Minerva Mills Ltd. v. Union of India (1980) is the landmark case that applied the Basic Structure doctrine established in Kesavananda Bharati (1973) to strike down provisions of the Constitution (Forty-Second Amendment) Act, 1976 — the most sweeping constitutional amendment enacted during the Emergency. The 5-judge Constitution Bench held that judicial review is part of the basic structure, that Parliament cannot grant itself unlimited amending power, and that the harmony between fundamental rights and directive principles is an essential feature of the Constitution. This was the first time the Basic Structure doctrine was used to invalidate specific clauses of a constitutional amendment, proving that Kesavananda Bharati was not merely theoretical.

Facts of the case
Minerva Mills Ltd. was a textile company in Karnataka. The Central Government, under the Industries (Development and Regulation) Act, 1951, appointed a committee to investigate the company's affairs and subsequently nationalized it under the Sick Textile Undertakings (Nationalisation) Act, 1974. The company challenged the nationalization as violating its fundamental rights under Articles 14 and 19. The government relied on Articles 31C and 39(b) and (c) (directive principles regarding distribution of material resources) as amended by the 42nd Amendment. The constitutional challenge focused on two specific sections of the 42nd Amendment: Section 4 (which expanded Article 31C to protect any law implementing any directive principle — not just Articles 39(b) and (c) — from challenge under Articles 14 and 19) and Section 55 (which amended Article 368 to declare that there shall be no limitation on Parliament's constituent power and no constitutional amendment can be questioned in any court on any ground).
Issues before the court
- Whether Section 4 of the Constitution (Forty-Second Amendment) Act, 1976, which expanded Article 31C to cover all directive principles, is constitutionally valid?
- Whether Section 55 of the 42nd Amendment, which added clauses (4) and (5) to Article 368 declaring that no amendment can be questioned in any court and that there is no limitation on Parliament's constituent power, is constitutionally valid?
- Whether the removal of judicial review and the conferral of unlimited amending power on Parliament violate the basic structure of the Constitution?
What the court held
Section 55 of the 42nd Amendment struck down — Parliament cannot claim unlimited amending power — The Court held that clauses (4) and (5) inserted into Article 368 by Section 55 of the 42nd Amendment violated the basic structure doctrine. Clause (4) stated that no amendment shall be called in question in any court on any ground. Clause (5) declared that there shall be no limitation on Parliament's constituent power. The Court held that this effectively destroyed the basic structure limitation established in Kesavananda Bharati. A limited amending power is itself part of the basic structure — Parliament cannot use the amending power to make its amending power unlimited.
Section 4 of the 42nd Amendment struck down — Article 31C cannot be extended to all directive principles — The Court struck down the expanded Article 31C, which had given blanket protection to laws implementing any directive principle from challenge under Articles 14 and 19. Chief Justice Chandrachud held that this expansion destroyed the essential balance between fundamental rights (Part III) and directive principles (Part IV). The original Article 31C, as upheld in Kesavananda Bharati (protecting only laws implementing Articles 39(b) and (c)), was restored.
Judicial review is part of the basic structure — The Court explicitly held that judicial review — the power of courts to examine the constitutional validity of legislation and amendments — is an integral part of the basic structure and cannot be taken away by any constitutional amendment.
"If the power of amendment is unlimited, the entire Constitution, including the chapter on Fundamental Rights, can be repealed and a new Constitution substituted in its place. If Parliament had the power to remove all limitations on its amending power, it could convert a democratic State into a totalitarian one." — Chief Justice Y.V. Chandrachud
"The Constitution is founded on the bedrock of the balance between Parts III and IV. To give absolute primacy to one over the other is to disturb the harmony of the Constitution." — Chief Justice Y.V. Chandrachud
Justice Bhagwati dissented on Section 4 (the Article 31C expansion), arguing that giving primacy to directive principles was a legitimate constitutional choice and did not violate basic structure. However, the 4:1 majority struck it down.
Key legal principles
Judicial review as basic structure
Minerva Mills is the definitive authority for the proposition that judicial review is part of the basic structure of the Constitution. The power of courts to examine whether a law or constitutional amendment violates the Constitution cannot be taken away. This principle has been reaffirmed in L. Chandra Kumar v. Union of India (1997), where a 7-judge Bench held that judicial review under Articles 32 and 226 is a basic structure element that cannot be excluded even by specialized tribunals.
Limited amending power is basic structure
The Court held that Parliament's amending power under Article 368 is inherently limited by the basic structure doctrine. Any attempt to make the amending power unlimited — by ousting judicial review or declaring that no limitation exists — itself violates the basic structure. This creates a self-reinforcing limitation: the basic structure doctrine protects itself from amendment.
Balance between fundamental rights and directive principles
The Constitution contemplates a harmony between Part III (fundamental rights — justiciable and enforceable) and Part IV (directive principles — non-justiciable but fundamental in governance). Neither can be given absolute supremacy over the other. Laws implementing directive principles must still respect the essence of fundamental rights. This balance was recognized as a basic structure feature, preventing future Parliaments from using directive principles as a blanket justification to override all fundamental rights.
Significance
Minerva Mills was the first case to actually strike down provisions of a constitutional amendment using the Basic Structure doctrine. While Kesavananda Bharati (1973) articulated the doctrine and Indira Gandhi v. Raj Narain (1975) applied it to the 39th Amendment, Minerva Mills tackled the most audacious attempt to subvert the doctrine itself — the 42nd Amendment's clauses that sought to make Parliament's power unlimited and non-reviewable. By striking down these clauses, the Court demonstrated that the Basic Structure doctrine is not merely an academic principle but a functional check on constitutional authoritarianism. The case is particularly significant because it arose from the aftermath of the Emergency (1975-1977), during which the 42nd Amendment was passed with minimal parliamentary debate while opposition leaders were in prison. Minerva Mills effectively repaired the constitutional damage inflicted during that period.

Frequently asked questions
What provisions of the 42nd Amendment were struck down in Minerva Mills?
The Court struck down two specific provisions: Section 4 (which expanded Article 31C to give blanket protection to any law implementing any directive principle from challenge under Articles 14 and 19) and Section 55 (which inserted clauses (4) and (5) into Article 368, declaring that no constitutional amendment can be questioned in any court and that there is no limitation on Parliament's constituent power). The rest of the 42nd Amendment was not challenged in this case.
Why is Minerva Mills important for the Basic Structure doctrine?
Minerva Mills was the first case to use the Basic Structure doctrine to actually invalidate specific provisions of a constitutional amendment. While Kesavananda Bharati (1973) established the doctrine in principle, Minerva Mills proved it was enforceable. The Court demonstrated that even Parliament's attempt to remove the Basic Structure limitation itself violates basic structure — making the doctrine self-protecting.
What is the relationship between fundamental rights and directive principles after Minerva Mills?
The Court held that the Constitution is founded on the balance between Part III (fundamental rights) and Part IV (directive principles). Neither can be given absolute primacy over the other. Directive principles can be implemented through legislation, but such legislation must respect the essence of fundamental rights. The original Article 31C (protecting only laws implementing Articles 39(b) and (c)) was restored, while the expanded version covering all directive principles was struck down.
Who dissented in Minerva Mills, and on what ground?
Justice P.N. Bhagwati dissented on the question of Section 4 (the expanded Article 31C). He argued that giving primacy to all directive principles over Articles 14 and 19 was a legitimate constitutional choice aimed at achieving socio-economic justice, and did not violate the basic structure. However, the 4:1 majority disagreed, holding that such blanket immunity would destroy the essential balance between fundamental rights and directive principles.
