Shankari Prasad v. Union of India (1951)

Shankari Prasad Singh Deo v. Union of India, decided by the Supreme Court of India on 5 October 1951 and reported as AIR 1951 SC 458, was the first constitutional challenge to Parliament's power to amend the fundamental rights enshrined in Part III of the Constitution of India. The case arose from a direct attack on the Constitution (First Amendment) Act, 1951, which the Provisional Parliament had enacted to insert Articles 31A and 31B and the Ninth Schedule, principally to insulate zamindari abolition and agrarian reform legislation from judicial invalidation on the ground that it violated the rights to property (then Article 31) and equality (Article 14). Petitioners, drawn largely from affected zamindars in Bihar, Uttar Pradesh, and Madhya Pradesh, contended that the amendment curtailed the fundamental rights guaranteed in Part III and was therefore void. A five-judge Constitution Bench led by Chief Justice Harilal Kania heard the petitions under Article 32, the original writ jurisdiction.

The central legal question turned on the interplay between Article 13(2) and Article 368. Article 13(2) provides that the State shall not make any "law" that takes away or abridges the fundamental rights, and that any law made in contravention of that clause is, to the extent of the contravention, void. Petitioners argued that an amending Act is a species of "law" within Article 13(2), so the First Amendment, by abridging property and equality rights, was unconstitutional. The Court proceeded in stages: it first examined whether the Provisional Parliament was competent to amend the Constitution at all, then whether the amending power was procedurally exercised correctly, and finally whether the substantive content of the amendment could be tested against Part III.

The unanimous judgment, authored by Justice Patanjali Sastri, rejected the challenge on every count. The Court drew a doctrinal distinction between legislative power exercised in the ordinary course and constituent power exercised under Article 368. It held that "law" in Article 13(2) refers to ordinary legislation made in exercise of legislative powers, not to a constitutional amendment made in exercise of constituent power. Because an amendment under Article 368 is not "law" for the purposes of Article 13(2), it cannot be invalidated merely because it abridges a fundamental right. The Court also held that the Provisional Parliament had the authority to amend the Constitution under Article 379 read with Article 368, and that the First Amendment was validly enacted.

The ruling directly enabled the agrarian transformation that the Nehru government and several state ministries had prioritised. The First Amendment's Ninth Schedule mechanism—shielding listed statutes from judicial review under Article 31B—was upheld in practice, and over subsequent decades the Schedule expanded to hundreds of entries. Shankari Prasad set the template that was reaffirmed in Sajjan Singh v. State of Rajasthan (1965), where a majority of the Constitution Bench, hearing a challenge to the Constitution (Seventeenth Amendment) Act, 1964, again held that Article 368 power could reach Part III, though Justices Hidayatullah and Mudholkar registered doubts that foreshadowed later jurisprudence.

Shankari Prasad must be distinguished from the doctrine that ultimately displaced it. It is the polar opposite of the basic structure doctrine articulated in Kesavananda Bharati v. State of Kerala (1973), which held that while Parliament may amend any provision including fundamental rights, it cannot alter the essential framework or basic structure of the Constitution. The intervening landmark was Golak Nath v. State of Punjab (1967), where an eleven-judge bench by a 6–5 majority overruled Shankari Prasad and Sajjan Singh, holding that fundamental rights could not be abridged or taken away by constitutional amendment. Shankari Prasad is therefore not "good law" today on its core holding, but it remains foundational for understanding the constituent-power versus legislative-power dichotomy.

The judgment seeded the most consequential controversy in Indian constitutional history: the location of sovereignty between an amending Parliament and a reviewing judiciary. Parliament responded to Golak Nath with the Constitution (Twenty-fourth Amendment) Act, 1971, which explicitly amended Article 13 and Article 368 to declare that the amending power extends to any provision and that Article 13 shall not apply to amendments. Kesavananda upheld the Twenty-fourth Amendment but simultaneously imposed the basic-structure limitation, partially vindicating the protective instinct of Golak Nath while restoring Parliament's textual amending breadth. Subsequent decisions—Indira Nehru Gandhi v. Raj Narain (1975), Minerva Mills v. Union of India (1980), and I.R. Coelho v. State of Tamil Nadu (2007)—extended basic-structure review even to Ninth Schedule entries inserted after 24 April 1973.

For the working practitioner—the UPSC aspirant, the policy researcher, or the legislative draftsman—Shankari Prasad is the indispensable starting point of the amendability narrative that runs through Sajjan Singh, Golak Nath, Kesavananda, Minerva Mills, and Coelho. It establishes the conceptual vocabulary of constituent power and the Article 13–Article 368 relationship that every subsequent ruling either applied, overruled, or refined. Citing it correctly requires noting both its original holding and its present status: overruled by Golak Nath on the Article 13 point, then superseded by the more nuanced Kesavananda settlement under which constitutional amendments are reviewable, but only against the basic structure rather than against the full text of Part III.
