Environment Laws
The Character of Environmental Law: Environmental Law as Public Law, as Regulatory Law and as Human Rights Law
Environmental law can be studied through three lenses. As public law it governs the relationship between the State and the individual, with the State acting as regulator and trustee. As regulatory law it controls conduct in advance, through standards, licences, inspection and sanctions administered by expert agencies. As human rights law it protects the individual's claim to a healthy environment against the State and others. Each lens explains a different part of the subject, and the strongest answers use all three.
1. From Private Law to Public Law
Environmental protection began in private law. A landowner whose crops were damaged by fumes, or whose well was fouled, could sue in nuisance, negligence or trespass, or under the rule in Rylands v. Fletcher (1868). These remedies still exist, but they were designed for disputes between neighbours and prove inadequate against modern, diffuse pollution.
1.1 Limitations of private law remedies
Limitation | Explanation |
|---|---|
Standing | Only a person whose own right is affected can sue. The environment itself, and the public at large, have no voice |
Causation | The plaintiff must prove that this defendant caused this harm, which is nearly impossible where many sources contribute |
Remedy | Damages come after the harm and rarely restore the environment; injunctions are discretionary |
Cost and delay | Civil litigation is expensive and slow, and the parties are unequal in resources |
Individual focus | Private law protects property and person, not ecological values or future generations |
Public law overcomes these limits. It acts through the State, it protects public interests, it permits anyone with a bona fide concern to approach the court, and it operates before as well as after harm.
2. Environmental Law as Public Law
Public law is the branch of law that regulates the structure and powers of the State and its relationship with individuals. Environmental law is predominantly public law, for five reasons.
- The State is the principal actor. It legislates, sets standards, grants consents, monitors and enforces. Article 48A places the duty to protect and improve the environment on the State.
- The State is trustee of natural resources. Under the public trust doctrine (M.C. Mehta v. Kamal Nath, 1997) the State holds rivers, forests, seashores and air in trust for the public.
- Public remedies dominate. Writs under Articles 32 and 226, public interest litigation and proceedings before the National Green Tribunal are the main avenues of redress.
- Standing is relaxed. Following S.P. Gupta v. Union of India, 1981 Supp SCC 87, any public-spirited person may approach the court on behalf of the public or the environment.
- Public interest prevails over private interest. Trade and property rights yield to environmental requirements, as reasonable restrictions under Article 19(6) and as limits on the use of property.
2.1 Public law remedies in environmental cases
Remedy | Provision | Use in environmental matters |
|---|---|---|
Writ petition, including public interest litigation | Articles 32 and 226 | The vehicle for almost every landmark environmental judgment |
Conditional order for removal of public nuisance | Section 152, BNSS (formerly Section 133, CrPC) | Summary remedy before the Magistrate (Municipal Council, Ratlam v. Vardhichand, 1980) |
Suit for public nuisance | Section 91, Code of Civil Procedure, 1908 | By the Advocate General, or by two or more persons with leave of the court, without proof of special damage |
Application to the National Green Tribunal | Sections 14 to 16, NGT Act, 2010 | Original jurisdiction over substantial environmental questions; appeals; relief and compensation |
Citizen complaint | Section 19(b), EPA; Section 49, Water Act; Section 43, Air Act | Any person may complain after sixty days' notice to the authority |
2.2 The hybrid character
Environmental law is predominantly public, but not purely so. Private law remedies continue to operate, and courts sometimes combine the two. The Kamal Nath litigation illustrates the interaction.
📖 M.C. Mehta v. Kamal Nath, (2000) 6 SCC 213 and (2002) 3 SCC 653 Facts: After finding that a motel company had interfered with the course of the river Beas, the Court considered whether it could impose a 'pollution fine' in addition to requiring restitution. Held: A pollution fine, being a penalty, could not be imposed under Article 32 without a trial and adjudication under the relevant statute. But the company could be required to pay exemplary damages under the law of torts, as a deterrent. In 2002 the Court quantified exemplary damages. Ratio: Public law courts may draw on private law remedies such as exemplary damages, but penal consequences must follow the procedure prescribed by statute. |
✦ Coaching analogy: referee and neighbour Private law is a quarrel between two neighbours over a hedge. Public law puts a referee on the field who blows the whistle for everyone. Environmental law needs a referee because the players are many, the field belongs to all, and some of the injured (future generations, wildlife) cannot play at all. |
3. Environmental Law as Regulatory Law
Regulatory law is law that controls conduct in advance, through rules administered by specialised agencies. It does not wait for harm; it sets conditions on which an activity may be carried on, watches whether they are met, and intervenes when they are not. Most of Indian environmental law takes this form.
