanna, J.'s decisive opinion. Khanna, J. — alone among the thirteen — supplied the operative majority on basic structure while diverging from the seven majority on certain ancillary questions. His position, as it has come to be read, is that the basic structure limitation exists; that Golak Nath was wrong in confining the amending power's reach by reference to the categorical position of Fundamental Rights; but that the amending power cannot reduce the Constitution to one that has lost its essential character. The 7:6 majority rests, doctrinally, on Khanna, J.'s positioning.

The result on the specific amendments under challenge: the Twenty-fourth was upheld in its entirety; the first part of the Twenty-fifth (which had curtailed Article 31) was upheld; the second part of the Twenty-fifth (which had inserted the second proviso to Article 31C, ousting judicial review for laws giving effect to certain Directive Principles) was struck down by the majority that held judicial review part of the basic structure; the Twenty-ninth was upheld.

What is the basic structure?

The Court did not — and could not, given the case-by-case nature of the doctrine — supply an exhaustive list of what constitutes the basic structure. The opinions identify, illustratively, the supremacy of the Constitution; the republican and democratic form of government; the secular character of the Constitution; the separation of powers between legislature, executive and judiciary; and the federal character of the Constitution.

Subsequent cases have added to and refined the list. Judicial review under Articles 32, 136, 226 and 227 has been treated as basic structure. Free and fair elections have been added. Rule of law has been added. The unity and integrity of the nation has been added. Constitutional supremacy and individual liberty recur across the line of authority.

What the basic structure does not include, in the sense in which the doctrine operates, is the specific textual provisions in which these architectural features are expressed. Parliament can amend the provisions; what it cannot do is amend them so as to destroy the architectural feature itself.

The path the doctrine has travelled

The basic structure doctrine has been applied in a line of constitutional decisions whose collective effect has been to entrench the doctrine as the central organising principle of constitutional adjudication.

Indira Nehru Gandhi v. Raj Narain (1975) — the first substantive application of the doctrine — struck down the Thirty-ninth Amendment's attempt to immunise the election of the Prime Minister from judicial scrutiny. The amendment was held to destroy the basic structure by removing judicial review of elections.

Minerva Mills v. Union of India (1980) struck down portions of the Forty-second Amendment that had purported to make Parliament's amending power unrestricted and had given primacy to Directive Principles over Fundamental Rights. The judgment located the harmony between Fundamental Rights and Directive Principles within the basic structure.

Waman Rao v. Union of India (1981) clarified that pre-Kesavananda amendments inserting laws into the Ninth Schedule were immune from basic-structure challenge, but post-Kesavananda amendments were subject to scrutiny.

S.R. Bommai v. Union of India (1994) treated secularism as basic structure and applied the doctrine to the President's power under Article 356.

I.R. Coelho v. State of Tamil Nadu (2007) — a nine-judge Constitution Bench — held that laws inserted into the Ninth Schedule after Kesavananda are open to substantive judicial scrutiny if they violate the basic structure or Fundamental Rights. The judgment fused the basic structure doctrine with the Ninth Schedule architecture.

K.S. Puttaswamy v. Union of India (2017) — the nine-judge privacy bench — drew on the basic-structure tradition in locating the right to privacy as a fundamental right that is part of the Constitution's essential character.

What the doctrine does, in practice

The doctrine operates as a substantive constraint on the amending power. Every constitutional amendment since 1973 has been understood by Parliament, by the executive, and by the courts as subject to the basic-structure scrutiny. The political-branch awareness of the doctrine has, in the political-science literature, been credited with restraining amendments that might otherwise have been attempted.

The doctrine also operates as a substantive frame for judicial review of legislation in general. Where a statute is alleged to violate not a specific Fundamental Right but the architectural features of the Constitution — separation of powers, rule of law, secularism — the basic-structure frame supplies the conceptual scaffolding for the challenge.

The doctrine has, finally, been a significant export. Constitutional courts in Bangladesh, Pakistan, Malaysia, Kenya, Uganda, and elsewhere have adopted some version of the basic-structure doctrine, citing Kesavananda as the principal source. The Indian Supreme Court's contribution to global constitutional thought is, on most readings, the most influential single doctrinal innovation produced by any post-colonial constitutional court.

What the judgment did not decide

Three limits should be flagged.

First, the Court did not produce an exhaustive list of basic-structure features. The doctrine has been built up case by case, and the boundaries remain, in some respects, subjects of continuing constitutional argument.

Second, the doctrine constrains the amending power but does not, by itself, supply a substantive standard for what counts as ordinary legislation. Statutes are still examined against the Fundamental Rights and the constitutional architecture, but the basic-structure doctrine's primary domain is the amendment-power inquiry.

Third, the doctrine's application to amendments inserted into the Ninth Schedule was clarified — and substantially constrained — only in I.R. Coelho in 2007. The intervening period saw substantial litigation on what immunity the Ninth Schedule supplied.

The political-historical setting

The judgment cannot be read outside its political-historical setting. The Court delivered Kesavananda during the period of Indira Gandhi's first government, six weeks before her election to the Lok Sabha was challenged in Raj Narain, and two years before the imposition of the Emergency. The Government, displeased with the judgment, superseded Shelat, Hegde and Grover, JJ. — three of the majority judges — in the appointment of the next Chief Justice, appointing A.N. Ray, J. — a minority judge — instead. The supersession was a constitutional moment in its own right and is part of the institutional history of the doctrine.

The Emergency that followed — and the constitutional amendments of that period, in particular the Forty-second Amendment's attempt to neutralise the basic-structure doctrine — supplied the substantive context for Indira Gandhi v. Raj Narain and Minerva Mills. The doctrine, in surviving the Emergency-era assault, demonstrated the institutional weight it carried.

What practitioners take from the judgment today

For constitutional litigators, Kesavananda is the foundational text. Every challenge to a constitutional amendment, every argument that a statute or executive action violates the constitutional architecture, every brief on the limits of legislative or executive competence engages — at some level — with the basic-structure doctrine and the line of authority it has produced.

For the broader profession, the judgment is the principal interpretive frame for understanding what the Constitution is taken to be. The Constitution is not, on the Kesavananda reading, a text that can be reduced by amendment to a different constitution. It has an architectural identity that the amending power cannot destroy.
