When ordinary citizens cannot reach the courts, the courts reach out to them — that is the spirit of Public Interest Litigation (PIL) and judicial activism. For CDS & OTA, this topic blends fact-recall with concept. Expect questions on what activism means, who introduced PIL, and the landmark judgments — from Kesavananda Bharati to Vishaka — that every aspirant must memorise cold.
Why This Topic Matters in CDS Polity
Polity is among the highest-scoring areas of the CDS and OTA General Studies paper, and questions on the judiciary appear in almost every cycle. Within the judiciary, examiners love the conceptual trio of judicial review, judicial activism and PIL, plus the landmark cases attached to each.
The good news: this is a memory-friendly topic. Most questions ask you to match a case with its outcome, identify the judge or article involved, or define a term. Once you have firmly fixed the famous cases and a few core definitions, you can answer these in seconds, without any guesswork.
This single page also has carry-over value. Concepts here connect directly to chapters on Fundamental Rights, the Directive Principles and constitutional amendments. So the hours you invest learning these landmark cases pay off across the whole Polity portion of your General Studies paper, and even in your SSB interview discussions on the Constitution.
Three ideas often get mixed up. Judicial review is the power to test laws against the Constitution. Judicial activism is the willingness to use that power boldly. PIL is the tool that lets the public bring public-interest matters to court.
Judicial Review: The Foundation
Everything in this topic rests on judicial review — the power of the Supreme Court and High Courts to examine the constitutionality of laws and executive orders. If a law violates the Constitution, the court can declare it void.
Although the phrase “judicial review” is not written in the Constitution, the power flows from several articles, especially Article 13 (laws inconsistent with Fundamental Rights are void), Article 32 (Supreme Court’s power to enforce rights) and Article 226 (High Courts’ writ power).
Judicial review in India is based on the principle of “procedure established by law” (borrowed from Japan), not the American “due process of law” — though the Maneka Gandhi case later widened its scope. Article 13 is the textual anchor for striking down unconstitutional laws.
Judicial Activism: Meaning and Origin
Judicial activism means the proactive role played by the judiciary in protecting citizens’ rights and promoting justice, even where the legislature and executive have failed to act. An “activist” court does not wait passively; it interprets the Constitution dynamically to fill gaps and check abuse of power.
The term was coined in the United States, but in India it took firm root in the late 1970s and 1980s, when the Supreme Court relaxed locus standi rules and expanded the meaning of Article 21 (right to life). Justices like P.N. Bhagwati and V.R. Krishna Iyer are closely associated with this era.
How activism shows up
- Expanding Fundamental Rights (e.g., reading the right to a clean environment, education and privacy into Article 21).
- Issuing detailed guidelines where laws are silent (as in the Vishaka case).
- Monitoring executive action through continuing mandamus in PILs.
Do not equate judicial activism with judicial review. Review is a neutral power that even a restrained court uses; activism is a style or attitude of using that power expansively. All activism involves review, but not all review is activism.
Judicial Restraint and Judicial Overreach
The opposite of activism is judicial restraint — the view that judges should respect the separation of powers and avoid intruding into the domains of the legislature and executive. A restrained court defers to elected representatives on matters of policy.
When activism goes too far — when courts effectively start making policy or administering government — critics call it judicial overreach. This is seen as upsetting the constitutional balance among the three organs of the State.
Remember the spectrum: Restraint → Review → Activism → Overreach. CDS questions sometimes give a definition and ask you to name the term; restraint and overreach are the two extremes.
Public Interest Litigation (PIL): What It Is
Public Interest Litigation is litigation undertaken to secure public interest — to protect the rights of those who, because of poverty, ignorance or disadvantage, cannot approach the court themselves. It is the single most powerful instrument of judicial activism in India.
The key innovation of PIL is the relaxation of the traditional rule of locus standi. Ordinarily, only the person whose right is violated can go to court. Under PIL, any public-spirited citizen or organisation can file a petition on behalf of an aggrieved group that cannot do so itself.
Who pioneered PIL
PIL emerged in India in the late 1970s and early 1980s, with Justices P.N. Bhagwati and V.R. Krishna Iyer widely credited as its architects. The Court even accepted petitions sent through a simple letter or postcard — the so-called “epistolary jurisdiction.”
PIL can be filed in the Supreme Court under Article 32 or in a High Court under Article 226. It targets matters of public concern — environment, prisoners’ rights, bonded labour, corruption — not private disputes.
Key Features and Limits of PIL
Several features make PIL distinct from ordinary litigation:
- Relaxed locus standi — a third party can litigate for the affected group.
- Flexible procedure — even a letter to the court can be treated as a writ petition.
- Inquisitorial approach — the court may appoint commissions to gather facts, instead of relying only on the parties.
- Continuing mandamus — the court keeps monitoring compliance over time.
PIL has its limits too. The Supreme Court has cautioned against frivolous or publicity-driven PILs — sometimes mocked as “Private Interest” or “Publicity Interest” Litigation. Courts may impose costs to discourage misuse and have issued internal guidelines to filter out petitions that have no genuine public element. The aim is to keep PIL a shield for the weak, not a weapon for the mischievous.
PIL is not a fourth tier of appeal and cannot be used to settle personal grievances or business rivalries. Examiners may test whether you know that PIL is meant for genuine public interest only.
