Introduction
As the designated 'guardian of the Constitution' under Part V (Articles 124–147), the Supreme Court of India ensures constitutional supremacy, institutional checks and balances, and the rule of law. It operates as the final arbiter of constitutional interpretation and a counter-majoritarian institution protecting foundational democratic values.
Key Roles in Protecting the Constitution
- Safeguarding Constitutional Identity (Basic Structure Doctrine): In Kesavananda Bharati v. State of Kerala (1973), the Supreme Court circumscribed Parliament's amending power under Article 368, holding that the core identity or 'Basic Structure' of the Constitution cannot be abrogated. This principle was further reinforced in Minerva Mills (1980) to maintain a balance between Fundamental Rights and Directive Principles.
- Defending Fundamental Rights: Under Article 32, termed the 'heart and soul' of the Constitution by Dr. B.R. Ambedkar, the Court exercises writ jurisdiction to remedy constitutional infringements. It has widened civil liberties by reading 'due process of law' into Article 21 (Maneka Gandhi, 1978) and recognizing privacy as an intrinsic fundamental right (K.S. Puttaswamy, 2017).
- Maintaining Federal Equilibrium: Under its exclusive Original Jurisdiction under Article 131, the Court adjudicates legal disputes between the Centre and States or between States. In S.R. Bommai v. Union of India (1994), it established federalism as a basic feature and curbed the arbitrary imposition of President's Rule under Article 356.
- Securing Complete Justice: Utilizing its plenary powers under Article 142, the Supreme Court can pass decrees or orders necessary to do complete justice in any cause or matter, often stepping in to protect constitutional rights and resolve institutional vacuums.
Conclusion
By balancing proactive judicial protection with institutional self-restraint, the Supreme Court ensures that the Indian Constitution operates as an enduring, living document capable of protecting democratic governance and the fundamental rights of citizens.
