Basic Structure Doctrine

The basic structure doctrine says that Parliament can amend any part of the Constitution, but it cannot destroy or damage its basic structure, the core features that give the Constitution its identity. Democracy, the rule of law, judicial review, federalism, secularism and free and fair elections are examples. The doctrine was created by the Supreme Court in the Kesavananda Bharati case of 1973.

It is not written anywhere in the Constitution's text. It is a limit the Court found to be implied in the idea of "amendment" itself.

Why does it exist?

Article 368 gives Parliament the power to amend the Constitution. If this power had no limit, a strong majority could, step by step, change India from a democracy into a dictatorship, abolish elections or remove the courts' power to protect rights, all through "amendments". Think of a house: you can repaint walls, add rooms or change windows, but if you pull down the foundation and pillars, it is no longer the same house. The doctrine protects the foundation and pillars.

Where did it come from?

The doctrine grew out of a long contest between Parliament and the Supreme Court, mostly over land reform laws and the right to property.

1. Shankari Prasad v. Union of India (1951): the First Amendment, which cut down the right to property, was challenged. The Court unanimously held that Parliament can amend fundamental rights too, because a constitutional amendment is not "law" under Article 13.
2. Sajjan Singh v. State of Rajasthan (1965): the Court upheld the 17th Amendment and repeated the same view.
3. A lecture in 1965: in February 1965, German jurist Professor Dietrich Conrad gave a lecture at Banaras Hindu University on "Implied Limitations of the Amending Power". He gave extreme examples to argue that some limits must exist. His idea later reached the Supreme Court through lawyers' arguments.
4. I.C. Golaknath v. State of Punjab (1967): an 11-judge bench held, by 6:5, that Parliament cannot amend fundamental rights in a way that takes them away or cuts them down, since an amendment is "law" under Article 13(2).
5. Parliament's reply: the 24th Amendment Act, 1971 declared that Parliament can amend any part of the Constitution, including fundamental rights, and that Article 13 does not apply to amendments (Articles 13(4) and 368(3)). The 25th and 29th Amendments further protected land reform laws.
6. Kesavananda Bharati v. State of Kerala (24 April 1973): a 13-judge bench, the largest ever in India, heard the case for 68 days. By 7:6, it upheld the 24th Amendment and overruled Golaknath, so Parliament can amend fundamental rights. But it added the key limit: Parliament cannot alter the basic structure. Justice H.R. Khanna's opinion was decisive in forming this majority view.

How did later cases build it up?

• Indira Nehru Gandhi v. Raj Narain (1975): the first case where the doctrine was used to strike down an amendment. The 39th Amendment had inserted Article 329A to place the election of the Prime Minister (and the Speaker) beyond court challenge. The Court struck down clause (4) of Article 329A, holding that free and fair elections and democracy are part of the basic structure.
• Minerva Mills v. Union of India (1980): the 42nd Amendment (1976) had added clauses (4) and (5) to Article 368, saying no amendment could be questioned in any court and there was no limit on Parliament's amending power. By 4:1, the Court struck these down. It held that limited amending power, judicial review and the balance between Fundamental Rights and Directive Principles are themselves basic features.
• Waman Rao v. Union of India (1981): laws put in the Ninth Schedule before 24 April 1973 (the Kesavananda date) are safe; those added after it can be tested against the basic structure.
• Kihoto Hollohan v. Zachillhu (1992): on the anti-defection law (Tenth Schedule), the Court upheld most of it but affirmed that democracy and free and fair elections are basic features, and kept the Speaker's decisions open to judicial review.
• S.R. Bommai v. Union of India (1994): secularism and federalism are part of the basic structure.
• L. Chandra Kumar v. Union of India (1997): the power of High Courts and the Supreme Court to review laws and orders (Articles 226 and 32) is a basic feature.
• I.R. Coelho v. State of Tamil Nadu (11 January 2007): a unanimous nine-judge bench confirmed that Ninth Schedule laws added after 24 April 1973 can be struck down if they damage the basic structure, including the essence of fundamental rights.
• Supreme Court Advocates-on-Record Association v. Union of India (16 October 2015), the NJAC case: by 4:1, the Court struck down the 99th Amendment and the National Judicial Appointments Commission Act, holding that they harmed the independence of the judiciary, a basic feature.
• Janhit Abhiyan v. Union of India (7 November 2022): by 3:2, the Court upheld the 103rd Amendment (10% reservation for Economically Weaker Sections), holding it did not violate the basic structure. This shows the doctrine is a test, not an automatic bar.
• Dr. Balram Singh v. Union of India (25 November 2024): a two-judge bench led by Chief Justice Sanjiv Khanna dismissed petitions against the words "socialist" and "secular", which the 42nd Amendment (1976) added to the Preamble. The Court held that Parliament's power under Article 368 covers the Preamble too. The Preamble carries the date 26 November 1949, but that date does not stop it from being amended. Adding these words did not damage the basic structure.

