Public Interest Litigation (PIL): Origin, Scope and Principles

PIL origin scope covers how the Supreme Court, from around 1979, built a new legal mechanism — Public Interest Litigation — that let public-spirited citizens and organisations approach the courts on behalf of people who could not approach the courts themselves, dramatically widening access to justice.

What Is Public Interest Litigation

Public Interest Litigation, or PIL, is legal action taken to enforce a public or general interest in which the public, or a class of persons, has a shared stake, rather than a purely private grievance. It is an exception to the traditional rule of locus standi, under which only a person who was personally aggrieved could move a court. Under PIL, any individual or organisation can approach the Supreme Court or a High Court on behalf of persons whose rights have been violated, even where the petitioner has not personally suffered any injury. The procedure was deliberately simplified: at various points, even a letter addressed to the Supreme Court has been treated by the Court as a PIL petition.

Breaking from Traditional Locus Standi

In the normal course of law, only a person who was personally aggrieved — whose own rights had been violated, or who was a party to a dispute — could move a court. This position changed around 1979, when the Supreme Court decided to hear a case that had not been filed by the aggrieved persons themselves but by others acting on their behalf. Because such cases involved a matter of public interest rather than a purely private dispute, they came to be described as public interest litigations.

Origin: The Hussainara Khatoon Case

One of the earliest and most influential PILs arose from newspaper reports, published in 1979, about undertrial prisoners in Bihar who had spent years in jail awaiting trial — in many cases longer than the sentence they would have received had they actually been convicted of the offences they were arrested for. These reports prompted an advocate to file a petition, which the Supreme Court agreed to hear. The case became known as the Hussainara Khatoon vs. Bihar case and is regarded as one of the earliest Public Interest Litigations in India.

The Sunil Batra Case and the "Letter Petition"

In 1980, a prison inmate at Tihar Jail managed to send a scribbled note to Justice Krishna Iyer of the Supreme Court, describing physical torture of prisoners inside the jail. The judge had this letter converted into a formal petition. Though the Court later moved away from the practice of treating every letter as a petition, this case — known as Sunil Batra vs. Delhi Administration (1980) — became one of the pioneering examples of Public Interest Litigation, illustrating just how far the Court was willing to go, in its early phase, to bring genuine grievances before it despite procedural barriers.

Expanding the Scope of Rights Through PIL

Through PIL, the judiciary substantially expanded the practical meaning of constitutional rights. Interests such as clean air, unpolluted water and decent living conditions came to be treated as rights belonging to society as a whole rather than to any single litigant. PIL and the accompanying rise of judicial activism also made it possible for courts to take up violations affecting sections of society who could not easily approach a court on their own — including cases concerning the abolition of forced labour and the prohibition of hazardous child employment, both covered under the constitutional Right against Exploitation.

PIL as the Vehicle of Judicial Activism

PIL became the most important instrument through which judicial activism has operated in India. The judiciary, traditionally confined to responding only to cases formally brought before it, began entertaining matters on the basis of newspaper reports and postal complaints received directly by the courts. It is this expanded, more proactive role of the judiciary — moving beyond its earlier, passive posture — that came to be popularly described as judicial activism, with PIL as its principal vehicle.

Constitutional Basis: Articles 32 and 226

The constitutional machinery through which PILs are actually litigated is the writ jurisdiction of the courts: Article 32 empowers the Supreme Court, and Article 226 empowers the High Courts, to issue writs such as habeas corpus and mandamus for the enforcement of rights. PIL uses this existing writ jurisdiction, but relaxes the usual requirement that the person moving the court must be the one whose rights were directly violated.

A Comparative Note: South Africa

The practice of public interest litigation has become increasingly accepted well beyond India, particularly in other parts of South Asia and Africa, where courts have adopted forms of judicial activism comparable to India's. South Africa has gone a step further and incorporated public interest litigation directly into its Bill of Rights, making it a fundamental right of citizens to bring before the Constitutional Court cases involving the violation of other persons' rights — a more explicit constitutional guarantee than exists in India, where PIL developed primarily through judicial practice rather than express constitutional text.

FAQ

Q1. What is Public Interest Litigation (PIL)? PIL is legal action to enforce a public or general interest, brought by an individual or organisation on behalf of persons whose rights have been violated, even where the petitioner is not personally aggrieved — an exception to the traditional rule of locus standi.

Q2. When and how did PIL originate in India? PIL emerged around 1979, when the Supreme Court began hearing cases filed by parties other than the aggrieved persons themselves, on matters of public interest; the Hussainara Khatoon case (1979) and the Sunil Batra case (1980) are among its earliest instances.

Q3. Can a letter to the Supreme Court be treated as a PIL? Historically, yes — as in the Sunil Batra case, where a smuggled letter from a Tihar Jail inmate to Justice Krishna Iyer was converted into a formal petition, though the Court later moved away from this practice of accepting every letter.

Q4. Through which constitutional provisions is a PIL actually filed? A PIL is litigated using the writ jurisdiction of the Supreme Court under Article 32 or of a High Court under Article 226, with the standing requirement relaxed to allow public-spirited petitioners.

Q5. How has PIL expanded the scope of rights in India? PIL enabled courts to treat interests such as clean air, unpolluted water and decent living conditions as enforceable rights of society, and to take up violations — such as forced labour and hazardous child employment — affecting people who could not easily approach the courts on their own.
