Most aspirants use the terms “judicial review” and “judicial activism” as if they mean the same thing. They do not. Confusing these two concepts in your Mains answer can cost you marks, because the examiner is specifically looking for clarity on how India’s judiciary operates within — and sometimes beyond — its constitutional boundaries.
This article breaks down both concepts from scratch, explains their constitutional roots, compares them side by side, and shows you exactly how to use this distinction in your UPSC answers. Whether you are preparing for Prelims or writing a GS-II Mains answer, this will serve as a solid foundation.
Where This Topic Sits in the UPSC Syllabus
This topic falls squarely under GS Paper II (Governance, Constitution, Polity). The syllabus explicitly mentions “Structure, organization and functioning of the Judiciary.” Both judicial review and judicial activism are tested regularly — sometimes directly, sometimes through questions on PIL, separation of powers, or judicial overreach.
| Exam Stage | Paper | Syllabus Section |
|---|---|---|
| Prelims | General Studies | Indian Polity — Judiciary, Constitutional provisions |
| Mains | GS-II | Structure, organization, functioning of Judiciary; Separation of Powers |
| Mains | GS-II | Government policies and interventions; Governance issues |
Related topics you should study alongside this include: Basic Structure Doctrine, Public Interest Litigation, Judicial Overreach, Separation of Powers, and Constitutional Amendments. UPSC has asked questions on these areas at least 8-10 times in the past 15 years across Prelims and Mains.
What Exactly Is Judicial Review?
Judicial review is the power of the judiciary to examine laws passed by the legislature and actions taken by the executive. If a law or action violates the Constitution, the court can declare it void. Think of it as a quality check — the judiciary ensures that no branch of government crosses the limits set by the Constitution.
In India, this power is not stated in one single article. It flows from several provisions. Article 13 says that any law inconsistent with fundamental rights shall be void. Articles 32 and 226 empower the Supreme Court and High Courts respectively to issue writs for enforcing rights. Article 245 defines the territorial and subject-matter limits of Parliament and state legislatures. Together, these provisions give Indian courts the authority to review legislation.
The concept has American roots. In the famous 1803 case of Marbury v Madison, the US Supreme Court established the principle that courts can strike down unconstitutional laws. India adopted this principle but embedded it directly into the constitutional text, unlike the US where it evolved through case law.
Judicial review is a settled, constitutional power. No one seriously disputes that courts have this authority. It is part of the design of our democracy — a check against arbitrary power.
What Exactly Is Judicial Activism?
Judicial activism is a different phenomenon altogether. It refers to situations where the judiciary goes beyond its traditional role of interpreting the law and actively steps into governance — filling policy gaps, directing the executive to act, or expanding the meaning of rights through creative interpretation.
The best example is the Public Interest Litigation (PIL) movement that began in the late 1970s and 1980s under justices like P.N. Bhagwati and V.R. Krishna Iyer. They relaxed the rule of “locus standi” — the requirement that only an affected person can approach the court. Under judicial activism, any public-spirited citizen could write a letter to the court, and that letter could be treated as a petition.
Through judicial activism, the Supreme Court has directed governments to close polluting industries (as in the M.C. Mehta cases), ordered mid-day meal schemes in schools, set guidelines on sexual harassment at workplaces (Vishakha v State of Rajasthan, 1997), and even monitored CBI investigations. These are areas that traditionally belong to the executive or legislature. The court stepped in because those branches were not acting.
Judicial activism is not a constitutional power. It is a judicial philosophy — a choice that judges make about how expansively they should interpret their role.
The Core Distinction — Side by Side
Let me lay out the difference clearly. Judicial review asks: “Is this law constitutional?” Judicial activism asks: “The government is not doing its job — should the court step in?” One is a check on power. The other is an exercise of power in a vacuum left by other branches.
