Role of the Judiciary — Writ Jurisdiction and Judicial Activism — Environmental Law Notes

Role of the Judiciary — Writ Jurisdiction and Judicial Activism

When Parliament and the pollution boards were slow, silent or simply overwhelmed, one institution refused to wait — the judiciary. Faced with a poisoned Ganga, a smog-choked Delhi and a discoloured Taj Mahal, the Supreme Court did not merely decide disputes; it governed — ordering industries to relocate, buses to switch to CNG, and effluent plants to be built, then supervising the results for years. Whether you call it activism or rescue, the modern shape of Indian environmental law is largely the judiciary’s handiwork.

How the judiciary protects the environment

The courts had two things Parliament’s statutes often lacked: a broad power to issue orders, and the will to use it. Understanding this topic means understanding both the tool (writ jurisdiction) and the attitude (judicial activism).

A. Writ jurisdiction — the tool

The Constitution arms the courts with a direct power to enforce rights:

1. Article 32 — lets any person move the Supreme Court directly for the enforcement of fundamental rights, by way of writs. Because the right to a healthy environment lives inside Article 21 (Topic 2), the Supreme Court can be approached under Article 32 for environmental harm.
2. Article 226 — gives the High Courts an even wider writ power, both for fundamental rights and for “any other purpose”.

The relevant writs are chiefly mandamus [a command to a public authority to perform its legal duty — for example, ordering a municipality to clean its drains] and, in effect, continuing directions built on that power.

Article 32(1) and Article 226(1): Article 32 guarantees “the right to move the Supreme Court by appropriate proceedings for the enforcement of” the fundamental rights; Article 226 empowers every High Court “to issue to any person or authority … directions, orders or writs … for the enforcement of any of the rights conferred by Part III and for any other purpose.”

In Simple Terms: Article 32 is your direct line to the Supreme Court when a fundamental right — including your right to a clean environment — is violated; Article 226 is the same, and wider, at the High Court. Through these the courts can command a polluter or a lazy authority to act.

B. Judicial activism — the attitude

Judicial activism means the judiciary going beyond a passive, dispute-deciding role to actively protect rights and fill gaps the legislature and executive have left. In environmental cases this has taken concrete forms:

1. Reading new rights into old ones — building the right to a healthy environment into Article 21.
2. Relaxing procedure — creating PIL, epistolary jurisdiction and continuing mandamus (Topic 4).
3. Issuing detailed, continuing directions — the M.C. Mehta line: relocating industries away from the Taj (the Taj Trapezium case, 1997), ordering Delhi’s transport to convert to CNG (1998), and cleaning the Ganga.
4. Evolving the doctrines — the courts invented or imported absolute liability, polluter pays, precaution, public trust and inter-generational equity (Topics 6–11), which had no statutory basis.
5. Appointing expert committees — using scientists and commissions to inform its orders where the judges lacked technical knowledge.

🔑 The mark-scoring frame for this essay: the judiciary acts as the guardian of the environmental right — it supplies what statutes and regulators leave undone, and its most lasting contribution is the set of judge-made doctrines in the next cluster.

The one caution to add for balance: activism has limits. The courts also insist that a petitioner be bona fide, and they recognise that development and environment must be balanced, not that development must always lose — a theme that leads into sustainable development in Unit 3.

🧩 WORKED EXAMPLE — how the judiciary decides an environmental crisis

Facts. Emissions from coal-based industries around a famous marble monument are discolouring it and harming nearby residents; the pollution boards have not acted effectively. A citizen approaches the Supreme Court.

Rule. Under Article 32 the Court can enforce the Article 21 right to a healthy environment; through judicial activism it may issue continuing directions and apply the precautionary principle, placing the onus on industry to prove its operations are safe (the Taj Trapezium approach, M.C. Mehta vs Union of India, 1997).

Apply. The Court can direct the polluting industries either to switch to a clean fuel or to relocate outside the protected zone, and can monitor compliance over time. It need not wait for the boards; the constitutional writ power lets it act directly.

Conclusion. The judiciary steps in where the regulators failed — issuing and supervising directions to save both the monument and the residents’ health. That is judicial activism in environmental protection in action.

Case Laws

• M.C. Mehta vs Union of India (1997) (Taj Trapezium) — to save the Taj Mahal, the Court directed polluting industries in the Taj Trapezium Zone to switch to natural gas or relocate; a leading example of continuing judicial supervision.
• M.C. Mehta vs Union of India (1998) (Vehicular Pollution) — the Court directed Delhi’s public transport to convert to CNG, showing judicial activism against air pollution.
• Indian Council for Enviro-Legal Action vs Union of India (1996) (Sludge case) — the Court fixed responsibility on polluting industries and ordered restoration, acting where regulators had failed.
• Vellore Citizens Welfare Forum vs Union of India (1996) — the Court adopted international principles (precaution, polluter pays, sustainable development) as part of Indian law.
