1. Role of Judiciary and Judicial Review (basic)
Hello there! To understand Public Interest Litigation (PIL), we must first grasp the foundational power that makes it possible:
Judicial Review. Think of the Indian Constitution as the ultimate 'rulebook' of the land. In a democracy, the Legislature makes laws and the Executive implements them, but someone needs to ensure they don't break the rules of this rulebook. That 'watchdog' is the Judiciary.
Judicial Review is the power of the Supreme Court and High Courts to examine the constitutionality of legislative enactments and executive orders. If a law or order is found to violate the Constitution, the courts can declare it
ultra-vires (beyond their power), illegal, and void. As the
guardian of the Constitution and the
guarantor of Fundamental Rights, the Judiciary uses this power to protect citizens from any arbitrary state action
Indian Polity, Chapter 26: Supreme Court, p.290.
Interestingly, the phrase 'Judicial Review' is
nowhere mentioned in the Constitution itself! However, the power is explicitly granted through various provisions, most notably
Article 13, which states that any law inconsistent with Fundamental Rights shall be void
Indian Polity, Chapter 27: Judicial Review, p.297. This power extends to both Central and State governments, ensuring that no authority oversteps its constitutional boundaries
Indian Polity, Chapter 34: High Court, p.360.
| Feature |
Description |
| Primary Goal |
To maintain the supremacy of the Constitution and protect Fundamental Rights. |
| Scope |
Covers both legislative acts (laws) and executive actions (orders/rules). |
| Constitutional Basis |
Implicit in Articles 13, 32, 131-136, 226, and 246. |
Key Takeaway Judicial Review is the 'checking' power of the courts that allows them to invalidate any law or government action that contradicts the Constitution.

2. Genesis of Public Interest Litigation (PIL) in India (basic)
Concept: Genesis of Public Interest Litigation (PIL) in India
3. Traditional Rule of Locus Standi (intermediate)
In the traditional legal world, the rule of
locus standi (literally meaning 'a place of standing') was quite strict and individualistic. It dictated that
only the person whose own legal rights were directly violated—the
'aggrieved person'—had the legal authority to approach a court for a remedy. If a neighbor’s rights were being trampled upon, you could not file a case on their behalf, even if you wanted to help. This traditional rule ensured that courts weren't flooded with meddlesome bystanders, but it also created a massive barrier for those who were too poor, illiterate, or socially disadvantaged to fight for themselves. This individualistic approach is most clearly seen in the standard application of
Article 32, where an aggrieved person moves the Supreme Court specifically for the enforcement of their Fundamental Rights
Indian Polity, Fundamental Rights, p.106.
However, as India’s democracy matured, the judiciary realized that a strict adherence to 'locus standi' was denying justice to millions. The transformation began when the courts decided to liberalize this rule. The logic was simple: if a person or a group of persons is unable to reach the court due to poverty or disability, any public-spirited citizen or social action group should be allowed to step into their shoes. This shift effectively 'democratized' the judicial process, allowing the court to address grievances on behalf of the deprived and marginalized who cannot vindicate their own rights Indian Polity, Public Interest Litigation, p.311.
The comprehensive legal foundation for this expansion was laid down in the landmark case of S.P. Gupta v. Union of India (1981), also known as the 'Judges’ Transfer Case'. While earlier cases like Hussainara Khatoon (1979) were the first to be recognized as PILs, it was Justice P.N. Bhagwati in the S.P. Gupta case who formally articulated that any member of the public acting bona fide (in good faith) could invoke the court's jurisdiction to protect the legal or constitutional rights of those who are unable to do so themselves. This effectively replaced the old 'aggrieved person' rule with a more inclusive 'representative' standing.
| Feature |
Traditional Locus Standi |
Liberalized (PIL) Locus Standi |
| Who can sue? |
Only the person whose rights are directly infringed. |
Any public-spirited citizen acting in good faith. |
| Primary Objective |
Redressal of individual private wrongs. |
Redressal of public wrongs or injury to the marginalized. |
| Legal Basis |
Strict interpretation of Article 32/226. |
Broad interpretation (e.g., S.P. Gupta Case, 1981). |
Key Takeaway The traditional rule of locus standi restricts court access to the 'aggrieved person,' but in India, this rule was relaxed (liberalized) through cases like S.P. Gupta to allow third parties to seek justice for the marginalized.