Judicial review is reactive — someone challenges a law, and the court examines it. Judicial activism is often proactive — the court may take up an issue on its own (suo motu) or through a PIL, even when no specific law is being challenged.
Judicial review preserves the separation of powers. Each branch stays in its lane. Judicial activism can blur these boundaries. When the Supreme Court directs the government to implement a particular policy, it is effectively doing the executive’s job. This is why critics call it judicial overreach.
However, supporters argue that judicial activism is necessary in a country like India where millions of people lack access to the executive and legislature. When the state fails, the court becomes the last hope. The PIL movement has delivered justice to bonded labourers, undertrials, and environmental victims who had no other recourse.
Landmark Cases You Must Know
Kesavananda Bharati v State of Kerala (1973) — This is the most important judicial review case in Indian history. The Supreme Court held that Parliament can amend the Constitution but cannot alter its “basic structure.” This put a permanent limit on legislative power. The basic structure doctrine itself was a product of judicial interpretation, which some scholars consider an act of judicial activism within the framework of judicial review.
Maneka Gandhi v Union of India (1978) — The court expanded the meaning of Article 21 (Right to Life) to include the right to live with dignity. This was judicial activism through interpretation. It opened the door for dozens of rights — right to education, right to clean environment, right to privacy — to be read into Article 21.
Vishakha v State of Rajasthan (1997) — In the absence of any law on sexual harassment at the workplace, the Supreme Court laid down binding guidelines. This is a textbook example of judicial activism filling a legislative vacuum. These guidelines operated as law until Parliament passed the Sexual Harassment of Women at Workplace Act in 2013.
L. Chandra Kumar v Union of India (1997) — The court held that judicial review under Articles 226 and 32 is part of the basic structure of the Constitution. This means Parliament cannot take away the power of judicial review through any amendment. This case firmly rooted judicial review as an untouchable constitutional feature.
How to Use This Distinction in Your UPSC Answers
When a question asks you to “distinguish between judicial review and judicial activism,” structure your answer around three pillars: constitutional basis (review is textual, activism is philosophical), scope (review is limited to constitutionality, activism extends to governance), and impact on separation of powers (review reinforces it, activism sometimes challenges it).
If the question asks you to “critically examine judicial activism in India,” do not just praise it. Mention both its achievements (PIL movement, environmental protection, human rights) and its problems (judicial overreach, unelected judges making policy, undermining democratic accountability). A balanced answer scores better than a one-sided one.
Always cite cases. A Mains answer on this topic without at least two case names will look incomplete. Kesavananda Bharati for judicial review and Vishakha for judicial activism are the minimum you should mention.
Key Points to Remember for UPSC
- Judicial review is a constitutional power derived from Articles 13, 32, 226, and 245. It checks whether laws and executive actions conform to the Constitution.
- Judicial activism is a judicial philosophy where courts proactively address governance failures, often through PILs and expansive interpretation of fundamental rights.
- Judicial review strengthens separation of powers; judicial activism can sometimes blur it — this is the key tension examiners want you to analyse.
- The Basic Structure Doctrine (Kesavananda Bharati, 1973) is the most significant outcome of judicial review in India. It limits Parliament’s amending power permanently.
- The PIL movement of the 1980s under Justices Bhagwati and Krishna Iyer is the foundation of judicial activism in India.
- L. Chandra Kumar (1997) established that judicial review is part of the basic structure and cannot be removed by any constitutional amendment.
- Judicial activism is praised for delivering justice to marginalised groups but criticised for leading to judicial overreach and creating an accountability gap.
- For Mains, always present both sides — the necessity of activism in a developing democracy and the democratic concern of unelected judges making policy decisions.
Understanding this distinction gives you an analytical edge across multiple GS-II topics — from PIL to separation of powers to governance reforms. As a next step, read the Kesavananda Bharati and Vishakha judgments in summary form and practice writing a 250-word answer distinguishing the two concepts. That single exercise will make this topic exam-ready for you in 2026.
