Basic Structure Doctrine of the Indian Constitution

The Basic Structure Doctrine is one of the most important principles of Indian constitutional law. It limits Parliament’s power to amend the Constitution of India under Article 368 by providing that Parliament may amend any provision of the Constitution, but it cannot alter, damage or destroy the Constitution’s basic structure or essential identity.

The doctrine was authoritatively laid down by a thirteen-judge Bench of the Supreme Court in His Holiness Kesavananda Bharati Sripadagalvaru v. State of Kerala, (1973) 4 SCC 225. The judgment was delivered by a narrow majority of 7:6 and fundamentally changed the law relating to constitutional amendments in India. The doctrine is closely connected with the Preamble, Fundamental Rights and the Directive Principles of State Policy.

Why the Basic Structure Doctrine Matters

The doctrine answers a fundamental constitutional question: Can Parliament use the amending power to change the Constitution without any substantive limit?

The Supreme Court’s answer in Kesavananda Bharati was no. Parliament possesses a wide constituent power under Article 368, but that power is not unlimited. The Constitution may be amended, but its core identity must survive.

The doctrine therefore performs two functions:

it preserves constitutional supremacy against unlimited amendment; and
it allows democratic constitutional change while preventing destruction of foundational constitutional principles.

Article 368: Power and Procedure to Amend the Constitution

Article 368 is contained in Part XX of the Constitution. It recognises Parliament’s constituent power to amend the Constitution by addition, variation or repeal, subject to the procedure prescribed in the Article.

A Constitution Amendment Bill may be introduced in either House of Parliament. It must be passed in each House by:

a majority of the total membership of that House; and
a majority of not less than two-thirds of the members present and voting.

For amendments affecting specified federal provisions, ratification by at least one-half of the State Legislatures is also required before the Bill is presented to the President for assent.

The current text of Article 368 therefore expressly confers constituent power upon Parliament. However, that constituent power remains subject to the implied limitation created by the Basic Structure Doctrine.

Constitutional Amendment before Kesavananda Bharati

The development of the Basic Structure Doctrine cannot be understood without examining the earlier conflict between Parliament and the Supreme Court over the amendability of Fundamental Rights.

Shankari Prasad v. Union of India

In Shankari Prasad Singh Deo v. Union of India, AIR 1951 SC 458, the Supreme Court upheld Parliament’s power to amend Fundamental Rights. The Court held that a constitutional amendment under Article 368 was not “law” within Article 13(2) and therefore could alter Fundamental Rights.

Sajjan Singh v. State of Rajasthan

In Sajjan Singh v. State of Rajasthan, AIR 1965 SC 845, the Supreme Court again upheld Parliament’s authority to amend Fundamental Rights. However, important doubts were expressed in the separate opinions of Justices Hidayatullah and Mudholkar about whether there were inherent limitations on the amending power.

I.C. Golak Nath v. State of Punjab

In I.C. Golak Nath v. State of Punjab, AIR 1967 SC 1643, an eleven-judge Bench held by majority that Parliament could not amend Fundamental Rights. The Court treated constitutional amendments as “law” for the purposes of Article 13.

The decision significantly restricted Parliament’s amending power and triggered a constitutional response.

The Twenty-Fourth Amendment, 1971

The Constitution (Twenty-fourth Amendment) Act, 1971 was enacted in response to Golak Nath. It expressly declared that Parliament may, in exercise of its constituent power, amend any provision of the Constitution in accordance with Article 368.

It also amended Article 13 to clarify that nothing in Article 13 applies to constitutional amendments made under Article 368.

This amendment set the stage for the constitutional challenge decided in Kesavananda Bharati.

Kesavananda Bharati v. State of Kerala

His Holiness Kesavananda Bharati Sripadagalvaru v. State of Kerala, (1973) 4 SCC 225, was decided by a thirteen-judge Bench, the largest Bench in the history of the Supreme Court of India.

The case arose in the context of challenges involving land reform legislation and constitutional amendments, including the Twenty-fourth, Twenty-fifth and Twenty-ninth Amendments.

The Central Question

The central constitutional question was whether Parliament’s power under Article 368 was unlimited or whether there existed implied limitations on the amending power.

The Holding

By a majority of 7:6, the Supreme Court held that:

Parliament has wide power to amend the Constitution under Article 368;
the amending power extends to all provisions of the Constitution, including Fundamental Rights;
however, Parliament cannot alter or destroy the basic structure or essential features of the Constitution.

The decision thus rejected both extremes: it rejected the proposition that Fundamental Rights were wholly unamendable, and it also rejected the proposition that Parliament’s amending power was unlimited.

What Constitutes the Basic Structure?

The Supreme Court did not formulate one exhaustive or closed list of basic features. Different judges identified different constitutional principles, and later cases developed the doctrine further.

