Introduction
The 'Basic Structure' doctrine is a judicial innovation formulated to limit Parliament's constituent amending power under Article 368. It ensures that the core identity, values, and institutional framework of the Indian Constitution remain indestructible against majoritarian legislative overreach.
1. Kesavananda Bharati v. State of Kerala (1973)
In a landmark 13-judge bench ruling reconciling Article 368 with Article 13, the Supreme Court held that while Parliament can amend any part of the Constitution—including Fundamental Rights—it cannot alter or damage its 'Basic Structure'. Several judges identified non-exhaustive core features:
- Supremacy of the Constitution: The Constitution remains the ultimate legal authority to which all organs of the State are subordinate.
- Republican and Democratic Form of Government: Representative governance and popular sovereignty cannot be abrogated or transformed into an autocracy.
- Secular and Federal Character: Maintenance of state neutrality in religious matters and the constitutional division of powers between the Union and States.
- Separation of Powers: Demarcation of institutional boundaries and checks and balances among the Legislature, Executive, and Judiciary.
- Rule of Law and Dignity of the Individual: Protection of fundamental liberties and governance free from arbitrary exercise of state authority.
2. Minerva Mills v. Union of India (1980)
In this decision, the Supreme Court struck down Section 4 and Section 55 of the 42nd Constitutional Amendment Act, 1976, which had sought to grant unbridled amending powers to Parliament, bar judicial review, and give blanket primacy to all Directive Principles of State Policy (DPSPs) over Fundamental Rights under Articles 14 and 19.
- Harmony and Balance between Part III and Part IV: The Court termed Fundamental Rights and DPSPs the 'bedrock of the Constitution' and 'two wheels of a chariot', ruling that subordinating one to the other destroys the constitutional balance.
- Limited Amending Power: The Court affirmed that Parliament possesses a limited amending power under Article 368. A donee of a limited power cannot expand it into an absolute power to alter its own limits.
- Power of Judicial Review: Reaffirmed as an indispensable basic feature that ensures constitutional amendments and legislative actions remain within substantive constitutional boundaries.
Conclusion
Together, these two landmark judgments established that the amending power cannot be equated with the power to draft an entirely new constitution. They anchored Indian constitutionalism on the supremacy of the Constitution rather than parliamentary sovereignty, providing an enduring safeguard for democratic governance.
