Chapter 15 — Indian environmental law and institutions

Exam link: common foundation; exact provisions and amendments are date-sensitive.

Learning aim: connect constitutional principles, major environmental statutes and the roles of regulators, biodiversity bodies and the National Green Tribunal.

15.1 Constitutional foundations

Environmental governance in India draws on constitutional duties, legislation, rules, notifications, institutions and judicial decisions. The Constitution is not a detailed pollution-control manual; it establishes principles and responsibilities that Parliament and State legislatures implement through law.

Article 48A, in Part IV, directs the State to endeavour to protect and improve the environment and safeguard forests and wildlife. Article 51A(g), in Part IVA, states a fundamental duty of citizens to protect and improve the natural environment, including forests, lakes, rivers and wildlife, and to have compassion for living creatures. Both were inserted by the Constitution (Forty-second Amendment) Act, 1976; the relevant provisions took effect on 3 January 1977. The first is a Directive Principle; the second is a citizen duty. They are not interchangeable with a statutory permit or a site-specific restriction.

The Supreme Court has also interpreted environmental protection through constitutional rights and public-law principles. Such doctrine develops through judgments and context. A study guide can explain that courts have treated environmental quality as connected to life and public health, but it should not reduce a complex case to the statement “every environmental issue is an Article 21 violation.” Use the judgment, facts and remedy relevant to the question.

15.2 The Environment (Protection) Act, 1986

The Environment (Protection) Act, 1986 provides a broad central framework for protecting and improving the environment. It empowers the Central Government to take measures and make rules within the Act's provisions. Many detailed standards and waste-management rules are notified under this umbrella. The Act should not be confused with every rule made under it: a statute provides the enabling framework, while subordinate legislation supplies specific requirements.

The law's scope and application are read with amendments, rules and notifications. As of the stated edition cutoff, the Environment (Protection) Act has also been amended in recent years, including changes affecting penalty provisions. This book focuses on institutional and process concepts; it does not reproduce old penalty tables. Any future penalty question must use the consolidated text in force on the exam date.

15.3 Water and air pollution-control laws

The Water (Prevention and Control of Pollution) Act, 1974 established a statutory framework for preventing and controlling water pollution and maintaining or restoring water quality. It provides for Central and State Pollution Control Boards and assigns them functions under the Act. The Air (Prevention and Control of Pollution) Act, 1981 provides a corresponding statutory framework for prevention, control and abatement of air pollution and board functions.

The Central Pollution Control Board (CPCB) works at the national level; State Pollution Control Boards (SPCBs) operate within the applicable state legal framework. Functions can include setting or recommending standards where authorized, monitoring, technical advice, coordination, consent administration and enforcement under the relevant Act and rules. The precise power depends on the statute, amendment, notification and delegation; a board's portal page is not a replacement for the law.

The Water Act was amended in 2024. Because it was enacted under Article 252 and subsequent resolutions can affect state application, the amendment's territorial application and commencement must be checked for each state before making a current claim. The book will avoid an undated statement that every amendment applies identically in every state. For pollution-control practice questions, identify which board and which statute the scenario actually invokes.

15.4 Forest, wildlife and biodiversity statutes

The Wild Life (Protection) Act, 1972 provides the statutory basis for listed wildlife protections, protected-area categories, authorities and regulated activities. The 2022 amendment commenced on 1 April 2023. It changed schedules and added or revised provisions, including one concerning invasive alien species. A current question should be checked against the consolidated amended law, not an old bare-act summary.

The Forest (Conservation) Act, 1980 was amended in 2023 and renamed the Van (Sanrakshan Evam Samvardhan) Adhiniyam. Its title, definitions, scope and exceptions should be checked in the 2023 amending Act and subsequent notifications. Do not use the older title as if no amendment occurred, and do not infer that this statute alone establishes every person's rights or forest status.

The Biological Diversity Act, 2002 provides a framework for conservation, sustainable use and fair and equitable sharing of benefits associated with biological resources and knowledge. Its institutions include the National Biodiversity Authority (NBA), State Biodiversity Boards and Biodiversity Management Committees, with functions defined by statute and rules. The Act was amended in 2023 and Biological Diversity Rules, 2024 were notified. Before publication, exact provisions and exemptions must be checked in the amended text and rules.

15.5 National Green Tribunal

The National Green Tribunal (NGT) was established under the National Green Tribunal Act, 2010 to adjudicate specified civil cases involving substantial environmental questions and matters arising under the laws listed in the Act. It also has statutory appellate jurisdiction in specified matters. The Act provides for relief, compensation and restitution in relevant cases and directs the Tribunal to apply specified principles.

