Basic Structure Doctrine — Kesavananda Bharati and After

The basic structure doctrine is the single most important judge-made limitation on the amending power of Parliament under Article 368. Born in Kesavananda Bharati v. State of Kerala, AIR 1973 SC 1461, by a wafer-thin 7:6 majority of a thirteen-judge Bench, the doctrine holds that the constituent power conferred by Article 368 is wide enough to touch every Article of the Constitution but not wide enough to abrogate those features that give the document its identity. Five decades on, every Constitution Amendment Act passed after 24 April 1973 stands liable to be tested on this touchstone — and the list of features the Supreme Court has classed as basic continues to grow case by case.

For the judiciary aspirant, the chapter has two doctrinal axes. The first is historical: the four-decision arc from Sankari Prasad to Sajjan Singh to Golak Nath to Kesavananda, ending in the doctrine's birth. The second is conceptual: a careful separation between basic structure as a brake on Article 368 (where it began) and basic structure as a brake on ordinary legislation (where, after I.R. Coelho, it has partially travelled).

The pre-Kesavananda arc — Sankari Prasad to Golak Nath

The early Supreme Court treated Article 368 as plenary. In Sankari Prasad Singh Deo v. Union of India, AIR 1951 SC 458, the Court upheld the Constitution (First Amendment) Act, 1951 — which had inserted Articles 31A and 31B and the Ninth Schedule — and held that the word "law" in Article 13(2) did not include a Constitution Amendment Act passed under the special procedure of Article 368. Fundamental rights, on that view, were as much amendable as any other provision.

Sajjan Singh v. State of Rajasthan, AIR 1965 SC 845, reaffirmed Sankari Prasad, though doubts surfaced in the concurring opinions about whether the Part III rights were really at the mercy of a two-thirds majority. Those doubts hardened in Golak Nath v. State of Punjab, AIR 1967 SC 1643, where a Special Bench of eleven judges, by 6:5, overruled Sankari Prasad and Sajjan Singh and held that fundamental rights occupy a transcendental position and cannot be abridged by an amendment under Article 368. A Constitution Amendment Act, the majority reasoned, was "law" within Article 13(2) and so void to the extent it took away Part III rights. The decision was made prospective — past amendments were saved, future ones blocked.

Parliament responded with the Constitution (Twenty-fourth Amendment) Act, 1971. Clause (4) was inserted in Article 13 declaring that nothing in Article 13 shall apply to a Constitution Amendment Act, and the marginal note of Article 368 was rewritten to make explicit the "power" — not just the procedure — of amending the Constitution. The amendment of the Constitution question now lay in wait for a larger Bench. That Bench was assembled in Kesavananda.

Kesavananda Bharati — birth of the doctrine

The petitioner was the head of a Hindu mutt in Kerala challenging State land-reform legislation; the litigation expanded into a frontal challenge to the Twenty-fourth, Twenty-fifth and Twenty-ninth Amendments. Sitting as a thirteen-judge Bench — the largest in the Court's history — the Supreme Court delivered eleven separate opinions running to over 700 pages. The headnote drawn up after the hearing recorded the majority view in two lines: Parliament has the power to amend any provision of the Constitution under Article 368, but it does not have the power to alter the basic structure or basic features of the Constitution.

The arithmetic of the majority is exam-relevant. Six judges (Sikri C.J., Shelat J., Grover J., Hegde J., Mukherjea J. and Jaganmohan Reddy J.) were prepared to invalidate amendments destroying "essential features" of the Constitution. Six judges (Ray J., Palekar J., Mathew J., Beg J., Dwivedi J. and Chandrachud J.) held the amending power to be plenary. The casting vote came from Khanna J., who held that the word "amendment" in Article 368 itself implied that the existing Constitution must survive without loss of identity, and therefore the basic structure could not be abrogated. The 7:6 majority on the basic-structure proposition was thus assembled across overlapping but not identical reasoning.

