• The Central Government's Enforcement Powers
A. Environment (Protection)Act,1986—Sections3and5
The Environment (Protection) Act,1986(EPA) forms the backbone of environmental governance for India. It is built around two working pillars:
1. Section3— Power to Take Measures:
2. Confers on the Central Government the power to take "all such measures as it deems necessary or expedient" for protecting and improving environmental quality and for preventing, controlling, and abating environmental pollution.
3. Section3(2)enumeratesillustrativemeasuresincludingcoordinationwithStateauthorities, laying down standards, planning nationwide programmes, and establishing environmental laboratories.
4. Thisisthepolicy-and-power-conferralprovision—itestablishestheconstitutionaland statutory basis for executive environmental action.
5. Section5— Power to Issue Binding Directions:
6. Authorises the Central Government to issue written directions to any person, officer ,or authority.
7. TheexplanationtoSection5clarifiesthat "directions" includes the power to close ,prohibit ,or regulate any industry, operation, or process, and to stop or regulate the supply of electricity, water, or other services.
8. This is the coercive enforcement provision — it gives the Centre teeth to compel compliance.
9. Section5Aprovides for an appeal to the National Green Tribunal against directions issued under Section 5_Act_1986
10. JudicialInterpretationofSections3 and5:
11. Courts have consistently upheld abroad, purposive reading of the EP Aasawelfarestatute, read in conjunction with constitutional duties under Articles 48A and 51A(g).
12. At the same time, judicial review requires that Section 5 directions be exercised in conformitywithnaturaljusticeandstatutorypurpose,unlessurgencyjustifiesimmediate action.
13. The standard of review focuses on whether the direction is statutorily authorised, proportionate, non-arbitrary, and supported by material—courts do not substitute their own policy judgment for that of the executive.
National Green Tribunal—Jurisdiction and Governing Principles
A. TheNGTAct,2010—Sections14,19,and20
The National Green Tribunal Act, 2010(Act No.19of2010) was enacted to provide for the effective and expeditious disposal of cases relating to environmental protection and
Conservation off orestsandother natural resources ,including enforcement of legal rights relating to the environment and granting relief and compensation for damages.
The Preamble expressly references India's obligations under the Stockholm Conference (1972) and the Rio de Janeiro Conference (1992),and recognizes that the right to a healthy environment has been construed as part of the right to life under Article 21.
1. Section14— Original Civil Jurisdiction:
2. 2. The NGT has original civil jurisdiction over disputes involving a substantial question relating to the environment arising from the enactments listed in Schedule I LL.
3. Section 2(m) defines "substantial question relating to environment" to include direct violation of a specific statutory environmental obligation causing broad public impact, substantial environmental or property damage, or measurable public health harm, and the issue must relate to a specific activity or point source of pollution.
4. The jurisdictional fact forSection14 is the existence of such a substantial question—the dispute must be civil in nature and must arise from a Schedule I enactment.
5. Section19—Procedure:
6. The NGT is guided by principles of natural justice and is not strictly bound by the Code of Civil Procedure or the Indian Evidence Act; it may regulate its own procedure.
7. Section20— Governing Principles:
8. In deciding disputes, the NGT must apply the principles of sustainable development, the precautionary principle, and the polluter pays principle .
9. The Supreme Court has upheld the constitutional validity of the NGT's jurisdictional framework, including Sections 14and22,andhasrecognisedtheNGTasaspecialized environmental adjudicatory body.
Foundational Doctrines of Indian Environmental Jurisprudence
A. Vellore Citizens' Welfare Forum v. Union of India—Precautionary Principle and Polluter Pays Principle
Ratio Decidendi :
1. Precautionary Principle: The Supreme Court held that where there is at hreat of serious or irreversible environmental harm, lack of full scientific certainty cannot be used to delay preventive action. State authorities must anticipate, prevent, and attack the causes of environmental degradation
2. Polluter Pays Principle: The polluter must bear the cost of pollution control, remediation, and compensation; the financial burden cannot be shifted to the public. Polluting industries bear strict liability to compensate for environmental damage and restore affected ecosystems.
3. SustainableDevelopment:Environmentalprotectionandeconomicdevelopment must be balanced; development cannot proceed at the cost of ecological destruction.
4. Strict Liability for Remediation: Polluting industries bear strict liability to compensate for environmental damage and restore affected ecosystems; industries cannot operate without functional effluent treatment facilities. Note: 'absolute liability' as a distinct doctrine (with no exceptions) was established in M.C. Mehta (Oleum Gas Leak), not in Vellore.
