Secularism: Constitutional Basis and the 42nd Amendment

Secularism constitutional basis in India rests on a cluster of Fundamental Rights that guarantee freedom of religion, later reinforced when the word "Secular" was formally written into the Preamble by the 42nd Constitutional Amendment Act, 1976. Rather than erecting a strict wall between religion and state, the Indian Constitution follows a positive model of secularism — the state gives equal respect and equal distance to every religion instead of adopting one as official or rejecting all of them. This article traces that constitutional basis, explains what the 42nd Amendment changed, and looks at how the Supreme Court has treated secularism since.

What "Secular" Means in the Indian Constitution

Secularism, as used in the Indian Constitution, is not the same as the separation-of-church-and-state idea found in some Western systems. India's version is a positive concept: the state does not uphold any single religion as a state religion, and all religions — regardless of the size of their following — receive the same status and the same degree of protection. The point is not sentiment but constitutional law: the state stays neutral among religions while still actively guaranteeing every citizen's freedom of conscience and worship.

The Pre-1976 Basis: Articles 25 to 28

Long before the word "secular" appeared in the text, the framers had already built a secular framework into the Constitution through a set of religion-related Fundamental Rights.

The Supreme Court itself observed that although the phrase "secular state" did not appear anywhere in the original text, there could be no doubt that the Constitution-makers intended to build one — a conclusion drawn precisely from the presence of Articles 25 to 28. In other words, the secular character of the Indian state existed in substance from 1950, even before it was named in the Preamble.

The 42nd Amendment Act, 1976

The 42nd Constitutional Amendment Act, 1976, amended the Preamble to add three new words: "Socialist," "Secular," and "Integrity." This remains the only occasion on which the Preamble has been amended. With this change, the Preamble's description of India moved from "SOVEREIGN DEMOCRATIC REPUBLIC" to "SOVEREIGN SOCIALIST SECULAR DEMOCRATIC REPUBLIC," making explicit what the rights-based structure of the Constitution had already implied.

The same amendment also inserted Part IVA, adding Article 51A to create a list of Fundamental Duties for citizens — originally ten duties, later expanded to eleven by the 86th Amendment Act, 2002. Among these duties are the obligations to uphold and protect the sovereignty, unity, and integrity of India, and to promote harmony and the spirit of common brotherhood among all citizens, transcending religious and other diversities — duties that sit closely alongside the constitutional commitment to secularism.

Minerva Mills v. Union of India (1980) and the Limits of the 42nd Amendment

Not every change the 42nd Amendment made survived judicial scrutiny. The same Act inserted clauses (4) and (5) into Article 368, which sought to remove all limitations on Parliament's amending power and to bar courts from reviewing constitutional amendments. It also altered Article 31C in a way that gave every Directive Principle priority over the Fundamental Rights in Articles 14, 19, and 31.

In Minerva Mills v. Union of India (1980), the Supreme Court struck down these specific insertions as unconstitutional.

The Court held that Parliament's constituent power under Article 368 cannot be stretched to let Parliament repeal or abrogate the Constitution or destroy its basic features. It reasoned that a balance between Fundamental Rights and Directive Principles is itself an essential part of the basic structure, and that judicial review — along with the limited nature of the amending power — cannot be removed even through a constitutional amendment.

Secularism as Part of the Basic Structure

Secularism, introduced into the Preamble by the 42nd Amendment, has come to be recognised as part of the Constitution's basic structure — meaning it sits among the handful of core features that Parliament cannot amend out of existence, however wide its Article 368 power otherwise runs. This gives the term "Secular" in the Preamble a legal weight well beyond a descriptive label: it operates as a standing constraint on constitutional amendment and, by extension, on ordinary legislative and executive action.