What did the Bench actually decide on the disputed amendments? The Twenty-fourth Amendment was upheld in its entirety. The first part of Article 31C, inserted by the Twenty-fifth Amendment, was upheld; its second part — which made the Legislature's declaration that a law was passed to give effect to Articles 39(b)–(c) immune from judicial review — was struck down as a delegation of effective amending power and a destruction of judicial review, itself a basic feature. The Twenty-ninth Amendment, which placed two Kerala land-reform laws in the Ninth Schedule, was upheld but made subject to challenge on basic-structure grounds.

The doctrine drew its strength from the textual word "amend". An amendment, the majority reasoned, presupposes that the thing amended survives. To rewrite the Constitution out of recognisable existence is not to amend it; it is to enact a new one. That power was reserved to a Constituent Assembly and not delegated to Parliament under Article 368.

Indira Nehru Gandhi v. Raj Narain — the doctrine applied

The first post-Kesavananda application came in Indira Nehru Gandhi v. Raj Narain, AIR 1975 SC 2299, decided during the Emergency. The Allahabad High Court had set aside the Prime Minister's election to the Lok Sabha. While the appeal was pending in the Supreme Court, Parliament passed the Constitution (Thirty-ninth Amendment) Act, 1975, inserting Article 329A which retrospectively cured the election and ousted the jurisdiction of the courts to entertain any challenge.

Clause (4) of Article 329A was struck down. Khanna J. located the violation in the rule of law and in free and fair elections; Mathew J. found a breach of equality and the rule of law; Chandrachud J. emphasised separation of powers and the absence of any norms by which the validity of the impugned election could be tested. Ray C.J., concurring on the result, kept his reasoning narrow. The collective effect was that Indira Nehru Gandhi ratified the basic-structure doctrine and added at least three features to the running list — rule of law, free and fair elections, and the principle that a court's adjudicatory function cannot be performed by Parliament under Article 368.

The 42nd Amendment and Minerva Mills

Stung by Kesavananda and Indira Nehru Gandhi, Parliament responded with the Constitution (Forty-second Amendment) Act, 1976. Clauses (4) and (5) were inserted in Article 368 to provide that no Constitution Amendment Act "shall be called in question in any court on any ground" and that there shall be "no limitation whatever on the constituent power of Parliament" to amend the Constitution. Article 31C was widened to cover laws giving effect to all the Directive Principles, not merely Articles 39(b)–(c).

In Minerva Mills v. Union of India, AIR 1980 SC 1789, a Constitution Bench of five struck down clauses (4) and (5) of Article 368. Chandrachud C.J., for the majority, held that the limited amending power was itself a basic feature; Parliament could not, by exercising that limited power, convert it into an unlimited one. Judicial review of constitutional amendments was likewise basic, since to abolish review was to leave constitutional limits without any forum to enforce them. The widened Article 31C was also struck down: by giving every Directive Principle primacy over Articles 14 and 19, the amendment destroyed the harmony between Parts III and IV that the Court treated as another basic feature.

The famous Minerva Mills sentence — that fundamental freedoms would otherwise become "a parchment in a glass case" if Parts III protections could be excluded for an uncatalogued field of laws — has been quoted in every subsequent Ninth-Schedule decision. Bhagwati J. dissented on the wide form of the order but agreed that limits on the amending power exist.

Waman Rao — the cut-off date

The companion question — when did the basic-structure doctrine begin to operate — was answered in Waman Rao v. Union of India, AIR 1981 SC 271. A Constitution Bench held that amendments to the Constitution made before 24 April 1973 (the date Kesavananda was decided) are valid and constitutional, and amendments made on or after that date are open to challenge on the ground that they damage the basic structure. The doctrine, in other words, is prospective — past inclusions in the Ninth Schedule were saved, future ones not.

Waman Rao also catalogued a few basic features — the essence of the fundamental rights, the principle of equality (which Article 31A was held to strengthen, not damage), and the rule of law. The decision is the standard reference point for the Ninth Schedule's pre-1973 immunity.