What features are part of the basic structure?

There is no complete official list. The Court decides case by case. Features identified so far include:

• Supremacy of the Constitution
• Sovereign, democratic and republican form of government
• Secularism
• Federalism
• Separation of powers
• Rule of law and equality
• Judicial review and independence of the judiciary
• Free and fair elections
• Limited power of Parliament to amend the Constitution
• Harmony between Fundamental Rights and Directive Principles
• Unity and integrity of the nation
• Welfare state and the essence of fundamental rights

How does it work in practice?

When a constitutional amendment is challenged, the Court asks: does this change damage or destroy an essential feature of the Constitution? If yes, that part of the amendment is void. If the change only adjusts or regulates a feature without destroying its core, it survives. The doctrine applies to constitutional amendments. A five-judge bench in Kuldip Nayar v. Union of India (2006) held that the doctrine does not apply directly to ordinary laws. Ordinary laws are tested against specific provisions, such as fundamental rights.

Commonly confused concepts

• Basic structure vs fundamental rights: Not every fundamental right, in every detail, is part of the basic structure. Parliament can amend fundamental rights (Kesavananda), as long as it does not destroy their essence or another basic feature.
• Golaknath (1967) vs Kesavananda (1973): Golaknath said Parliament cannot take away or cut down fundamental rights at all. Kesavananda said Parliament can amend any part, including fundamental rights, but cannot alter the basic structure.
• Testing amendments vs testing ordinary laws: Amendments are tested against the basic structure. Ordinary laws are tested against specific constitutional provisions like Articles 14, 19 and 21.
• Basic structure vs Preamble: The Preamble helps to identify basic features (like sovereignty, democracy and secularism), and Kesavananda held the Preamble is part of the Constitution. But the doctrine is wider than the Preamble's words. The Preamble itself can be amended, as long as the basic structure stays safe (Dr. Balram Singh, 2024).
• Indira Gandhi v. Raj Narain (1975) vs Minerva Mills (1980): The first struck down part of the 39th Amendment to protect free and fair elections. The second struck down parts of the 42nd Amendment to protect judicial review and limited amending power.

India and other countries

The idea of an "unamendable core" exists elsewhere too. Germany's Basic Law has an "eternity clause" (Article 79(3)) that bans changing certain principles. Bangladesh's Supreme Court accepted the basic structure idea in Anwar Hossain Chowdhury v. Bangladesh (1989), the Eighth Amendment case. Courts in Pakistan, Kenya and some other countries have also discussed or used similar ideas.

Issues, criticism and the way forward

• Unelected judges vs elected Parliament: Critics say the doctrine lets judges, who are not elected, overrule amendments passed by special majorities of elected representatives and often by state legislatures. They see it as judicial overreach.
• No fixed list: Because the Court adds features case by case, Parliament cannot know in advance what it may not change. Critics call this uncertain.
• The defence: Supporters say the doctrine saved Indian democracy, especially during the Emergency (1975-77), when amendments tried to shield elections and remove judicial review. They argue that some values must be safe from temporary majorities.
• Global acceptance: The doctrine has influenced courts in other countries, which supporters see as proof of its value.
• Way forward: Many experts suggest that courts use the doctrine with restraint, only for serious attacks on core features, and give clear reasons so its scope becomes more predictable.

Concepts to Know

• Constitutional amendment (Article 368): A formal change to the Constitution's text. Most need a special majority in both Houses of Parliament: a majority of the total membership of each House, and two-thirds of members present and voting. Some also need approval from half of the state legislatures.
• Judicial review: The power of courts to check whether laws and government actions follow the Constitution, and to cancel them if they do not.
• Ninth Schedule: A list in the Constitution, added by the First Amendment in 1951, for laws (mostly land reform laws) that Parliament wanted to protect from court challenge on fundamental rights grounds.
• Emergency (1975-77): The period of national emergency under Article 352 when many rights were suspended and major amendments like the 42nd were passed.
• Bench strength: The number of judges hearing a case. A larger bench's decision binds smaller benches. That is why 13-judge Kesavananda could overrule 11-judge Golaknath.