Landmark Judgments: Basic Structure and Rights
These cases form the backbone of objective questions. Learn the case name and its one-line outcome.
Kesavananda Bharati (1973)
The most important constitutional case. The Supreme Court held that Parliament can amend the Constitution but cannot alter its “basic structure.” This Basic Structure Doctrine is the ultimate limit on the amending power under Article 368.
Maneka Gandhi (1978)
The Court ruled that the procedure under Article 21 must be just, fair and reasonable — effectively importing “due process” and vastly widening the right to life and personal liberty.
Minerva Mills (1980)
Reaffirmed the basic structure doctrine and held that the balance between Fundamental Rights and Directive Principles is itself part of the basic structure.
Kesavananda Bharati = Basic Structure Doctrine. If a single case is asked in your CDS paper, it is most likely this one. The Golaknath case (1967) preceded it but was superseded by Kesavananda.
Landmark Judgments: PIL and Activism
These cases show judicial activism through PIL in action.
Hussainara Khatoon (1979)
The first reported PIL in India. It exposed the plight of undertrial prisoners in Bihar and established the right to speedy trial as part of Article 21.
S.P. Gupta (1981)
Often called the “Judges Transfer case,” it formally liberalised locus standi, opening the door for PIL by any public-spirited person.
Vishaka v. State of Rajasthan (1997)
In the absence of any law, the Supreme Court laid down binding guidelines against sexual harassment of women at the workplace — a classic example of activism filling a legislative vacuum. These were later codified into the 2013 Act.
M.C. Mehta cases
A series of environmental PILs that protected the Taj Mahal, the Ganga and Delhi’s air, and developed the “polluter pays” and “absolute liability” principles.
Link each case to a keyword: Hussainara → speedy trial; Vishaka → workplace harassment; M.C. Mehta → environment; S.P. Gupta → locus standi. Keyword association is the fastest way to crack PYQs.
Worked Example: Matching Cases to Concepts
Let us practise the most common question format — matching a case with its principle.
Match each case with the doctrine or right it is famous for, then identify the odd one out that is not a PIL.
This shows why you must store both the outcome and the type of case — examiners frequently test the distinction between a PIL and an ordinary writ petition.
Common Mistakes to Avoid
A few traps reappear in CDS and OTA papers. Guard against them:
- Confusing Article 32 (Supreme Court writs) with Article 226 (High Court writs). Note that Article 226 is wider — High Courts can issue writs for any legal right, not just Fundamental Rights.
- Assuming activism is always positive. Examiners may frame it as a concern about overreach and separation of powers.
- Mixing up retirement ages and case years — remember Kesavananda 1973, Vishaka 1997.
- Thinking PIL can be filed for personal benefit — it cannot.
Golaknath (1967) is not the basic structure case. Golaknath said Parliament could not amend Fundamental Rights at all; Kesavananda (1973) overruled it and gave the more balanced basic structure doctrine. Swapping these two is a classic exam error.
Previous-Year Style Practice
Test yourself with an exam-style question before revising.
Q. In the context of the Indian judiciary, the doctrine of “Basic Structure” was propounded by the Supreme Court in which of the following cases?
Answer: Kesavananda Bharati v. State of Kerala (1973). The Court held that Parliament can amend any part of the Constitution under Article 368 but cannot destroy or alter its basic structure, such as supremacy of the Constitution, the rule of law and judicial review.
Common “basic structure” elements named by courts include: supremacy of the Constitution, secularism, federalism, separation of powers, judicial review, and free and fair elections. Any one of these can be the answer to a fill-in-the-blank question.
Quick Revision
- Judicial review = power to test laws against the Constitution (Articles 13, 32, 226).
- Judicial activism = bold, proactive use of that power; opposite is restraint; excess is overreach.
- PIL = relaxed locus standi; any citizen can file for public interest under Article 32 (SC) or 226 (HC). Pioneers: Bhagwati & Krishna Iyer.
- Kesavananda (1973) → Basic Structure; Maneka (1978) → fair procedure under Art 21.
- Hussainara (1979) → speedy trial; Vishaka (1997) → workplace harassment; M.C. Mehta → environment.

Frequently asked questions
What is the difference between judicial activism and judicial review?
Judicial review is the neutral power of courts to test whether laws conform to the Constitution. Judicial activism is the proactive attitude of using that power expansively to protect rights and fill gaps left by the legislature or executive.
Who introduced the concept of PIL in India?
Public Interest Litigation was pioneered in the late 1970s and 1980s by Justices P.N. Bhagwati and V.R. Krishna Iyer, who relaxed the rule of locus standi so that any public-spirited person could approach the court on behalf of the disadvantaged.
Under which articles can a PIL be filed?
A PIL can be filed in the Supreme Court under Article 32 or in a High Court under Article 226. Article 226 is wider, as High Courts can issue writs for the enforcement of any legal right, not only Fundamental Rights.
Why is the Kesavananda Bharati case so important for CDS?
It established the Basic Structure Doctrine in 1973, holding that Parliament can amend the Constitution but cannot alter its basic structure. It is the single most frequently tested constitutional case in the CDS and OTA Polity section.
What is judicial overreach?
Judicial overreach is excessive judicial activism, where courts effectively make policy or take over administrative functions that belong to the legislature or executive, thereby disturbing the constitutional separation of powers.