S.R. Bommai — federalism and secularism

S.R. Bommai v. Union of India, (1994) 3 SCC 1, arose out of President's Rule proclamations under Article 356. The nine-judge Bench used the basic-structure framework to characterise federalism and secularism as parts of the constitutional core. The federal nature of the Constitution, the Court said, is not a matter of administrative convenience; it is structural, and the dismissal of an elected State government has to be justified on grounds that respect that structure. Secularism — the State's equidistance from all religions — is similarly basic, with the consequence that a State government acting in defiance of secular principles can lawfully be dismissed under Article 356, subject to judicial review of the proclamation.

The doctrinal yield of Bommai for the basic-structure list is twofold: federalism and secularism are both basic features. The procedural yield — the justiciability of an Article 356 proclamation — has been treated in the chapter on emergency provisions; what matters here is that the Court treated basic-structure reasoning as available not merely to test amendments but to test executive action under Article 356.

L. Chandra Kumar — judicial review of the High Courts

In L. Chandra Kumar v. Union of India, (1997) 3 SCC 261, a seven-judge Bench struck down Article 323A(2)(d) and Article 323B(3)(d) of the Constitution — inserted by the Forty-second Amendment — to the extent they excluded the jurisdiction of the High Courts under Articles 226/227 over Administrative Tribunals. The judicial review power of the High Courts under Articles 226/227 and of the Supreme Court under Article 32, the Court held, is a basic feature; it cannot be wholly excluded even by a constitutional amendment. Tribunals were directed to function as supplemental, not substitutional, fora.

The decision is doctrinally important in three ways. First, it confirmed the addendum from S.P. Sampath Kumar v. Union of India, AIR 1987 SC 386, that judicial review can be transferred to a tribunal that is a true substitute for the High Court — but it added that the jurisdiction of the High Court under Articles 226/227 cannot be wholly ousted. Second, it widened the basic-structure category from "judicial review" simpliciter to the High Courts' supervisory writ jurisdiction in particular. Third, the case continues to govern tribunals under Articles 323A–323B and the structuring of appellate paths from them.

I.R. Coelho — basic structure and the Ninth Schedule

I.R. Coelho v. State of Tamil Nadu, (2007) 2 SCC 1, was a nine-judge Bench unanimously holding that all amendments to the Constitution made on or after 24 April 1973 by which the Ninth Schedule is amended by including new laws shall be tested on the basic-structure touchstone. After 24 April 1973, in other words, the protection of Article 31B is not absolute. A law placed in the Ninth Schedule still has to pass two tests — first, whether it violates a fundamental right that itself constitutes part of the basic structure (the Court used Articles 14, 19, 21 and 32 as the indicators); second, whether the abrogation of that right damages the essence of the basic structure when read as a whole.

Two doctrinal moves in Coelho are worth pausing over. The first is the Court's adoption of the "rights test" and the "essence test" together: a Ninth-Schedule statute that does no more than attract Article 14 incidentally is not bad; one that destroys the very essence of equality is. The second is the express acknowledgement that the basic-structure doctrine has migrated, in this limited form, from being a brake on amendments to being a brake on ordinary legislation that is shielded from fundamental rights challenge by Article 31B.

M. Nagaraj and the constitutional-identity rationale

M. Nagaraj v. Union of India, (2006) 8 SCC 212, was a five-judge Bench that upheld the Constitution (Seventy-seventh, Eighty-first, Eighty-second and Eighty-fifth) Amendments providing for reservation in promotions for SCs and STs, but it did so after subjecting them to basic-structure scrutiny. The Court grounded the doctrine in constitutional identity — "one cannot legally use the Constitution to destroy itself" — and ruled that the equality code of Article 16 is part of the basic structure, so any reservation amendment must satisfy the controlling tests of backwardness, inadequacy of representation and overall administrative efficiency. The decision is the cleanest articulation of the constitutional-identity rationale that runs through the entire post-Kesavananda jurisprudence.

