Introduction
The Indian Constitution designates the higher judiciary—the Supreme Court under Article 32 and High Courts under Article 226—as its ultimate interpreter and protector. Through its powers of judicial review and constitutional interpretation, the judiciary acts as a sentinel on the qui vive, safeguarding constitutional supremacy, the rule of law, and the fundamental rights of citizens.
1. Upholding the Basic Structure Doctrine
The judiciary prevents constitutional erosion and dismemberment by restricting Parliament's amending powers under Article 368.
- Preventing Arbitrary Amendments: In Kesavananda Bharati v. State of Kerala (1973), the Supreme Court established that Parliament cannot alter foundational features such as secularism, democracy, and judicial independence.
- Checking Legislative Immunity: In the I.R. Coelho case (2007), the court held that laws inserted into the Ninth Schedule post-April 24, 1973, are not immune from judicial scrutiny if they infringe upon the basic structure.
2. Safeguarding Fundamental Rights
The judiciary acts as a bulwark against executive and legislative overreach by creatively interpreting and enforcing Part III of the Constitution.
- Expanding the Scope of Article 21: The judiciary expanded the right to life to include the right to dignity, a clean environment, and privacy, most notably in K.S. Puttaswamy v. Union of India (2017).
- Ensuring Democratic Transparency: In 2024, the Supreme Court struck down the Electoral Bonds scheme as unconstitutional, citing violations of voters' right to information under Article 19(1)(a).
3. Protecting the Federal Equilibrium
The judiciary acts as an impartial arbiter in Centre-State disputes, maintaining federal balance.
- Regulating Article 356: In S.R. Bommai v. Union of India (1994), the Supreme Court framed strict guidelines to prevent the arbitrary imposition of President's Rule, establishing that proclamation of emergency is subject to judicial review.
4. Enforcing Constitutional Checks and Balances
Through the power of judicial review embedded in Article 13, the judiciary invalidates any legislative statute or executive order that is ultra vires the constitutional text, ensuring all organs function strictly within their defined spheres.
Conclusion
To remain effective, the judiciary must balance proactive constitutional protection, such as Public Interest Litigation (PIL), with institutional restraint to avoid judicial overreach. Addressing systemic challenges like judicial vacancies and case pendency will further consolidate its stature as the constitutional bedrock of Indian democracy.
