4. Writ Jurisdiction and Environmental Protection | Articles 32 and 226, Public Interest Litigation and Continuing Mandamus

This is the 4th post in Environmental Law, Unit IV — the previous post covered legislative competence; this post covers how affected people, and often concerned strangers, actually get environmental disputes in front of a court in the first place.

The Problem This Topic Solves

Environmental harm rarely has a single, easily identifiable victim who can afford the years an ordinary civil suit takes, or who even has the legal standing to sue under the traditional rule that only a person directly and personally injured may approach a court. A river poisoned by industrial effluent injures an entire riparian population, most of whom are poor, unorganised and in no position to litigate; a forest cleared illegally harms a diffuse public interest in conservation that no single person "owns." Ordinary remedies were never designed for this kind of harm. The writ jurisdiction of the Supreme Court and the High Courts, combined with a deliberately relaxed approach to who may bring a case, became the practical route through which Indian environmental law actually gets enforced.

Article 32 — the Supreme Court's Writ Jurisdiction

Article 32 gives every person the right to move the Supreme Court directly for the enforcement of the Fundamental Rights guaranteed by Part III of the Constitution, and empowers the Supreme Court to issue directions, orders or writs — including writs in the nature of habeas corpus, mandamus, prohibition, quo warranto and certiorari — for that purpose. Article 32 is itself listed as a Fundamental Right (Dr. B.R. Ambedkar famously called it "the heart and soul of the Constitution"), which means the right to approach the Supreme Court for enforcement cannot itself be taken away by ordinary legislation. Because it is tied to Part III, an Article 32 petition must be framed around a Fundamental Right — in the environmental context, almost always Article 21's right to life, read to include a right to a healthy environment.

Article 226 — the High Courts' Wider Writ Jurisdiction

Article 226 gives every High Court power, within its territorial jurisdiction, to issue the same kinds of writs — but for two purposes, not one: for the enforcement of Fundamental Rights, exactly as under Article 32, and also "for any other purpose," meaning the enforcement of ordinary legal rights created by statute even where no Fundamental Right is at stake. This makes Article 226 wider in subject-matter than Article 32, even though it is narrower in one sense — a High Court's writ jurisdiction is confined to its own territorial limits, while the Supreme Court's Article 32 jurisdiction runs across all of India. In practice, most environmental litigation actually begins in a High Court under Article 226, since it covers both constitutional and ordinary statutory violations (such as a Pollution Control Board's failure to act under the Water Act or Air Act), with appeal or a fresh Article 32 petition to the Supreme Court reserved for matters of wider or unresolved constitutional importance.

Public Interest Litigation — Relaxing Who May Approach the Court

The traditional rule of locus standi required a petitioner to show direct, personal injury before a court would even hear the case — a rule that made no sense for pollution affecting thousands of poor, unorganised people who could never individually litigate. Starting in the late 1970s and through the 1980s, the Supreme Court progressively relaxed this rule, holding that any member of the public acting bona fide, and not for a private or political motive, may approach the court on behalf of a class of persons whose own legal rights have been violated but who are, by reason of poverty, disability or socially or economically disadvantaged position, unable to approach the court themselves. Courts even began treating a simple letter addressed to a judge, describing an environmental or human-rights violation, as a writ petition in itself — a practice known as epistolary jurisdiction. This relaxed standing is precisely how M.C. Mehta, an environmental lawyer with no personal stake in the Ganga's pollution, could bring the Ganga Pollution case, and how the Rural Litigation and Entitlement Kendra, an organisation rather than an injured individual, could challenge illegal limestone quarrying in the Mussoorie hills.

Continuing Mandamus — an Environment-Specific Innovation

An ordinary writ of mandamus is a one-time command — the court directs an authority to perform a specific duty, and the case ends once that direction is carried out. Environmental degradation is rarely a one-time problem: forest protection, river cleaning or air-quality management require sustained, monitored action over years or decades, which a single order cannot secure. To address this, the judiciary developed the technique of continuing mandamus — keeping a writ petition formally open indefinitely, issuing a long sequence of successive orders, calling for periodic compliance reports from the government and expert committees, and effectively supervising the executive's implementation of environmental policy over an extended period, rather than disposing of the case after one final order. This technique is covered in this site's Glossary in full, with T.N. Godavarman Thirumulpad v. Union of India (this subject's Unit III Case-Law list) as its leading illustration.

• Article 32 lets a person move the Supreme Court directly for enforcement of a Fundamental Right (in environmental cases, almost always Article 21); it is itself a Fundamental Right.
• Article 226 gives every High Court writ power within its territory for enforcement of Fundamental Rights AND "for any other purpose" — wider in subject-matter than Article 32, though territorially limited.
• Public Interest Litigation relaxed the traditional locus standi rule, letting a bona fide member of the public (even an individual lawyer or an NGO with no personal injury) approach the court on behalf of an affected but disadvantaged class — the route through which almost all major environmental cases have reached the courts.

• Epistolary jurisdiction — treating a letter to a judge as a formal writ petition — was itself a product of the same standing-relaxation movement that produced PIL, and both developed together through the same line of 1980s cases.
• Continuing mandamus is not a separate constitutional provision — it is a judicially-invented technique for exercising the ordinary mandamus power under Articles 32/226 over an extended timeframe, first used at scale in environmental litigation.
• Since 2010, many environmental disputes that would earlier have gone straight to a writ court can instead go to the National Green Tribunal, a specialised statutory tribunal — writ jurisdiction remains available, but is no longer the only route.

A Related but Separate Body — the National Green Tribunal

The National Green Tribunal Act, 2010 created a dedicated statutory forum for environmental disputes, meant to offer faster, more technically-equipped adjudication than a writ court. How the NGT's own jurisdiction works, and how it interacts with the writ jurisdiction covered in this post, is a distinct statutory topic covered in this subject's Unit III.

A Practical Example

Suppose residents of a slum colony downstream of a dyeing factory are falling ill from contaminated groundwater, but are daily-wage workers who cannot afford a lawyer or the years an ordinary civil suit would take. A local journalist who has reported on their condition writes a plain letter to the Chief Justice of the relevant High Court describing the situation. Under the epistolary-jurisdiction practice built out of relaxed locus standi, the High Court can register that letter itself as a writ petition under Article 226, appoint a fact-finding committee, and — if it finds the harm ongoing rather than a single past event — keep the matter open under a continuing mandamus, directing the Pollution Control Board and factory to report back periodically until compliance is achieved, rather than closing the case after one order.

Quick Revision Points

• Article 32: Supreme Court, Fundamental Rights only, itself a Fundamental Right.
• Article 226: High Courts, Fundamental Rights + any other legal right, territorially limited.
• PIL: relaxed locus standi lets a bona fide public-spirited person/NGO sue on behalf of a disadvantaged affected class.
• Epistolary jurisdiction: a letter to a judge can itself be treated as a writ petition.
• Continuing mandamus: keeps a writ petition open with successive orders for long-term monitoring — pioneered in cases like T.N. Godavarman.