3.1 Features of environmental law as regulatory law
Feature | How it appears in Indian environmental law |
|---|---|
Delegated legislation | Standards and procedures are fixed by rules and notifications under the EPA, the Water Act and the Air Act rather than in the Acts themselves |
Expert agencies | The Central and State Pollution Control Boards, the Expert Appraisal Committees, the Commission for Air Quality Management |
Licensing | Consent to establish and consent to operate (Sections 25 and 26, Water Act; Section 21, Air Act); prior environmental clearance (EIA Notification, 2006); forest clearance |
Standards | Emission, discharge and ambient standards (Sections 3 and 7, EPA) |
Monitoring and inspection | Powers of entry and inspection (Section 10, EPA) and of taking samples (Section 11, EPA); environmental statements (Rule 14, Environment (Protection) Rules) |
Enforcement | Directions for closure, prohibition or regulation, including stoppage of electricity and water (Section 5, EPA; Section 33A, Water Act; Section 31A, Air Act); applications to courts to restrain pollution (Section 33, Water Act; Section 22A, Air Act) |
Sanctions | Monetary penalties imposed by adjudicating officers after the 2023 and 2024 amendments; environmental compensation |
3.2 Models of regulation
Model | Method | Indian example | Strength and weakness |
|---|---|---|---|
Command and control | Fixed standards backed by sanctions | Emission standards; consents | Certain and enforceable, but rigid and dependent on inspection capacity |
Market-based | Prices and tradable rights create incentives | Carbon credit trading; extended producer responsibility; environmental compensation | Efficient, but may let wealthy polluters pay to pollute |
Information-based | Disclosure and public scrutiny | Environmental statements; EIA public hearing; eco-labelling | Cheap and democratic, but depends on an active public |
Self and co-regulation | Industry monitors itself under oversight | Online continuous emission monitoring; environmental audit | Reduces the regulator's burden, but risks self-serving compliance |
3.3 The centrality of prior clearance
The heart of preventive regulation is that permission comes before the activity. Whether a clearance can be granted after a project has begun has been one of the most contested regulatory questions of recent years.
📖 Alembic Pharmaceuticals Ltd. v. Rohit Prajapati, (2020) 17 SCC 157 Facts: Industrial units in Gujarat had been granted environmental clearance after they had commenced operations, on the strength of a 2002 administrative circular. Held: The concept of an ex post facto environmental clearance is contrary to the fundamental principles of environmental jurisprudence and is an anathema to the EIA Notification. The circular was contrary to the notification. Instead of closing the units, the Court imposed environmental compensation. Ratio: Prior clearance is the foundation of the regulatory scheme; a circular cannot dilute a statutory notification. |
📖 The Vanashakti litigation (2025 to 2026) Facts: A 2017 notification and a 2021 office memorandum of the Ministry allowed projects that had started without prior environmental clearance to obtain clearance later on payment of penalties. Held: In May 2025 a two-judge bench struck down both instruments as contrary to the EIA Notification and to Alembic. On review, a three-judge bench by a 2:1 majority recalled that judgment in November 2025 and directed a fresh hearing; Justice Bhuyan dissented. On the fresh hearing, on 29 July 2026 a bench led by Chief Justice Surya Kant upheld the 2017 notification as a narrowly tailored, time-bound amnesty made by statutory notification under Section 3 of the EPA, but quashed the 2021 office memorandum prospectively as ultra vires, holding that post-facto clearance can be provided only by statutory notification and not by administrative orders. Clearances already granted remain valid unless individually challenged. Ratio: A regulatory lesson: executive relaxation of a statutory safeguard must itself take statutory form and be narrowly tailored. Prior clearance remains the rule. |
📖 Common Cause v. Union of India, (2017) 9 SCC 499 Held: Mining leases in Odisha operated in excess of the quantity permitted by the environmental clearance, or without clearance, were illegal. The lessees were directed to pay compensation equal to the price of the ore illegally extracted. Ratio: Operating outside the terms of a clearance is operating without one; regulatory limits are enforceable through full restitution of illegal gains. |
3.4 Weaknesses of the regulatory model
- Capacity. Pollution control boards are frequently short of technical staff, laboratories and funds.
- Independence and expertise. In Techi Tagi Tara v. Rajendra Singh Bhandari, (2018) 11 SCC 734, the Supreme Court expressed concern at the appointment of persons without relevant expertise to head State Pollution Control Boards and directed that appointment rules be framed.
- Regulatory capture. Close contact between regulator and regulated industry can soften enforcement.
- Dilution through executive instruments. Office memoranda and circulars have sometimes relaxed statutory requirements, as Alembic shows.
4. Environmental Law as Human Rights Law
The human rights lens asks what the individual is entitled to. Environmental human rights are of two kinds: substantive rights to a certain quality of environment, and procedural rights that allow people to take part in environmental decisions.
