Basic Structure of the Constitution

At the heart of Indian constitutional law lies a fundamental tension: can a sovereign Parliament, elected by the people, alter every provision of the Constitution — including Fundamental Rights? Or does the Constitution contain an inviolable core that even a constitutional amendment cannot destroy?

This question was not settled at the time of the Constitution's adoption. It took over two decades of judicial reasoning, legislative assertion, and political crisis to arrive at a settled doctrine. The story unfolds through a series of landmark cases.

1. Shankari Prasad Case (1951) — Parliament Prevails

The First Amendment Act (1951) curtailed the right to property and was immediately challenged. The Supreme Court upheld Parliament's power, reasoning that:

• Article 368 gives Parliament a plenary power to amend any part of the Constitution, including Fundamental Rights.
• The word 'law' in Article 13 (which makes laws violating Fundamental Rights void) covers only ordinary legislation, not constitutional amendment acts.
• Therefore, a constitutional amendment curtailing a Fundamental Right is valid and cannot be struck down under Article 13.

Verdict: Parliament can amend Fundamental Rights.

2. Golak Nath Case (1967) — Supreme Court Reverses Course

The Seventeenth Amendment Act (1964), which inserted certain State Acts into the Ninth Schedule (shielding them from judicial review), was challenged. The Supreme Court reversed its earlier position:

• Fundamental Rights occupy a 'transcendental and immutable' position in the Constitution.
• A constitutional amendment act is itself a 'law' within the meaning of Article 13.
• Therefore, Parliament cannot abridge or take away any Fundamental Right, even through a constitutional amendment.

Verdict: Fundamental Rights are beyond Parliament's amending reach.

3. 24th Amendment Act (1971) — Parliament Strikes Back

Reacting to Golak Nath, Parliament enacted the 24th Amendment, which:

• Explicitly amended Articles 13 and 368 to declare that Parliament has full power to abridge or take away any Fundamental Right.
• Clarified that a constitutional amendment under Article 368 is not a 'law' for the purposes of Article 13.

This was a direct legislative overrule of the Supreme Court's judgment.

4. Kesavananda Bharati Case (1973) — The Doctrine is Born

This is the most consequential constitutional judgment in Indian history. The Supreme Court:

• Upheld the 24th Amendment — confirming Parliament's power to amend Fundamental Rights.
• Overruled the Golak Nath judgment.
• But simultaneously announced the doctrine of basic structure: Parliament can amend any part of the Constitution under Article 368, but it cannot alter or destroy the basic structure of the Constitution.
• Therefore, a Fundamental Right that forms part of the basic structure remains unamendable.

This created a judicially imposed limit that is not written in the Constitution's text but is now considered its supreme interpretive principle.

Verdict: Parliament can amend Fundamental Rights but cannot damage the Constitution's basic structure.

5. Indira Nehru Gandhi Case (1975) — Doctrine Applied

The 39th Amendment Act (1975) placed election disputes involving the Prime Minister and the Speaker of Lok Sabha beyond the jurisdiction of all courts. The Supreme Court struck down this provision:

• Shielding high constitutional offices from judicial scrutiny violated the basic structure.
• Specifically, it violated free and fair elections and judicial review — both identified as basic features.

This was the first time the basic structure doctrine was actively used to strike down a constitutional amendment.

6. 42nd Amendment Act (1976) — Parliament Attempts to Override the Doctrine

Parliament, under the Emergency era, amended Article 368 to declare:

• Parliament's constituent power is unlimited.
• No constitutional amendment can be challenged in any court on any ground, including violation of Fundamental Rights.

This was an attempt to permanently immunize all amendments from judicial review.

---

7. Minerva Mills Case (1980) — Supreme Court Strikes Back Again

The Supreme Court struck down the 42nd Amendment's attempt to make Parliament's amending power absolute:

• Unlimited amending power contradicts the Constitution's very structure, which confers a limited amending power on Parliament.
• Judicial review is a basic feature — removing it destroys the Constitution's character.
• The court's famous formulation: A donee of a limited power cannot, by exercising that power, convert it into an unlimited one.
• Harmony between Fundamental Rights and Directive Principles was also identified as a basic feature.

---

8. Waman Rao Case (1981) — Retrospective Clarification

The Supreme Court reaffirmed the basic structure doctrine and gave it a temporal anchor:

• The doctrine applies only to constitutional amendments enacted after April 24, 1973 (the date of the Kesavananda Bharati judgment).
• Amendments made before that date are not open to challenge under this doctrine.

---

The Supreme Court has never provided an exhaustive or definitive list of what constitutes the basic structure. The doctrine is open-textured and evolves through case law. However, from various judgments, the following have been recognised as basic features of the Constitution:

1. Supremacy of the Constitution
2. Sovereign, democratic, and republican character of the Indian polity
3. Secular character of the Constitution
4. Separation of powers among legislature, executive, and judiciary
5. Federal character of the Constitution
6. Unity and integrity of the nation
7. Welfare state (socio-economic justice)
8. Judicial review
9. Freedom and dignity of the individual
10. Parliamentary system of government
11. Rule of law
12. Harmony and balance between Fundamental Rights and Directive Principles
13. Principle of equality
14. Free and fair elections
15. Independence of the judiciary
16. Limited amending power of Parliament
17. Effective access to justice
18. Principles underlying Fundamental Rights (the essence, not just the text)
19. Powers of the Supreme Court under Articles 32, 136, 141, and 142
20. Powers of the High Courts under Articles 226 and 227

Parliament can amend Fundamental Rights — confirmed by Kesavananda. The Golak Nath position (that FRs are completely beyond amendment) was overruled.

But Parliament cannot destroy the basic structure — even if amending a Fundamental Right, if the amendment damages a basic feature, it is unconstitutional.

The list of basic features is not closed — the Supreme Court can identify new elements through future judgments. No exhaustive enumeration exists in any constitutional text.

The doctrine has no textual basis — it is judge-made constitutional law. Article 368 itself does not mention 'basic structure.' This makes it a powerful but contested doctrine.

Temporal limit from Waman Rao — challenges under the basic structure doctrine apply only to amendments made after April 24, 1973.

The 9th Schedule and basic structure — the I.R. Coelho case (2007) held that laws inserted into the 9th Schedule after April 24, 1973 can be challenged if they violate the basic structure, effectively reducing the absolute immunity the 9th Schedule once provided.

• It places the judiciary as the ultimate guardian of constitutional identity, above Parliament's amending power.
• It ensures the Constitution cannot be transformed beyond recognition even by a majority that commands two-thirds of Parliament.
• It has been used in other democracies as a model for constitutional protection.
• It reflects the Indian Supreme Court's assertion that constitutionalism — not merely legalism — governs the republic.
• Critics argue it gives unelected judges the power to override elected representatives on foundational questions; proponents argue it is the only check against constitutional autocracy.
