Doctrine of Basic Structure: Why Parliament Cannot Amend Certain Parts of the Constitution
Date Published

The doctrine of basic structure is one of the most important judicial innovations in Indian constitutional law. It places a limit on Parliament's power to amend the Constitution, ensuring that its core identity can never be destroyed, even through a valid constitutional amendment.
This topic is essential for every judiciary aspirant, since it connects multiple landmark cases and forms the basis for understanding the relationship between Parliament, the judiciary, and the Constitution itself.

Origin of the Doctrine
The basic structure doctrine was laid down by a thirteen judge bench of the Supreme Court in Kesavananda Bharati v. State of Kerala (1973). The Court held that while Parliament has wide power to amend the Constitution under Article 368, this power does not extend to altering or destroying the basic structure or essential framework of the Constitution.
This was a middle path between two extreme positions: one that Parliament could amend any part of the Constitution, including fundamental rights, without limitation, and another that fundamental rights could never be touched at all. The basic structure doctrine allows amendments while protecting the Constitution's core identity.

What Counts as Basic Structure
The Supreme Court has never given an exhaustive, closed list of basic structure features, deciding this on a case-by-case basis. However, several elements have been repeatedly recognised, including the supremacy of the Constitution, the rule of law, separation of powers, judicial review, federalism, secularism, free and fair elections, and the harmony between fundamental rights and directive principles of state policy.
• Supremacy of the Constitution over Parliament, recognised in Kesavananda Bharati and reaffirmed in Minerva Mills.
• Judicial review as an essential feature, confirmed in Indira Nehru Gandhi v. Raj Narain and Minerva Mills.
• Free and fair elections, held to be part of the basic structure in Indira Nehru Gandhi v. Raj Narain.
• Balance between fundamental rights and directive principles, protected in Minerva Mills v. Union of India.
How the Doctrine Evolved Through Case Law
Soon after Kesavananda Bharati, the doctrine was tested in Indira Nehru Gandhi v. Raj Narain (1975), where the Supreme Court struck down a constitutional amendment for the first time using this doctrine, holding that placing the Prime Minister's election beyond judicial review destroyed the basic structure.
In Minerva Mills v. Union of India (1980), the Court struck down provisions of the 42nd Amendment that gave Parliament unlimited amending power and removed judicial review of amendments, reaffirming that a limited amending power is itself part of the basic structure.
In Waman Rao v. Union of India (1981), the Court applied the doctrine to laws placed under the Ninth Schedule, holding that laws added after 24 April 1973, the date of the Kesavananda Bharati judgment, could be tested against the basic structure.