Features that have been recognised in constitutional jurisprudence as forming part of the basic structure include:

supremacy of the Constitution;
republican and democratic form of government;
secularism;
federal character of the Constitution;
separation of powers;
rule of law;
judicial review;
independence of the judiciary;
free and fair elections;
limited amending power;
the dignity and liberty of the individual;
equality as a constitutional value;
the balance between Fundamental Rights and Directive Principles;
parliamentary democracy;
the principle of constitutionalism; and
the essential federal distribution of power.

The list is not exhaustive. Whether a particular principle forms part of the basic structure depends upon the constitutional context and the effect of the amendment under challenge.

Sikri C.J.’s Formulation

Chief Justice S.M. Sikri identified several fundamental features, including:

supremacy of the Constitution;
republican and democratic form of government;
secular character of the Constitution;
separation of powers; and
federal character of the Constitution.

He also emphasised that the dignity and freedom of the individual form part of the Constitution’s basic foundation.

Indira Nehru Gandhi v. Raj Narain

In Indira Nehru Gandhi v. Raj Narain, 1975 Supp SCC 1, the Supreme Court applied the Basic Structure Doctrine to the Constitution (Thirty-ninth Amendment) Act, 1975.

The amendment attempted to immunise the election of specified high constitutional office-holders from ordinary judicial adjudication. The Supreme Court struck down the relevant constitutional provision to the extent that it damaged basic features including:

free and fair elections;
rule of law;
judicial review; and
democratic constitutionalism.

This case was important because it demonstrated that the doctrine was not merely theoretical. Constitutional amendments could actually be invalidated for violating basic structure.

The Forty-Second Amendment and the Attempt to Remove Limits

The Constitution (Forty-second Amendment) Act, 1976 sought to strengthen Parliament’s amending power. It inserted clauses (4) and (5) into Article 368.

These provisions attempted, broadly, to:

exclude constitutional amendments from judicial review; and
declare that there would be no limitation whatever on Parliament’s constituent power.

These provisions directly challenged the principle established in Kesavananda Bharati.

Minerva Mills Ltd. v. Union of India

In Minerva Mills Ltd. v. Union of India, (1980) 3 SCC 625, the Supreme Court struck down clauses (4) and (5) of Article 368 inserted by the Forty-second Amendment.

The Court held that:

limited amending power is itself part of the basic structure;
judicial review is part of the basic structure; and
harmony and balance between Fundamental Rights and Directive Principles is an essential feature of the Constitution.

The Court rejected the proposition that Parliament could convert a limited Constitution into one in which the amending authority was legally unlimited.

Waman Rao v. Union of India

In Waman Rao v. Union of India, (1981) 2 SCC 362, the Supreme Court considered the application of the Basic Structure Doctrine to laws placed in the Ninth Schedule.

The Court treated 24 April 1973, the date of the Kesavananda Bharati judgment, as a significant constitutional cut-off date. Constitutional amendments placing laws in the Ninth Schedule after that date were open to examination under the Basic Structure Doctrine.

S.R. Bommai v. Union of India

In S.R. Bommai v. Union of India, (1994) 3 SCC 1, the Supreme Court recognised secularism and the federal character of the Constitution as basic features.

The judgment is especially important because it shows that basic structure principles may operate beyond Article 368 litigation and inform broader constitutional interpretation.

L. Chandra Kumar v. Union of India

In L. Chandra Kumar v. Union of India, (1997) 3 SCC 261, the Supreme Court held that the power of judicial review vested in the High Courts under Articles 226 and 227 and in the Supreme Court under Article 32 forms part of the basic structure.

Tribunals may perform an important adjudicatory role, but they cannot entirely exclude the constitutional judicial-review jurisdiction of the High Courts and Supreme Court.

I.R. Coelho v. State of Tamil Nadu

In I.R. Coelho v. State of Tamil Nadu, (2007) 2 SCC 1, a nine-judge Bench held that laws inserted into the Ninth Schedule after 24 April 1973 are not automatically immune from judicial review.

If a Ninth Schedule law damages or destroys Fundamental Rights that form part of the Constitution’s basic structure, the law may be invalidated.

The judgment reinforces the principle that Parliament cannot achieve indirectly through Article 31B and the Ninth Schedule what it cannot constitutionally achieve directly through Article 368.

National Judicial Appointments Commission Case

In Supreme Court Advocates-on-Record Association v. Union of India, (2016) 5 SCC 1, commonly called the NJAC case, the Supreme Court struck down the Constitution (Ninety-ninth Amendment) Act, 2014 and the National Judicial Appointments Commission Act, 2014.

The majority held that the amendment impaired the independence of the judiciary, which is part of the basic structure.

The decision remains a major modern application of the doctrine to a constitutional amendment concerning judicial appointments.

Basic Structure and Judicial Review

Judicial review is central to the doctrine. If Parliament itself were the sole judge of whether an amendment destroyed the Constitution’s basic structure, the limitation would become ineffective.

The Supreme Court therefore retains authority to examine constitutional amendments and invalidate them if they violate the basic structure.

This does not mean that courts exercise a general power to rewrite constitutional amendments. The judicial inquiry is whether the amendment, in its effect and constitutional operation, damages an essential feature of the Constitution.

