Introduction
The Basic Structure Doctrine (BSD), established in the landmark Kesavananda Bharati case (1973), affirms that Parliament's constituent power under Article 368 cannot alter or destroy the foundational ethos of the Indian Constitution. By asserting constitutional supremacy over absolute parliamentary sovereignty, the doctrine provides an essential check against majoritarian legislative overreach.
Reaffirming Limits on Parliamentary Sovereignty in Recent Jurisprudence
Recent Supreme Court decisions have consistently demonstrated that parliamentary legislation and constitutional amendments are subject to substantive judicial review anchored in foundational constitutional principles:
- Free and Fair Elections: In Association for Democratic Reforms (ADR) v. Union of India (2024), the Supreme Court struck down the Electoral Bonds Scheme, ruling that anonymous political funding infringes the voters' right to information under Article 19(1)(a) and impairs the democratic basic structure.
- Independence of the Judiciary: In the NJAC Case (Supreme Court Advocates-on-Record Association v. Union of India, 2015), the 99th Constitutional Amendment Act was invalidated to maintain judicial independence (Article 50) and prevent executive primacy in judicial appointments.
- Federalism: In Union of India v. Rajendra N. Shah (2021), key provisions of the 97th Constitutional Amendment Act regarding cooperative societies were struck down because Parliament bypassed the mandatory ratification by state legislatures under the proviso to Article 368(2).
- Separation of Powers: In Madras Bar Association v. Union of India (2021), the Court annulled tribunal reforms that allowed executive discretion in judicial tenures, reinforcing institutional separation of powers.
Critical Analysis: Constitutional Restraint versus Judicial Overreach
While the Basic Structure Doctrine acts as an indispensable bulwark against potential legislative authoritarianism, it attracts significant constitutional and institutional scrutiny:
- Subjective Vagueness: Because the Constitution does not define or enumerate the 'basic structure', the doctrine remains judge-made and subjective. Critics argue this risks leading to a 'tyranny of the unelected', potentially stalling legitimate legislative mandates passed by democratically elected representatives.
- Blurring Amending and Ordinary Powers: The application of the doctrine has occasionally transcended constitutional amendments (constituent power) to scrutinise ordinary legislation (legislative power), expanding judicial review beyond its traditional ambit.
- Counter-Majoritarian Dilemma: Repeated nullification of broad legislative consensus can create institutional friction between the judiciary and Parliament, testing the doctrine of separation of powers.
Conclusion
As held in the Minerva Mills case (1980), the Indian Constitution is founded on a delicate balance between the legislature, executive, and judiciary. The Basic Structure Doctrine should function primarily as a defensive shield to preserve foundational constitutional values rather than as an expansive instrument that circumvents democratic lawmaking.