NJAC — the Fourth Judges Case

The Constitution (Ninety-ninth Amendment) Act, 2014 — read with the National Judicial Appointments Commission Act, 2014 — replaced the Collegium with a six-member Commission consisting of the Chief Justice of India, the two senior-most Supreme Court judges, the Union Law Minister, and two eminent persons. In Supreme Court Advocates-on-Record Association v. Union of India, (2016) 5 SCC 1 — the Fourth Judges Case, also called the NJAC judgment — a five-judge Bench by 4:1 struck down both the amendment and the Act on basic-structure grounds, holding that the independence of the judiciary forms part of the basic structure and that the inclusion of three non-judicial members against three judicial members in the Commission compromised that independence. The presence of the Law Minister was held to introduce political influence; the undefined "eminent persons" category was held to be impermissibly vague. Chelameswar J. dissented, treating the executive role as a healthy democratic check.

The NJAC verdict is the latest application of the doctrine to a constitutional amendment that the Court found incompatible with a basic feature. It also returned the appointment process to the collegium framework laid down in the Second and Third Judges Cases — a topic developed at length in the chapter on the Union Judiciary.

Madras Bar Association — tribunal independence

A line of Madras Bar Association v. Union of India decisions — culminating in (2014) 10 SCC 1 (the National Tax Tribunal case) and (2021) 7 SCC 369 — has used the basic-structure framework to police tribunal design. The Court has held that when judicial functions are transferred from the High Courts to a tribunal, the tribunal must offer a true alternative: judicial members, secure tenure, an independent appointment process, and freedom from executive control. Tribunals built without these safeguards are liable to be struck down or read down as violating the basic feature of judicial independence and the supervisory writ jurisdiction recognised in L. Chandra Kumar.

Features the Supreme Court has classed as basic

The Supreme Court has refused to draw up an exhaustive list. The position from Kesavananda onwards is that whether a particular feature is basic falls to be decided in each case as the question arises. With that caveat, the running list of features acknowledged as basic across the post-1973 decisions is as follows:

1. Supremacy of the Constitution (Kesavananda, Bommai).
2. Sovereign, democratic and republican character of the polity (Indira Nehru Gandhi).
3. Secularism (Kesavananda, Bommai).
4. Federal character of the Constitution (Kesavananda, Bommai).
5. Separation of powers among the legislature, executive and judiciary (Kesavananda, Bommai, Indira Nehru Gandhi).
6. Unity and integrity of the nation (Kesavananda).
7. Welfare-State conception of social and economic justice; the Directive Principles in Part IV in toto (Kesavananda, Bhim Singhji v. Union of India, AIR 1981 SC 234).
8. Judicial review under Articles 32, 226 and 227 (Kesavananda, Minerva Mills, L. Chandra Kumar).
9. Rule of law (Indira Nehru Gandhi).
10. Free and fair elections (Indira Nehru Gandhi, Kuldip Nayar v. Union of India, (2006) 7 SCC 1).
11. The principles behind the fundamental rights (I.R. Coelho); the essence of the rights in Part III (Waman Rao).
12. Equality before the law and equal protection (I.R. Coelho; M. Nagaraj).
13. Freedom and dignity of the individual (Kesavananda, Bommai).
14. The objectives in the Preamble (Kesavananda).
15. Balance between fundamental rights and Directive Principles (Minerva Mills).
16. Parliamentary system of government (Kesavananda); parliamentary democracy and multi-party system (Kuldip Nayar).
17. Limited nature of the amending power conferred by Article 368 (Minerva Mills).
18. Independence of the judiciary (NJAC judgment, 2016; S.P. Gupta v. Union of India, AIR 1982 SC 149, line of authority).
19. Effective access to justice through the writ jurisdiction of the High Courts (L. Chandra Kumar).

The list is open-ended. Concepts the Court has treated as either too narrow or too institutional to qualify include the parliamentary privileges under Article 105(2) (Kihota Hollohan v. Zachillhu, AIR 1993 SC 412) and the privy purses of erstwhile Rulers (Raghunathrao Ganpatrao v. Union of India, AIR 1993 SC 1267, upholding the Constitution (Twenty-sixth Amendment) Act, 1971).