4.1 Substantive environmental rights in India
Right | Leading authority |
|---|---|
Right to a pollution-free environment as part of the right to life | Subhash Kumar v. State of Bihar, (1991) 1 SCC 598; Virender Gaur v. State of Haryana, (1995) 2 SCC 577 |
Right to clean drinking water | A.P. Pollution Control Board II v. Prof. M.V. Nayudu, (2001) 2 SCC 62; Narmada Bachao Andolan v. Union of India, (2000) 10 SCC 664 |
Right to health of workers exposed to hazards | Consumer Education and Research Centre v. Union of India, (1995) 3 SCC 42 (asbestos industry) |
Right to freedom from noise and to sleep | Noise Pollution (V), In re, (2005) 5 SCC 733 |
Right to be free from the adverse effects of climate change | M.K. Ranjitsinh v. Union of India, 2024 INSC 280 |
Rights of forest-dwelling communities, including religious and cultural rights | Orissa Mining Corporation v. Ministry of Environment and Forests, (2013) 6 SCC 476 |
4.2 Procedural environmental rights
Principle 10, Rio Declaration, 1992 — the three access rights Environmental issues are best handled with the participation of all concerned citizens, at the relevant level. At the national level, each individual shall have appropriate access to information concerning the environment that is held by public authorities, and the opportunity to participate in decision-making processes. States shall facilitate and encourage public awareness and participation by making information widely available. Effective access to judicial and administrative proceedings, including redress and remedy, shall be provided. |
Access right | Indian mechanism |
|---|---|
Information | Right to Information Act, 2005; publication of EIA reports; environmental statements |
Participation | Public consultation and public hearing under the EIA Notification, 2006; Gram Sabha consent under the Forest Rights Act, 2006 |
Justice | Public interest litigation under Articles 32 and 226; the National Green Tribunal; citizen complaints under Section 19, EPA |
Principle 10 was given binding form regionally by the Aarhus Convention, 1998 (Europe) and the Escazú Agreement, 2018 (Latin America and the Caribbean). India is party to neither, but its domestic law secures all three access rights.
4.3 International recognition
Year | Development |
|---|---|
1972 | Stockholm Declaration, Principle 1: the fundamental right to an environment of a quality that permits a life of dignity and well-being |
2017 | Inter-American Court of Human Rights, Advisory Opinion OC-23/17: the right to a healthy environment is an autonomous right |
2021 | UN Human Rights Council Resolution 48/13 recognises the right to a clean, healthy and sustainable environment |
2022 | UN General Assembly Resolution 76/300 recognises the same right as a human right |
2024 | Verein KlimaSeniorinnen Schweiz v. Switzerland (European Court of Human Rights, Grand Chamber): Article 8 of the European Convention includes a right to effective protection by the State from the serious adverse effects of climate change |
2025 | International Court of Justice, Advisory Opinion on the Obligations of States in respect of Climate Change (23 July 2025): a clean, healthy and sustainable environment is a precondition for the enjoyment of many human rights |
📖 A.P. Pollution Control Board II v. Prof. M.V. Nayudu, (2001) 2 SCC 62 Facts: The sequel to the 1999 decision on a hazardous industry near the reservoirs supplying drinking water to Hyderabad. Held: The right to access to drinking water is fundamental to life, and there is a duty on the State under Article 21 to provide clean drinking water. The State's exemption permitting the industry was set aside. Ratio: Environmental protection of drinking water sources is a constitutional duty, enforceable as a human right. |
📖 Verein KlimaSeniorinnen Schweiz v. Switzerland (ECtHR, Grand Chamber, 9 April 2024) Facts: An association of older Swiss women complained that Switzerland's inadequate climate policy exposed them to heat-related harm. Held: Article 8 of the European Convention on Human Rights encompasses a right to effective protection by the State from the serious adverse effects of climate change. Switzerland had failed to put in place an adequate regulatory framework, and had violated Article 8. Ratio: The first ruling of an international human rights court that a State's climate inaction violates human rights. Useful as a comparative authority alongside Ranjitsinh. |
4.4 Limits of the human rights approach
- Anthropocentrism. Rights belong to humans; the approach protects nature only for human benefit.
- Conflict of rights. The right to a clean environment may collide with the right to livelihood, as when polluting industries employing thousands are closed or relocated.
- Vagueness. 'Clean' and 'healthy' are not self-defining; courts must still rely on standards set by regulators.
- Enforcement. A declared right is only as strong as the institutions that enforce it.
⚠ Balancing environment and livelihood When the Supreme Court ordered the relocation of hazardous and polluting industries from residential areas of Delhi in the 1990s, it also directed that affected workers receive compensation and continuity of employment. Examiners reward answers that recognise this tension and show how courts have tried to reconcile the two rights, rather than treating the environment as always prevailing. |
5. The Three Lenses Compared
Public law | Regulatory law | Human rights law | |
|---|---|---|---|
Central question | What is the State's power and duty? | How is conduct controlled in advance? | What is the individual entitled to? |
Key actor | The State as sovereign and trustee | Specialised agencies | The individual or community |
Main tool | Writs, PIL, public trust | Standards, consents, inspection, penalties | Fundamental rights; access rights |
Time of intervention | Before or after harm | Before harm | Usually after a threat or violation |
Leading Indian authority | Ratlam; Kamal Nath | Alembic; Sections 3, 5 and 7, EPA | Subhash Kumar; Ranjitsinh |
✦ Mnemonic: 'P-R-H: Power, Rules, Rights' Public law is about the State's Power and duty. Regulatory law is about Rules made and enforced in advance. Human rights law is about the individual's Rights. One subject, three angles. |