The NGT does not replace every environmental authority or ordinary court for every dispute. Jurisdiction depends on the Act, the legal provision, the kind of order challenged, limitation rules and case facts. A basic exam question may ask its establishing Act or broad role; a procedural question requires current statutory text and case law.

15.6 A simple institutional map

• MoEFCC: central ministry responsible for national environment, forest and climate policy and for specified approvals and notifications.
• CPCB: central statutory board under pollution-control laws, with national coordination, monitoring and technical functions.
• SPCB/PCC: state/UT pollution-control institutions, with roles assigned under applicable pollution laws and delegated processes.
• NBA: national statutory body under the Biological Diversity Act.
• State Biodiversity Board: state-level biodiversity institution under the Act.
• Biodiversity Management Committee (BMC): local statutory body; biodiversity registers and other functions are governed by the amended Act/rules.
• Chief Wildlife Warden / state forest authorities: statutory and administrative roles under wildlife/forest frameworks.
• NGT: tribunal for specified environmental disputes and appeals under its establishing Act.
• Local bodies and communities: important for waste, land-use, local water systems, biodiversity documentation and stewardship under the relevant laws and schemes.

These bodies do not form a single command chain. A pollution complaint, a forest-clearance question, a wildlife offence and a biodiversity-access issue may involve different authorities and procedures. Read the subject of the case before identifying the institution.

15.7 Principles used in environmental governance

The precautionary principle supports preventive action where there is a credible risk of serious harm despite scientific uncertainty; it does not mean that every uncertain claim automatically proves liability. The polluter-pays principle places relevant prevention or remediation costs on the polluter under applicable law and jurisprudence. Sustainable development seeks to integrate environmental protection with social and economic needs. Public trust doctrine treats certain natural resources as held in trust for public use and future generations in relevant legal contexts.

These principles have been shaped by legislation and court decisions. Their application depends on facts, legal authority and remedy. They are not four universal statutory offences or a substitute for compliance procedure.

15.8 Read the source in the right order

When a question asks whether an activity is allowed, proceed from the most specific controlling source:

1. Identify the location, resource and activity.

2. Find the applicable Act and section.

3. Check rules, schedules and current amendments.

4. Read the Gazette notification or order for the site, project or standard.

5. Check the responsible authority and any appeal path.

6. Note the effective date and territorial scope.

A ministry webpage can point to the relevant document but may not be updated when a rule changes. A draft notification is not the final rule. A court order may change how a rule is applied. For a current exam, the final notification and authoritative text take precedence over an old summary.

Figure 15.1 — Institution-to-law map: connect pollution laws to CPCB/SPCB; biodiversity law to NBA/SBB/BMC; wildlife law to wildlife authorities and protected areas; EPA rules/notifications to the Central Government and specified authorities; NGT to listed statutes and appellate/relief functions. Use two-way arrows for coordination and appeals, not a single top-down chain.

Worked case: industrial discharge complaint

Residents report discoloured water downstream of a facility. The first step is evidence and jurisdiction, not an assumed legal conclusion. Record the location, time, flow and observable conditions; preserve samples through an accepted protocol; identify the discharge point and receiving water; and contact the competent pollution-control authority. Whether the Water Act, Environment (Protection) Act rules, consent conditions or another law applies depends on the facility, permit and discharge. If an order is issued, any appeal forum and time limit must be taken from the controlling legal provision. The NGT is not automatically the first office for every complaint.

Exam traps and retrieval

• Article 48A is a Directive Principle; Article 51A(g) is a Fundamental Duty.
• An Act, rule, notification and draft are different legal instruments.
• CPCB and SPCBs have statutory roles, but their powers depend on the applicable Act and delegation.
• A 2024 amendment's territorial application must be checked; do not assume uniform coverage without a commencement/application source.
• NGT jurisdiction is statutory and specified, not universal.
• Current titles and amendment status matter: Wildlife Act amended in 2022; Forest law renamed/amended in 2023; Biodiversity Act amended in 2023 with 2024 Rules.
• A ministry webpage or study note is not a substitute for the controlling Gazette text.

Without looking, identify the constitutional location of Article 48A and Article 51A(g), name one function of CPCB/SPCB, and state one reason a draft ESZ notification cannot prove a final boundary. Then outline the source order for checking a current protected-area activity restriction.