Significance and Subsequent Application:
The Vellore principles have been cited consistently across courts to reinforce state liability, environmental accountability, and the application of Section 20 of the NGT Act. The precedent has been applied by: - The Supreme Court - The Madras High Court the High Court of Andhra Pradesh- the High Court of Karnataka-The High Court of Delhi The case marked a shift from purely reactive pollution control to proactive, principle-based enforcement through constitutional and statutory environmental jurisdiction.
The Court also directed institutional and remedial measures under the EPA, including creation of an authority to monitor compliance.
A.P. Pollution Control Board v. Prof. M.V. Nayudu ((1999) 2 SCC 718) is a co-equal foundational Supreme Court authority reaffirming the precautionary approach and must be read alongside Vellore as part of the bed rock of Indian environmental jurisprudence. Both decisions together establish the precautionary principle as a binding norm in Indian law, and subsequent courts and the NGT have applied them in tandem.
B. M.C.Mehta v. Union of India—Absolute Liability and Constitutional Environmental Enforcement Absolute Liability Principle (Oleum Gas Leak):
1. The Supreme Court laid down the principle of absolute liability for enterprises engaged in hazardous or inherently dangerous activities.
2. Such enterprise so we a non-delegable duty to ensure no harm results from their operations; if harm occurs, liability is absolute — subject to no exceptions recognized under Rylands v. Fletcher.
3. Compensation is tied to the enterprise's magnitude and capacity, reflecting the Court's focus on effective deterrence and victim compensation.
4. This was a major departure from the older strict liability model, creating a rule better suited to industrial accidents with widespread public harm.
Constitutional Environmental Enforcement:
1. In matters involving large-scale fundamental rights violations, the Court maintains a constitutionaldutytointerveneurgently—particularlywhenstateimplementersabetthese violations — to preserve the rule of law.
2. In the in dustrial re location line of M.C. Mehta cases, hazardous and heavy industries in Delhi were ordered to vacate premises; the Supreme Court clarified that industries must voluntarily surrender the vacated land to the Delhi Development Authority (DDA) rather than requiring DDA acquisition under Section 15 of the Delhi Development Act, and noncompliance permits the DDA to file execution applications directly before the District Judge, Delhi.
3. UnderSections3, 4, and5ofthePunjabLandPreservationAct, 1900, state notifications restricting specific land uses in environmental zones such as the Aravalli Range remain enforceable.
Significance: The case demonstrates the Supreme Court's willingness to expand fundamental rights-based environmental protection, impose stricter responsibility on hazardous industries, and use constitutional remedies under Article 32 to enforce environmental safety.
JudicialandEnforcementTrends:2025–2026
1. Stricter Accountability with Case-Specific Balancing:
2. The strongest judicial trend in 2025–2026 is toward stricter accountability, but with casespecificbalancingwhereclean-energyorpublic-interestconsiderationsareinvolved.
3. Courts are not relaxing environmental law generally; instead, enforcement is becoming more targeted and evidence-based .
4. Corporate Environmental Responsibility Linked to CSR:
5. In the Great Indian Bustard line of cases ,the Supreme Court noted that CSR cannot be divorced from Corporate Environmental Responsibility, and approved expert recommendations aimed at protecting the critically endangered species while allowing India's renewable-energy transition to proceed in a regulated manner.
6. Balanced Enforcement Model—Expert-Driven Adjudication:
7. The Court is using a balanced enforcement model instead of only blanket bans. In the Diwali green-crackers matter, the Supreme Court allowed limited sale and use of NEERI approved green cracker sin NCR for a specified period as a temporary test case ,while insisting on strict time limits and regulatory compliance
8. There is a visible shift toward expert-driven adjudication in technically complex disputes, especially where environmental protection intersects with energy transition, industry, or public necessity.
9. Polluter Pay sand Environmental Compensation Remain Central:
10. Environmental compensation and accountability remain central to Tribunal reasoning. A 2025 NGT decision held that a Rajasthan State Pollution Control Board notification exempting "back period" environmental compensation was invalid ,rein forcing the principle that industries must remain liable for environmental harm and compliance failures
11. Polluter-pays principles and compensation mechanisms continue to be treated as important enforcement tools, especially in NGT practice.
12. Zero Tolerance for Post-Facto Clearances:
13. Vanashakti v. Union of India (2025) confirms that the Supreme Court's zero-tolerance approach to ex post facto EC remains intact and is being actively applied to invalid at regulatory instruments that permit such clearances.
14. Continuing Oversight and Proactive NGT Role:
15. Following Municipal Corporation of Greater Mumbai v. Ankita Sinha ,the NGT's suo motu and proactive enforcement role continues to be affirmed, with the Tribunal acting on credible inputs including media reports and letter petitions.
