The Basic Structure Doctrine

No revision of Indian constitutional law is complete without understanding why some amendments that Parliament validly passed — following every procedural requirement of Article 368 to the letter — were still struck down by the courts. The answer is the Basic Structure Doctrine, and its story is really the story of a decades-long tug-of-war between Parliament's amending power and the judiciary's role as constitutional guardian.

The build-up. In Shankari Prasad (1951) and again in Sajjan Singh (1965), the Supreme Court held that Parliament's power under Article 368 to amend the Constitution extended even to Fundamental Rights, and that an amendment was not "law" within the meaning of Article 13(2) (which voids any law inconsistent with Part III) — so Fundamental Rights could, in principle, be amended away. That position reversed sharply in Golaknath v. State of Punjab (1967), where the Court held, by a narrow majority, that Parliament could not amend Part III at all — Fundamental Rights were given a "transcendental" position beyond the reach of ordinary amendment. Parliament's response was swift and direct: the 24th Amendment (1971) expressly declared that Parliament does have the power to amend any part of the Constitution, including Part III, and that such an amendment is not "law" under Article 13.

The case itself. That set up the confrontation in Kesavananda Bharati v. State of Kerala (1973), decided by the largest bench the Supreme Court has ever assembled — 13 judges — who ruled, by a wafer-thin 7–6 majority, on a case that had begun as a dispute over land reform affecting a Kerala mutt headed by Swami Kesavananda Bharati. The Court upheld the validity of the 24th Amendment (Parliament can amend any part of the Constitution, Fundamental Rights included) but simultaneously carved out a limit nowhere stated in the constitutional text itself: Parliament's amending power under Article 368 does not extend to altering the "basic structure" or "basic features" of the Constitution. What exactly counts as "basic structure" was deliberately left open-ended and has been filled in, case by case, over the following decades — supremacy of the Constitution, republican and democratic form of government, secular character, separation of powers, federalism, judicial review, free and fair elections, the rule of law, and the dignity of the individual guaranteed by Fundamental Rights have all been recognised in various later judgments as basic features, though no single authoritative closed list exists.

The doctrine in action. The doctrine was not merely theoretical — it has actually struck down amendments and amendment-clauses on several landmark occasions:

• Indira Nehru Gandhi v. Raj Narain (1975) struck down a clause of the 39th Amendment that had tried to place the Prime Minister's own election dispute beyond the reach of any court — the Court held that free and fair elections, and judicial review of electoral disputes, were part of the basic structure.
• Minerva Mills v. Union of India (1980) struck down parts of the 42nd Amendment that had tried to give Directive Principles (Article 39(b)/(c), via an expanded Article 31C) blanket primacy over Fundamental Rights, and had tried to place constitutional amendments themselves beyond judicial review — the Court held that the balance between Part III and Part IV was itself part of the basic structure, and that limited government (as opposed to unlimited amending power) was too.
• Waman Rao v. Union of India (1981) applied the doctrine specifically to the Ninth Schedule, holding that laws added to the Schedule after the Kesavananda judgment (24 April 1973) would no longer enjoy blanket immunity from Fundamental Rights review, unlike those added before that date.
• I.R. Coelho v. State of Tamil Nadu (2007), a nine-judge bench, went further still: any law placed in the Ninth Schedule, even pre-1973, could now be tested against the basic structure if it damaged the core of Articles 14, 19 or 21 — effectively ending the Ninth Schedule's status as a constitutional safe harbour.
• The Supreme Court Advocates-on-Record Association v. Union of India (2015) judgment struck down the 99th Amendment and the accompanying National Judicial Appointments Commission Act, holding that primacy of the judiciary in judicial appointments (the "collegium" system) was itself part of the basic structure's guarantee of judicial independence — perhaps the doctrine's most institutionally significant application in recent memory.

Memory hook for the Basic Structure's landmark cases — "GKM-IWS" (read as a compressed timeline): Golaknath (1967, the FR-can't-be-touched high-water mark) → Kesavananda (1973, the doctrine itself is born) → Minerva Mills (1980, DPSP-over-FR primacy struck down) → Indira Gandhi v. Raj Narain (1975, free/fair elections protected) → Waman Rao (1981, the Ninth Schedule cut-off date) → SAORA/NJAC (2015, judicial independence protected).

Practice Recall. Before reading the case-by-case list above again, try to name the five landmark cases that actually struck something down using the Basic Structure Doctrine, and what each one struck down.

Answer: Indira Nehru Gandhi v. Raj Narain (1975) — struck a 39th Amendment clause shielding the PM's election from courts. Minerva Mills (1980) — struck 42nd Amendment clauses giving DPSPs blanket primacy over FRs and ousting judicial review of amendments. Waman Rao (1981) — capped Ninth Schedule immunity at pre-24 April 1973 laws. I.R. Coelho (2007) — removed that immunity for post-1973 laws too, if they damage the core of Arts. 14/19/21. SAORA v. Union of India (2015) — struck down the 99th Amendment/NJAC.

Why it matters for exams and beyond: the doctrine is the reason India's Parliament, despite having amended the Constitution over a hundred times, has never been able to convert the document into something unrecognisable — no amendment, however procedurally valid, can abolish democracy, secularism, judicial review or federalism outright. It is simultaneously one of the most celebrated and most contested doctrines in comparative constitutional law: celebrated because it protects the Constitution's core against transient majorities, contested because it is a judge-made limit with no explicit textual anchor in Article 368 itself.
