Comparative constitutional schemes

Comparative constitutional schemes — India vs USA, UK, France, Australia

Story hook

On the night of 4 November 1948, B. R. Ambedkar rose in the Constituent Assembly to introduce the Draft Constitution. A member rose to object: "Why have you borrowed so much from so many countries? Where is the originality?" Ambedkar's answer became the most famous defence of constitutional eclecticism in democratic history: "As to the accusation that the Draft Constitution has produced a good part of the provisions of the Government of India Act, 1935, I make no apologies. There is nothing to be ashamed of in borrowing. It involves no plagiarism. Nobody holds any patent rights in the fundamental ideas of a constitution."

Seventy-six years later, that magpie philosophy still defines India's constitutional uniqueness. The Preamble's "We the People" came from Philadelphia 1787. The parliamentary cabinet system came from Westminster. The Fundamental Rights came from the US Bill of Rights and the French Declaration of 1789. The Directive Principles came from the Irish Constitution of 1937. Federalism came from the British North America Act 1867 (Canada). Emergency powers came from the Weimar Republic. Judicial review came from Marbury v. Madison (USA 1803). And yet — nothing exactly like the Indian Constitution exists anywhere.

The comparative-constitutions unit is not just an academic exercise. When the Supreme Court reads down a law, it cites US, UK, South African, Canadian precedents in the same paragraph. When Parliament considers a procedural reform, it studies Westminster, Washington, Paris. The civil servant who understands why India chose one model over another holds the key to every comparative question Mains and Interview can throw.

Why this matters for UPSC

Comparative constitutional questions appear in Prelims roughly every 4-5 years (usually as a feature-match), and in Mains GS-II as a one-line scaffolding for any institutional question. Interview boards adore the "why didn't India adopt the US presidential system?" style probe. Mastering this unit also unlocks every reform debate — Should India shift to a presidential system? Should the UK have a written constitution? Should France adopt judicial review? — by giving you the structural vocabulary to compare.
