Role of Conventions under the Constitution

Constitutional conventions role in India lies in filling the gaps that the written Constitution deliberately leaves open, supplying the unwritten rules by which the President, the Prime Minister, and the Council of Ministers actually work together where the text itself is silent. India adopted a written, exhaustive Constitution rather than Britain's convention-based one, yet the framers still leaned on established British parliamentary conventions to answer questions the text could not fully anticipate. Knowing where conventions still operate, and where India instead chose to write them into law, is a recurring theme in Indian polity.

What Is a Constitutional Convention?

A constitutional convention is an unwritten rule of political practice that guides how constitutional functionaries exercise their powers, even though no court directly enforces it. Conventions are followed because of long-standing custom and political consequence, not legal compulsion. The clearest illustration is the British Constitution, where conventions form a major source alongside statutes, common law, and legal commentaries. Well-known British conventions include the monarch acting only on Cabinet advice, appointing the majority-party leader as Prime Minister, dissolving the House of Commons on the Prime Minister's advice, and the Cabinet's collective responsibility to the House of Commons.

India's Constitution, by contrast, is an "enacted" and written document, closer in form to the American model than the British one. Yet because India adopted the British parliamentary system of government at the Union and in the states, several principles that Britain leaves to convention still had to be addressed by India's framers.

Conventions in the Making of the Indian Constitution

During the Constituent Assembly Debates, members explained that certain aspects of the President's relationship with the Council of Ministers, such as when a Ministry should resign after an adverse vote, whether a defeat on a particular measure amounts to a mere "snap vote," or when a Ministry may advise dissolution of the House of the People rather than resign, could not realistically be reduced to a rigid rule in the constitutional text. The Assembly's reasoning was that such situations should be governed by the same conventions that had grown around the powers of the British Crown in its relations with the Cabinet, since those conventions were considered well established and unlikely to be misused.

This is why the Constitution does not attempt to spell out every contingency of Cabinet government. Commentators have noted that the machinery of government adopted by India is essentially British, and that much of the British body of constitutional conventions was effectively carried over into the Indian system as convention rather than as codified law.

Where India Chose to Codify Instead of Relying on Convention

Even so, India's Constitution is markedly more exhaustive than Britain's. Several matters that other parliamentary democracies leave to ordinary legislation or to convention were instead written directly into India's constitutional text. The clearest example is the doctrine of ministerial responsibility itself: in England this rests purely on convention, but in India it is expressly stated in Article 75(3), which provides that "the Council of Ministers shall be collectively responsible to the House of the People."

The President's obligation to act on ministerial advice followed a similar path. The Supreme Court, in Ram Jawaya Kapur v State of Punjab (1955) and later in Shamsher Singh v State of Punjab (1974), held that India's parliamentary executive functions on the British pattern, with the President obliged to act on the aid and advice of the Council of Ministers. The Constitution (Forty-second Amendment) Act, 1976, converted this judicially recognised position into express text by amending Article 74(1), which now requires that the President "act in accordance with such advice." The Constitution (Forty-fourth Amendment) Act, 1978, added a proviso letting the President send the advice back once for reconsideration. What began as a convention modelled on British practice thus became binding constitutional law in India.

The comparison with Ireland is instructive: the Irish Constitution allows its President a measure of discretion, for instance to refuse a dissolution to a defeated Prime Minister, departing from British convention on that point. India's Constitution grants no comparable discretion — Article 74 leaves no room for the President to act independently of ministerial advice.

Conventions That Still Operate Without Being Written Down

Not every gap has been closed by amendment, and courts have had to determine, case by case, whether a claimed practice has actually ripened into a binding convention. In K. Lakshminarayanan v Union of India (2020), the Supreme Court held that there was no established constitutional convention requiring that nominations to the Puducherry Legislative Assembly originate from, or be made only with the concurrence of, the Chief Minister. The case shows that a convention must be shown to be a settled, recognised practice; a court will not treat an occasional or contested practice as one merely because it was followed a few times.

Constitutional Conventions vs Codified Rules

Why the Space Left for Convention Is Comparatively Narrow in India

Commentators have noted that India's Constitution deliberately included many matters that other democracies leave to ordinary legislation or to convention, in order to reduce the uncertainty that comes with unwritten practice. This makes India's Constitution one of the most detailed in the world, even though it retains a parliamentary form of government whose working logic originated in Britain's convention-based system. Conventions therefore continue to operate in India, but chiefly as a supplementary source that fills residual gaps the text has not addressed, rather than as the primary source of constitutional rules, which is the position conventions occupy in Britain.

UPSC Relevance

Prelims

• Conventions are a recognised, though unenforceable, source of the British Constitution alongside statutes, common law, and Great Charters.
• Article 75(3) codifies collective responsibility; Article 74(1), as amended by the 42nd and 44th Amendments, binds the President to ministerial advice.
• Ram Jawaya Kapur and Shamsher Singh are the leading cases on the President's constitutional position as head of a parliamentary executive.

Mains

• Discuss how the Constituent Assembly balanced codification against reliance on constitutional conventions while designing the Union executive. (GS II)
• "India's Constitution converts many British conventions into binding text." Examine with reference to the 42nd and 44th Amendments. (GS II)
• Examine the judicial approach to determining whether a political practice qualifies as a binding constitutional convention. (GS II)

FAQ

Q1. What is a constitutional convention? It is an unwritten rule of political practice that guides constitutional functionaries, followed because of custom and political consequence rather than legal enforcement.

Q2. Are constitutional conventions legally enforceable in India? Courts do not enforce a convention as such; however, where a convention has been converted into constitutional text, such as Article 75(3) or Article 74(1), it becomes legally binding.

Q3. Why does India rely less on conventions than Britain does? Because India's framers wrote an unusually detailed, enacted Constitution, deliberately including many matters, such as collective responsibility and presidential advice, that Britain leaves to convention.

Q4. Did any amendment convert a convention into law? Yes. The 42nd Amendment Act, 1976, amended Article 74(1) to bind the President to ministerial advice, a position earlier recognised only by convention and by the Supreme Court in Shamsher Singh.

Q5. Can a court decide whether something is a genuine constitutional convention? Yes. In K. Lakshminarayanan v Union of India (2020), the Supreme Court held that no established convention existed regarding Puducherry MLA nominations.