Amendments held not to violate the basic structure

Several constitutional amendments have survived the basic-structure test. The First Amendment (Articles 31A and 31B with the Ninth Schedule) was held in Waman Rao to strengthen rather than damage equality by removing inequalities in agricultural holdings. The Tenth Schedule, inserted by the Constitution (Fifty-second Amendment) Act, 1985, was upheld in Kihota Hollohan; the immunities under Article 105(2) could not be elevated into basic features so as to defeat anti-defection law. The Twenty-sixth Amendment abolishing privy purses was upheld in Raghunathrao Ganpatrao; Articles 291, 362 and 366(22) were held not to form part of the basic structure. The Twenty-fourth Amendment was upheld in Kesavananda itself. Reservation in promotions, subjected to controlling tests in M. Nagaraj, was upheld with conditions.

Two distinct domains of operation

The doctrine works in two doctrinally distinct domains, and conflating them is a common student error. The first is its original domain — a limitation on the amending power under Article 368. Here the court invalidates the Constitution Amendment Act itself, as in Indira Nehru Gandhi (Article 329A(4)), Minerva Mills (Article 368(4) and (5)), L. Chandra Kumar (Articles 323A(2)(d), 323B(3)(d)) and the NJAC verdict (Articles 124A, 124B, 124C). The second is its travelled domain — a limitation on ordinary legislation that has been shielded from fundamental-rights challenge by Article 31B (the Ninth Schedule), as worked out in I.R. Coelho. In the second domain the amendment placing the law in the Ninth Schedule is not itself struck down; the law inside the Schedule is tested.

The doctrine has not yet been used as a free-standing limitation on ordinary parliamentary legislation outside the Ninth-Schedule context. That extension was canvassed and resisted in Indira Nehru Gandhi, where the Court drew a careful distinction: ordinary law is tested on the touchstone of the fundamental rights, and constitutional amendments are tested on the touchstone of the basic structure. Mixing the two would, in the language of the Court, dilute both standards.

Constituent power vs. amending power

A recurring theme in the post-Kesavananda cases is the distinction between constituent power proper — the power to frame a Constitution that has no source above itself — and the derivative amending power conferred by Article 368, which derives from the Constitution and is bounded by it. The Court reiterated this in I.R. Coelho: the amending power has to be "within the Constitution and not outside it". By inserting the words "constituent power" in Article 368 through the Twenty-fourth Amendment, Parliament did not transmute itself into the original Constituent Assembly; it remained a Parliament under a controlled Constitution, and the basic-structure limitation continued to apply to it.

This distinction explains why Parliament cannot enlarge its own amending power through an amendment that sets up a new Constituent Assembly or that introduces a referendum mechanism circumventing Article 368 — at least so long as Kesavananda and Minerva Mills stand. A referendum that supplements Article 368 (rather than replaces it) may, on one reading of Minerva Mills, be permissible, since it would not enlarge the amending power of Parliament itself.

Why the doctrine endures

The basic-structure doctrine has been the most consequential single rule produced by the Supreme Court in the constitutional period. It has been criticised as judicial overreach — there is no textual hook in Article 368 for the limitation, and the framers, on a fair reading of the Constituent Assembly Debates, did not contemplate it. It has also been defended as the only practical safeguard against the use of a temporarily large parliamentary majority to dismantle constitutional democracy itself. The Court in Kesavananda, Minerva Mills, I.R. Coelho and the NJAC judgment has consistently chosen the second view.

For aspirants of state judicial services, CLAT PG and the SEBI Legal Officer examination, three propositions repay close attention. First, the doctrine is a basic-structure limitation on the amending power, not on legislative power generally. Second, the cut-off date is 24 April 1973 — pre-Kesavananda amendments are immune even if they would today fail the test. Third, the catalogue of basic features is open-ended and grows; recent additions include the High Courts' writ jurisdiction (L. Chandra Kumar), constitutional identity as a control on equality amendments (M. Nagaraj), and judicial independence in the design of appointments machinery (NJAC, 2016) and tribunals (the Madras Bar Association line). For the broader conceptual map of the Constitution of India notes — and especially the relationship between this chapter and the landmark constitutional cases — the basic-structure doctrine sits at the apex of the hierarchy. Readers comparing the doctrine with the express limits of Article 21 jurisprudence will see the same constitutional-identity rationale at work.