4. Judicial Activism vs. Judicial Restraint (intermediate)
To understand the expansion of justice in India, we must look at the two competing philosophies that guide how judges exercise their power: Judicial Activism and Judicial Restraint. Think of these as two different mindsets a judge can adopt when interpreting the Constitution. While Judicial Activism (also known as 'judicial dynamism') involves a proactive and assertive role in protecting citizen rights and forcing the executive or legislature to perform their duties, Judicial Restraint is its antithesis, emphasizing self-control and strict adherence to law as it is written Indian Polity, M. Laxmikanth (7th ed.), Chapter 28: Judicial Activism, p.303.
The concept of Judicial Activism originated in the USA and was coined by Arthur Schlesinger Jr. in 1947. In India, it gained momentum in the mid-1970s through the efforts of visionary judges like Justice P.N. Bhagwati and Justice V.R. Krishna Iyer. These judges believed that the law should be a tool for social change, moving beyond mere judicial review (validating laws) to actively moulding the law to suit changing social and economic scenarios. Conversely, proponents of Judicial Restraint argue that judges are not elected to make policy; their role should be limited to saying what the law is, leaving law-making to the Legislature and Executive Indian Polity, M. Laxmikanth (7th ed.), Chapter 28: Judicial Activism, p.307.
It is helpful to compare these two approaches side-by-side to see how they impact the balance of power:
| Feature |
Judicial Activism |
Judicial Restraint |
| Role of Judge |
Proactive; moves beyond precedent to promote social justice. |
Passive; adheres strictly to precedent and constitutional text. |
| Law-making |
Judges participate in policy-making to fill legislative gaps. |
Judges avoid law-making, respecting the domain of the legislature. |
| Motivation |
Progressive social policies and protecting the marginalized. |
Maintaining the separation of powers and judicial stability. |
However, there is a fine line between activism and Judicial Overreach (or judicial adventurism). The courts have often warned that while they must protect rights, they should not embarrass administrative authorities or take over tasks requiring specialized administrative expertise. As the saying goes, activism must be done within the system of "historically validated restraints" Indian Polity, M. Laxmikanth (7th ed.), Chapter 28: Judicial Activism, p.308.
Key Takeaway Judicial Activism is the proactive use of judicial power to promote social justice, while Judicial Restraint is the philosophy that judges should limit their power to interpreting existing laws without encroaching on the legislature's policy-making role.

5. Writ Jurisdiction: Articles 32 and 226 (intermediate)
In our journey toward understanding Public Interest Litigation (PIL), we must first master the "Engine Rooms" of the Indian Constitution: Article 32 and Article 226. Without these, our Fundamental Rights would be mere words on paper. As Dr. B.R. Ambedkar famously said, Article 32 is the "Heart and Soul" of the Constitution because it provides a guaranteed, effective, and summary remedy for the protection of our rights Indian Polity, M. Laxmikanth, Fundamental Rights, p.98.
While both the Supreme Court (SC) and the High Courts (HC) have the power to issue Writs (legal orders like Habeas Corpus or Mandamus), their jurisdictions are not identical. The Supreme Court is specifically constituted as the defender and guarantor of Fundamental Rights. Under Article 32, a citizen can go directly to the SC, and because this right is itself a Fundamental Right, the SC cannot refuse to hear the plea. In contrast, the High Court's power under Article 226 is discretionary; however, it is also wider in scope. While the SC can only issue writs to enforce Fundamental Rights (Part III), a High Court can issue them for Fundamental Rights and for "any other purpose" (i.e., ordinary legal rights) Indian Polity, M. Laxmikanth, Supreme Court, p.291.
One of the most critical aspects to remember for your exams is that this writ jurisdiction is so fundamental to our democracy that it forms part of the Basic Structure of the Constitution. In the L. Chandra Kumar case (1997), the Court ruled that this power cannot be taken away even by a Constitutional Amendment Indian Polity, M. Laxmikanth, High Court, p.358. This legal "shield" ensures that the judiciary always remains accessible to check the arbitrary actions of the State.
| Feature |
Article 32 (Supreme Court) |
Article 226 (High Court) |
| Scope |
Narrower: Only for Fundamental Rights. |
Wider: For Fundamental Rights and legal rights. |
| Nature |
Mandatory (It is a Fundamental Right). |
Discretionary. |
| Territory |
Whole of India. |
Within its state/territorial jurisdiction. |
Key Takeaway While the Supreme Court is the ultimate protector of Fundamental Rights, the High Court actually possesses a broader writ jurisdiction because it can address violations of both fundamental and ordinary legal rights.

