 Environmental Policies in India: Landmark Case Laws and Judicial Activism (Part III)

 Author: Chandan Sha


Introduction

While laws and policies form the foundation of environmental governance, the Indian Judiciary has played a major role in filling the gaps where legislation was silent or enforcement was weak. Through Public Interest Litigations (PILs) and progressive interpretations of constitutional provisions, Indian courts have shaped the course of environmental protection in the country. In this final part of the series, we highlight key case laws that transformed India’s environmental policies and ensured accountability.


 Role of the Judiciary in Environmental Protection

Indian courts have relied heavily on:

  • Article 21 (Right to Life)
  • Article 48-A (Protection of Environment – DPSP)
  • Article 51-A(g) (Fundamental Duty to protect environment)

Environmental issues have been treated as part of the Right to Life, expanding the meaning of a dignified life to include clean air, water, and a healthy ecosystem.


 Key Landmark Judgments

1. Rural Litigation and Entitlement Kendra v. State of Uttar Pradesh (1985)

Facts: The case involved illegal limestone mining in the Mussoorie hills which caused deforestation and water pollution.

Held: The Supreme Court ordered the closure of mines to protect the environment. It introduced the principle of sustainable development and stated that economic interests must not override environmental protection.

2. M.C. Mehta v. Union of India (Oleum Gas Leak Case) (1987)

Facts: Oleum gas leaked from a fertilizer plant in Delhi, causing harm to people and the environment.

Held: The SC evolved the ‘Absolute Liability’ principle. If an industry is engaged in a hazardous activity, it is completely liable for any damage, without exceptions.

3. M.C. Mehta v. Union of India (Ganga Pollution Case) (1988)

Facts: Several industries were polluting the Ganga river.

Held: The court directed industries to install effluent treatment plants (ETPs) and shut down non-compliant units. This case pushed stricter environmental monitoring by pollution control boards.

4. Indian Council for Enviro-Legal Action v. Union of India (1996)

Facts: Illegal chemical industries caused groundwater pollution in a village in Rajasthan.

Held: The SC ordered closure and clean-up and applied the Polluter Pays Principle. This landmark case emphasized that polluters must bear the cost of environmental damage.

5. Vellore Citizens’ Welfare Forum v. Union of India (1996)

Facts: Leather industries in Tamil Nadu discharged toxic waste into water bodies.

Held: Introduced the Precautionary Principle and reiterated Polluter Pays Principle. Directed industries to set up treatment plants and compensate for damage.

6. A.P. Pollution Control Board v. Prof. M.V. Nayudu (1999)

Held: Emphasized the need for scientific expertise in environmental cases. Recognized that precaution is better than cure when scientific uncertainty exists. Courts must act cautiously when environmental damage is possible.

7. T.N. Godavarman Thirumulpad v. Union of India (Ongoing since

Facts: PIL on illegal deforestation and misuse of forest land.

Held: SC redefined the term “forest” and placed all forest lands under protection, even if not officially recorded as forests. This case led to the expansion of forest conservation measures and checks on illegal mining and deforestation.

8. Subhash Kumar v. State of Bihar (1991)

Citation: AIR 1991 SC 420

Held: Recognized the right to clean water and air as a fundamental right under Article 21. Strengthened the idea that environmental quality directly affects the quality of life.

9. Municipal Council, Ratlam v. Vardhichand (1980)

Citation: AIR 1980 SC 1622

Held: Municipal authorities were ordered to clean open drains and prevent environmental harm. The case reinforced the duty of public authorities to maintain public hygiene and sanitation.


 Principles Evolved Through Case Laws

These judgments established several important doctrines:

Legal Principle Explanation
Absolute Liability No exceptions for hazardous industries—complete liability for damage.
Polluter Pays Principle Polluters must pay for restoration and compensation.
Precautionary Principle Act before damage occurs—don't wait for proof.
Sustainable Development Balance between development and environmental protection.
Intergenerational Equity Preserve environment for future generations.
Public Trust Doctrine Natural resources are held by the government in trust for the people.


 Impact on Environmental Policy

Thanks to these judgments:

  • Environmental clearance procedures became stricter.
  • Pollution control laws were more effectively enforced.
  • Environmental education was introduced in school curricula.
  • The National Green Tribunal (NGT) was established in 2010 to speed up environmental justice.
  • The government now conducts Environmental Impact Assessments (EIA) before approving major projects.
  • The judiciary ensured accountability of industries and public bodies in environmental matters.


 Conclusion

India's environmental journey is not just shaped by policies and plans, but also by a proactive judiciary. These landmark judgments gave real meaning to the right to life under Article 21 by protecting the environment as an essential part of human existence. Courts have not only interpreted the law—they’ve filled policy gaps, enforced accountability, and laid down foundational principles for a greener India.

As citizens, understanding these legal milestones is key to becoming active protectors of our environment.

“ Law in My Mind, Justice in My Hand” In Labour Law, I see the fight, For equal pay and worker’s right. No child at work, no unjust strain, The law steps in to stop the pain. The Constitution, bold and grand, Gives rights to all across the land. From speech to vote, from faith to life, It calms the storms, it ends the strife. Environment Law, a growing plea, To save the sky, the land, the sea. No trees to cut, no waste to spill, Protect the Earth—we always will. A student now, I read and write, To stand for truth, to stand for right. In every case and every clause, I walk the path of noble laws.

Public Trust Doctrine: Protecting Natural Resources for All Author: Chandan Sha  Introduction The Public Trust Doctrine is a legal principle that says certain natural resources like air, water, forests, and seas are so important to all of us that the government must protect them for the benefit of the public. These resources are not owned by anyone privately but are held by the State in trust for future generations . This principle ensures that natural resources are not over-exploited or sold off for private profits at the cost of public interest. Origin of the Doctrine The doctrine started in Roman law , where it was said that things like air, sea, and running water are common to all mankind. It was further developed in English common law and adopted in many countries, including India. In India, the doctrine became a part of environmental jurisprudence through a landmark judgment by the Supreme Court in the 1990s. Article 48A added to Constitution of India through ...