Basic Structure and Parliamentary Sovereignty

India does not follow the British model of absolute parliamentary sovereignty. Parliament derives its authority from the Constitution and remains subject to constitutional limitations.

The Indian constitutional system is therefore based on constitutional supremacy, not unlimited legislative or constituent supremacy.

Parliament’s Article 368 power is exceptionally wide, but Parliament remains a constitutional organ functioning under a controlled Constitution.

Basic Structure and Fundamental Rights

The Basic Structure Doctrine does not mean that every Fundamental Right, in every detail, is completely unamendable. Parliament may amend Fundamental Rights.

The constitutional limitation arises when an amendment damages or destroys principles that form part of the Constitution’s basic structure.

For example, equality, liberty, rule of law, judicial review and dignity may have basic-structure significance, but the precise analysis depends upon the amendment and the constitutional principle affected.

Basic Structure and Directive Principles

The doctrine also protects the constitutional balance between Fundamental Rights and Directive Principles.

In Minerva Mills, the Supreme Court held that the Constitution is founded upon a harmony between Parts III and IV. Absolute destruction of one in favour of the other would damage the constitutional balance.

Thus, the doctrine does not treat Fundamental Rights and Directive Principles as permanent adversaries. Instead, it protects their constitutional equilibrium.

Can the Preamble Be Amended?

Yes. In Kesavananda Bharati, the Supreme Court held that the Preamble is part of the Constitution and may be amended under Article 368.

However, Parliament cannot use the amending power to destroy the basic features reflected in the Preamble, such as democracy, republicanism, secularism, liberty, equality or the unity and integrity of the nation.

Constitutional Amendments Requiring State Ratification

Article 368 requires ratification by at least one-half of the State Legislatures where an amendment affects specified federal provisions, including matters relating to:

the election of the President;
the extent of executive power of the Union and States;
the Supreme Court and High Courts in specified respects;
distribution of legislative powers between the Union and States;
the Seventh Schedule Lists;
representation of States in Parliament; and
Article 368 itself.

This ratification requirement reflects the federal structure of the Constitution.

Difference Between Ordinary Law and Constitutional Amendment

Feature	Ordinary Legislation	Constitutional Amendment
Source of power	Legislative provisions such as Articles 245–246	Constituent power under Article 368
Voting requirement	Usually simple majority, subject to Constitution	Special majority prescribed by Article 368
State ratification	Generally not required	Required for specified federal amendments
Can alter constitutional text?	No	Yes
Subject to judicial review?	Yes	Yes, including Basic Structure review
Can destroy basic structure?	No	No

Is There an Exhaustive List of Basic Features?

No. The Supreme Court has never declared a closed and exhaustive catalogue of basic features.

This flexibility is deliberate. Constitutional amendments may affect the Constitution in different ways, and the Court examines whether the amendment damages the Constitution’s essential architecture, identity or foundational principles.

Accordingly, students should avoid writing that there are only five, ten or any fixed number of basic features.

Criticism of the Basic Structure Doctrine

The doctrine has attracted significant academic criticism. Common criticisms include:

the expression “basic structure” does not expressly appear in Article 368;
the doctrine gives judges substantial power over constitutional change;
there is no exhaustive list of basic features;
the doctrine may involve judicial evaluation of political and institutional choices; and
the 7:6 majority in Kesavananda Bharati produced several separate opinions, making the precise ratio historically complex.

Supporters respond that the doctrine is necessary to preserve constitutionalism, prevent authoritarian constitutional amendments and protect the supremacy and continuing identity of the Constitution.

Importance of the Doctrine

The Basic Structure Doctrine is significant because it:

prevents constitutional self-destruction through amendment;
preserves constitutional supremacy;
protects judicial review and rule of law;
preserves democracy, secularism and federalism;
protects the independence of the judiciary;
ensures that Parliament’s constituent power remains limited; and
maintains the continuity of India’s constitutional identity while allowing amendment and reform.

5-Mark Answer: Basic Structure Doctrine

The Basic Structure Doctrine limits Parliament’s power to amend the Constitution under Article 368. It was laid down by a thirteen-judge Bench in Kesavananda Bharati v. State of Kerala, (1973) 4 SCC 225. The Supreme Court held that Parliament may amend any provision of the Constitution, including Fundamental Rights, but cannot damage or destroy its basic structure. Basic features recognised in later cases include constitutional supremacy, democracy, secularism, federalism, rule of law, judicial review, independence of the judiciary, free and fair elections and limited amending power. The doctrine preserves the essential identity of the Constitution while allowing constitutional change.

Conclusion

The Basic Structure Doctrine is the constitutional principle that reconciles amendment with continuity. Parliament may alter the Constitution to meet changing social, political and institutional needs, but it cannot use the amending power to destroy the Constitution’s essential identity. From Kesavananda Bharati through Minerva Mills, I.R. Coelho and the NJAC judgment, the Supreme Court has consistently maintained that the Indian Constitution is amendable but not destructible.