6. Early Breakthroughs: Hussainara Khatoon Case (intermediate)
To understand the evolution of
Public Interest Litigation (PIL), we must look at the spark that started the fire: the
Hussainara Khatoon v. Home Secretary, State of Bihar (1979) case. Before this, the Indian legal system followed the strict rule of
locus standi, meaning only the person whose rights were violated could approach the court. This case shattered that barrier. It began when a series of newspaper articles highlighted the plight of thousands of "undertrials" in Bihar—prisoners who had been languishing in jail for periods longer than the maximum sentence they would have received if they had actually been convicted
Indian Constitution at Work, Political Science Class XI (NCERT 2025 ed.), JUDICIARY, p.136.
Deeply moved by these reports, an advocate named
Kapila Hingorani filed a petition on behalf of these prisoners. This was revolutionary because the prisoners themselves hadn't moved the court; a "public-spirited" third party did. The Supreme Court accepted the petition, effectively marking the birth of PIL in India. The Court's intervention led to the release of nearly 40,000 undertrials, transforming the judiciary from a passive arbiter into an active protector of the marginalized.
The most significant constitutional breakthrough of this case was the interpretation of
Article 21 (Right to Life and Personal Liberty). The Court declared that the
"Right to a speedy trial" is an integral part of Article 21
Introduction to the Constitution of India, D. D. Basu (26th ed.), FUNDAMENTAL RIGHTS AND FUNDAMENTAL DUTIES, p.132. This expanded the scope of personal liberty, ensuring that the state cannot keep individuals in indefinite detention without trial
Introduction to the Constitution of India, D. D. Basu (26th ed.), FUNDAMENTAL RIGHTS AND FUNDAMENTAL DUTIES, p.135.
Early 1979 — Newspaper reports expose the plight of undertrials in Bihar jails.
1979 (Hussainara Khatoon Case) — The Supreme Court hears the first major PIL and orders the release of thousands.
1981 (S.P. Gupta Case) — The Court provides a comprehensive legal foundation for "liberalized standing," solidifying PIL doctrine.
Key Takeaway The Hussainara Khatoon case was the first major breakthrough in PIL history, establishing that any citizen can approach the court for the rights of the poor and recognizing the "Right to a Speedy Trial" under Article 21.

7. The S.P. Gupta Case and the 'First Judges Case' (exam-level)
The case of
S.P. Gupta v. Union of India (1981), popularly known as the
'First Judges Case', is a watershed moment in Indian legal history for two distinct reasons: it reshaped the process of judicial appointments and, more importantly for our study, it provided the
legal foundation for Public Interest Litigation (PIL). Before this case, the court followed the strict traditional rule of
locus standi, which meant that only a person whose own fundamental rights were violated could approach the court for a remedy. In this landmark judgment,
Justice P.N. Bhagwati dismantled this barrier, ruling that any public-spirited citizen or social action group could move the court on behalf of those who, due to poverty, helplessness, or disability, were unable to seek justice themselves
Indian Polity, M. Laxmikanth, Chapter 29, p. 309.
While earlier cases like
Hussainara Khatoon (1979) were technically the first PILs, it was the
S.P. Gupta case that articulated the
comprehensive legal theory behind expanding standing to third parties. The court held that where a legal wrong is done to a person or a class of persons who cannot reach the court, any member of the public acting
bona fide (in good faith) can maintain an action for judicial redress. This innovation democratized the Indian judiciary, transforming it from a venue for private disputes into an instrument for social change.
In the context of judicial administration, this case is also famous for the
'Consultation vs. Concurrence' debate regarding the appointment of judges. At the time, the Supreme Court held that the term 'consultation' used in the Constitution did not mean 'concurrence' (agreement). This effectively gave the
Executive (the President) the final say in judicial appointments, provided the consultation with the Chief Justice of India (CJI) was full and effective
Indian Polity, M. Laxmikanth, Chapter 26, p. 285. Although this specific interpretation of appointments was later overturned by the Second and Third Judges cases, the liberalization of
locus standi established in
S.P. Gupta remains the bedrock of PIL in India today.
| Feature | Traditional Locus Standi | Post-S.P. Gupta (PIL) |
|---|
| Who can sue? | Only the victim/aggrieved person. | Any public-spirited citizen/group. |
| Primary Objective | Enforcement of individual rights. | Enforcement of public duties and social justice. |
| Judicial Role | Passive arbiter. | Active protector of the marginalized. |

8. Solving the Original PYQ (exam-level)
Now that you have mastered the evolution of the Indian judiciary, you can see how the concept of Judicial Activism directly translates into procedural changes. This question tests your ability to identify the specific legal turning point where the court moved from a restrictive, colonial-era interpretation of standing to a more inclusive, pro-people approach. The building blocks of Public Interest Litigation (PIL) and Social Justice that you just learned come together here: for the court to protect the rights of the marginalized, it first had to lower the entry barrier known as Locus Standi (the right to be heard).
To arrive at the correct answer, (C) S.P. Gupta v. Union of India, look for the case that provided the formal legal theory behind this shift. Often referred to as the First Judges' Case (1981), it was here that Justice P.N. Bhagwati articulated that any public-spirited citizen or social group could approach the court on behalf of those who, by reason of poverty or disability, cannot access justice themselves. As detailed in Indian Polity, M. Laxmikanth, while earlier cases like Hussainara Khatoon initiated the PIL era, it was S.P. Gupta that established the comprehensive jurisprudential foundation for liberalizing standing.
A common UPSC trap is to select "famous" cases that involve different constitutional principles. Kesavananda Bharati and Minerva Mills are legendary, but they focus on the Basic Structure doctrine and the balance between Fundamental Rights and Directive Principles, not the procedural rules of filing a petition. Similarly, S.R. Bommai is the definitive authority on Article 356 (President's Rule) and secularism. In the exam, always distinguish between substantive cases that change the law's content and procedural cases, like S.P. Gupta, that change who can enter the courtroom.
