Passage or principleConstitution of India; Subhash Kumar v. State of Bihar; M.C. Mehta environmental cases

Indian environmental law is not built only on ordinary statutes. Its constitutional foundation lies in the judicial expansion of Article 21, supported by Article 48A and Article 51A(g). Article 21 has been interpreted to include the right to live with human dignity, and environmental degradation has repeatedly been treated as a threat to that dignity. Article 48A directs the State to protect and improve the environment and safeguard forests and wildlife. Article 51A(g) imposes a citizen duty to protect the natural environment and to have compassion for living creatures. In environmental public interest litigation, courts have used these provisions to relax standing, monitor executive compliance, and require pollution control, while also recognising that environmental adjudication must balance health, livelihood, development, and ecological integrity.

Question 1EasyConstitutional Environmentalism

According to the passage, the constitutional basis of environmental protection in India is best described as:

  1. A

    Article 21 read with Article 48A and Article 51A(g).

  2. B

    Article 21 alone, without any relevance of Directive Principles or duties.

  3. C

    Only Article 19(1)(g), because environmental law is a trade issue.

  4. D

    Only Article 300A, because environment is treated as private property.

View answer and explanation

Correct answer: A. Article 21 read with Article 48A and Article 51A(g).

The passage anchors environmental law in Article 21, supported by Article 48A and Article 51A(g).

Question 2MediumConstitutional Environmentalism

Why is flexible locus standi important in environmental PIL?

  1. A

    Because all environmental claims are decided without evidence.

  2. B

View answer and explanation

Correct answer: C. Because environmental harms are often diffuse and affect communities or public resources.

Environmental harm may affect public resources, communities, and future interests, so strict private standing can be inadequate.

Passage or principleVellore Citizens Welfare Forum v. Union of India; Indian Council for Enviro-Legal Action

The Supreme Court in Vellore Citizens Welfare Forum treated sustainable development as part of Indian environmental law and expressly adopted the precautionary principle and polluter pays principle. The precautionary principle changes the posture of environmental governance: where there is a threat of serious or irreversible damage, lack of complete scientific certainty should not be used to postpone preventive action. It also places a burden on the developer or industrial actor to show environmental acceptability in appropriate cases. The polluter pays principle is wider than a penalty. It requires the polluter to bear the cost of compensation and restoration. Indian Council for Enviro-Legal Action applied this reasoning to require polluting industries to pay for remediation of environmental damage.

Question 6MediumEnvironmental Principles

What is the main effect of the precautionary principle in the passage?

  1. A

    It requires preventive action despite scientific uncertainty where serious harm is threatened.

  2. B

    It allows pollution until harm is scientifically certain.

  3. C

    It prohibits every industrial activity without inquiry.

  4. D

    It applies only to private nuisance suits.

View answer and explanation

Correct answer: A. It requires preventive action despite scientific uncertainty where serious harm is threatened.

Precaution prevents scientific uncertainty from becoming an excuse for delay where serious or irreversible harm is possible.

Passage or principleEnvironment (Protection) Act, 1986; Water Act, 1974; Air Act, 1981

India uses a layered pollution control framework. The Water Act, 1974 establishes Central and State Pollution Control Boards and regulates water pollution through consent, sampling, inspection, and enforcement provisions. Section 25 is central to the consent mechanism for outlets and discharges. The Air Act, 1981 similarly regulates industrial emissions, especially in air pollution control areas, and requires consent for industrial plants under Section 21. The Environment (Protection) Act, 1986 operates as an umbrella statute. Section 3 gives the Central Government wide power to take measures for environmental protection, while Section 5 authorises directions including closure, prohibition, regulation, and stoppage of services such as electricity or water. These statutes combine technical standards with administrative enforcement.

Passage or principleForest (Conservation) Act, 1980; Wild Life (Protection) Act, 1972; Biological Diversity Act, 2002

Forest, wildlife, and biodiversity laws protect overlapping but distinct ecological interests. The Forest (Conservation) Act, 1980 controls diversion of forest land and generally requires prior Central approval for dereservation or non-forest use. T.N. Godavarman expanded the operational understanding of forest to include dictionary forests and recorded forests. The Wild Life (Protection) Act, 1972 protects wild animals, birds, plants, and protected areas, and restricts hunting and trade in wildlife articles. The Biological Diversity Act, 2002 addresses conservation, sustainable use, and fair and equitable benefit sharing, especially where biological resources or associated knowledge are commercially used. Together these laws show that environmental law is not limited to pollution; it also governs land, habitats, species, and community-linked ecological knowledge.

Question 21MediumForest, Wildlife and Biodiversity

  1. A

    Registration of private timber sale contracts only.
