Introduction
Former Chief Justice of India D.Y. Chandrachud termed the Basic Structure Doctrine the 'North Star' of Indian democracy. Evolved by the Supreme Court in the landmark Kesavananda Bharati case (1973), the doctrine establishes that Parliament's constituent power to amend the Constitution under Article 368 cannot be utilized to alter or destroy its foundational identity.
Evolution of the Constitutional Shield
The doctrine emerged through an ongoing institutional dialogue regarding the scope of amending power under Article 368:
- Early Plenary Authority: In Shankari Prasad (1951) and Sajjan Singh (1965), the Supreme Court held that Parliament possessed plenary power to amend any part of the Constitution, including Fundamental Rights.
- Rigid Restriction: The pendulum swung in the Golaknath case (1967), where the Court ruled that Fundamental Rights could not be abridged by constitutional amendments under Article 13.
- The Harmonious Equilibrium: The Kesavananda Bharati (1973) bench struck a middle ground, affirming that while Parliament can amend any provision of the Constitution, it cannot alter its 'basic structure'.
Mechanisms by Which the Doctrine Prevents Misuse
The Basic Structure Doctrine acts as an active constraint against legislative overreach in multiple ways:
- Nullifying Absolute Power: In Minerva Mills (1980), the Supreme Court invalidated clauses added to Article 368 by the 42nd Amendment that sought to grant Parliament limitless amending authority and exclude judicial review under Articles 32 and 226.
- Eliminating Blanket Immunities: In the I.R. Coelho case (2007), the Court ruled that laws placed in the Ninth Schedule after April 24, 1973, are not immune from judicial scrutiny if they infringe upon fundamental rights that form part of the basic structure.
- Preserving Institutional Separation: The invalidation of the 99th Constitutional Amendment and the National Judicial Appointments Commission (NJAC) Act in 2015 demonstrated how the doctrine shields the independence of the judiciary from executive and legislative dominance.
Conclusion
While ordinary legislation requires a simple majority, constitutional amendments demand a special majority under Article 368. The Basic Structure Doctrine ensures that even an overwhelming parliamentary supermajority cannot convert a constituted body into a sovereign one, thereby safeguarding constitutional supremacy over transient majoritarian impulses.