Frequently asked questions

What was the actual majority in Kesavananda Bharati and how was it counted?

The thirteen-judge Bench split 7:6 on the basic-structure proposition. Six judges (Sikri C.J., Shelat, Grover, Hegde, Mukherjea and Jaganmohan Reddy JJ.) were prepared to invalidate amendments destroying essential features; six others (Ray, Palekar, Mathew, Beg, Dwivedi and Chandrachud JJ.) held the amending power plenary. Khanna J. broke the tie by holding that the word 'amendment' in Article 368 itself implies the existing Constitution must survive without loss of identity, and the basic structure cannot be abrogated. The summary signed at the close of arguments recorded the majority view in two lines.

Does the basic structure doctrine apply only to constitutional amendments or also to ordinary legislation?

Its original domain is constitutional amendments under Article 368, where it has been used to invalidate amendments in Indira Nehru Gandhi, Minerva Mills, L. Chandra Kumar and the NJAC judgment. It has not been used as a free-standing limit on ordinary parliamentary legislation, which is tested on Part III. After I.R. Coelho (2007), however, the doctrine has been extended to test ordinary statutes that have been shielded from fundamental-rights challenge by inclusion in the Ninth Schedule — but only those laws inserted on or after 24 April 1973.

What is the cut-off date set by Waman Rao and why does it matter?

In Waman Rao v. Union of India, AIR 1981 SC 271, the Constitution Bench held that the basic-structure doctrine is prospective and operates only from 24 April 1973, the date Kesavananda was decided. Constitutional amendments made before that date — including the First, Fourth and Seventeenth Amendments inserting laws in the Ninth Schedule — are not open to challenge on basic-structure grounds. Amendments made on or after 24 April 1973 are. The same cut-off was reaffirmed in I.R. Coelho for testing Ninth-Schedule statutes.

Why did the Supreme Court strike down clauses (4) and (5) of Article 368 in Minerva Mills?

Clauses (4) and (5), inserted by the Forty-second Amendment, sought to make a Constitution Amendment Act immune from judicial review on any ground and to declare that there shall be no limitation whatever on the amending power. The Constitution Bench held in Minerva Mills v. Union of India, AIR 1980 SC 1789, that the limited nature of the amending power is itself a basic feature; Parliament cannot use that limited power to convert itself into an unlimited amending body. Judicial review of constitutional amendments is also basic. Both clauses were therefore void.

How does I.R. Coelho change the protection earlier given to Ninth-Schedule statutes?

Article 31B places statutes listed in the Ninth Schedule beyond fundamental-rights challenge. In I.R. Coelho v. State of Tamil Nadu, (2007) 2 SCC 1, a nine-judge Bench unanimously held that this immunity is not absolute for statutes inserted on or after 24 April 1973. Such statutes must satisfy two tests — first, whether they violate a fundamental right that itself forms part of the basic structure (Articles 14, 19, 21 and 32 are the indicators); second, whether the violation damages the essence of the basic structure read as a whole. Pre-1973 inclusions remain protected.

Is the independence of the judiciary part of the basic structure?

Yes. The Constitution Bench in the NJAC judgment — Supreme Court Advocates-on-Record Association v. Union of India, (2016) 5 SCC 1 — held by 4:1 that judicial independence is part of the basic structure and that the Constitution (Ninety-ninth Amendment) Act, 2014, undermined it by giving non-judicial members an effective veto in the National Judicial Appointments Commission. The amendment and the NJAC Act, 2014, were therefore struck down. The decision builds on the Second and Third Judges Cases, which had already located primacy of the judiciary in the appointments process.
