Basic Structure Doctrine at 50: How One Verdict Still Shapes Indian Democracy

Five decades on, the basic structure doctrine articulated by the Supreme Court continues to be the single most consequential limit on Parliament's constitutional amending power.

The doctrine holds that while Parliament can amend virtually any part of the Constitution, it cannot alter what courts have identified as the document's foundational architecture — including judicial review itself, federalism, and free and fair elections.

Critics have long argued the doctrine hands unelected judges an outsized role in defining the Constitution's core; defenders counter that it is precisely what has prevented more dramatic swings in India's constitutional order over the decades.

The doctrine has been invoked, directly or indirectly, in nearly every major constitutional challenge since — from electoral reform cases to disputes over judicial appointments.

“The 1973 ruling that Parliament cannot amend the Constitution's 'basic structure' remains the bedrock of Indian judicial review.”
