The Evolution of Eco-Jurisprudence in India: An Approach to JudicialInter pretation of Environmental Rights

INTRODUCTION

In contemporary legal discourse, the right to a sustainable, safe and ecologically balanced environment is increasingly recognised as an immutable facet of fundamental human rights. While the text of the Constitution of India was originally silent on explicit environmental protections, the evolutionary trajectory of domestic environmental jurisprudence has been profoundly shaped by dynamic judicial activism. The jurisprudential shift toward constitutionalising environmental claims gained significant momentum during the 1980s and 1990s. This era was characterised by aggressive industrial expansion, which triggered severe ecological harm, including acute pollution, systemic deforestation and widespread habitat fragmentation. Faced with escalating public health crises and ecological imbalances, the Supreme Court of India and various High Courts assumed a transformative, regulatory role. Operating primarily through Public Interest Litigation (PIL), the judiciary harmonised the Directive Principles of State Policy and Fundamental Duties with Part III of the Constitution to read an implicit right to a healthy environment into the text. Prompted by an influx of public interest petitions from vigilant citizens and environmental activists, this judicial synthesis resulted in a series of path-breaking decisions that continue to serve as the bedrock of modern Indian environmental law.

This article traces that journey. It begins with India’s ecological traditions and the international conventions that shaped its legal framework, and then examines the constitutional provisions and landmark judgments through which environmental rights took root.

HISTORICAL PERSPECTIVE

The Ancient Period

Hindu scriptures such as the Vedas, Puranas and Upanishads describe trees, plants and wildlife in detail, showing their importance to human life; forests and trees held a high status in Hindu theology. Environmental care was central to Hindu life, and it is also reflected in the Indus Valley (Mohenjo-Daro, Harappa) and Dravidian civilisations, which lived in harmony with their ecosystems.

The Mauryan period is considered a high point for environmental protection in Indian history, with detailed legal provisions in Kautilya’s Arthashastra (traditionally dated 321–300 BC). Compensation was required for damage to productive forests. Pollution and littering were also punished: a penalty of 1/8 Pana for throwing waste on roads and 1/4 Pana for muddying water, with the penalty doubled if both offences occurred. Ashoka’s pillar edicts addressed the welfare of creatures in his state, prescribing fines for killing animals, even ants, squirrels and parrots.

The Medieval Period

Mughal emperors contributed to conservation by building gardens, orchards and parks around palaces, headquarters, public places and riverbanks. However, environmentalists note that, despite their love of nature, the Mughals made no real effort at forest conservation specifically.

The Pre-Independence Era

Early British rule brought the plunder of India’s natural resources and heavy deforestation. The British government began controlling Indian forests in 1806, and the late nineteenth century marked the start of organised forest management. The Indian Forest Act, 1865, the first major step toward a state monopoly, created “reserved forests” closed to the public and empowered the forest administration to penalise violations.

The Post-Independence Era

• Pre-1970: There was no cohesive environmental policy. The legal framework was limited to common law remedies (nuisance and negligence) and piecemeal provisions in laws such as the Indian Penal Code, 1860 (public nuisance) and the Factories Act, 1948. The primary focus was on industrial development and poverty alleviation.
• Post-1970: This was the Stockholm period, which witnessed significant development in international environmental law. The Stockholm Conference highlighted environmental protection concerns for the whole world, India included.

ANALYSIS OF THE STOCKHOLM CONFERENCE (1972)

The United Nations Conference on the Human Environment (UNCHE)¹ was held in Stockholm, Sweden. It was the first major attempt to address global environmental problems through international agreement between countries. Twenty-six principles were agreed upon and declared by the participating states, and these are known as the “Magna Carta on Human Environment”. The first few principles helped lay the foundation for the concept of “sustainable development”, to be achieved in order to safeguard the interests of future generations of mankind.

The key contributions of the conference are as follows:

• Declaration on the Human Environment: It addressed humankind’s relationship with the environment and the role of the environment in livelihood and in intellectual, social and spiritual growth. Its 26 principles covered:
  • the fundamental right to a healthy environment;
  • the duty to protect and improve the environment for present and future generations;
  • the State’s responsibility to prevent pollution and ensure a healthy environment for all living beings; and
  • the State’s obligation to cooperate in international pollution and environmental law.
• Action Plan for the Human Environment:
  • identifying problems in the global environmental crisis;
  • environmental management; and
  • supporting measures (education and training).
• World Environment Day: Established to be observed annually on 5 June.
• Resolution on Nuclear Weapon Tests: Condemned nuclear weapon tests and sought to prohibit atmospheric nuclear testing.
• Resolution on Institutional and Financial Arrangements:
  • Governing Council: to implement environmental programmes.
  • Environment Secretariat: to coordinate programmes and advise international bodies.
  • Environmental Coordination Board: to ensure efficient coordination of the United Nations Environment Programme (UNEP).
  • Voluntary Environmental Fund: to finance environmental programmes.

A decade later, the Nairobi Declaration (1982) marked Stockholm’s tenth anniversary, reaffirming its principles and identifying poverty and resource misuse as key drivers of environmental decline. This period also saw the UN Convention on the Law of the Sea (1982), the Vienna Convention on Ozone Layer Protection (1985) and the binding Montreal Protocol (1987), which controls ozone-depleting emissions.

In the same period, the Brundtland Commission Report (1987), “Our Common Future”, defined sustainable development as meeting present needs without compromising the ability of future generations to meet theirs. This, together with Stockholm, laid the groundwork for the Earth Summit (1992) in Rio de Janeiro, which produced the Rio Declaration, Agenda 21 (a sustainable development blueprint), conventions on Climate Change and Biodiversity, and the Forest Principles. Follow-up bodies included the UN Commission on Sustainable Development (1993), and a review session, Rio+5, was held in 1997.

The Second Earth Summit (2002), held in Johannesburg, addressed poverty, overpopulation and climate change through collective state cooperation. Later milestones included the Kyoto Protocol (adopted in 1997 and in force since 2005), the Copenhagen Accord (2009) and the Cancun Conference, which secured agreement on lowering industrial carbon emissions. The UN Conference on Sustainable Development, 2012 (the Rio+20 Summit), attended by delegations from 172 governments and numerous NGOs, reviewed two decades of progress; India supported its resolutions while urging greater support from developed nations for developing economies. Finally, the Paris Agreement (2015), adopted at the Conference of the Parties to the UN Framework Convention on Climate Change (UNFCCC), sought a binding, universal agreement to curb greenhouse gas emissions and slow global warming, limiting the rise in temperature to below 2°C, with further reductions targeted in later years. The commitments made were estimated to cap warming at 2.7°C by 2100.

THE IMPACT OF INTERNATIONAL ENVIRONMENTAL CONVENTIONS ON INDIA’S LEGAL FRAMEWORK

These international developments did not remain abstract commitments. Each of them left a visible imprint on Indian legislation, as the following sections show.

I. Stockholm Conference, 1972: The conference inspired the Indian Parliament to enact the following:

• the Water (Prevention and Control of Pollution) Act, 1974;
• the Forest (Conservation) Act, 1980;
• the Air (Prevention and Control of Pollution) Act, 1981; and
• the Environment (Protection) Act, 1986.

The concept of Environmental Impact Assessment (EIA) plays a very significant role in balancing the protection of the environment with economic growth. The concept gained international momentum following the Stockholm Conference in 1972 and was introduced in India in 1978 for a complete assessment of the environment, using various criteria, before the implementation of government projects. An EIA is mandatory before starting projects such as mining, river valley projects, thermal power, atomic power, airports, new towns and infrastructure.

II. The Brundtland Commission Report, 1987: The report mainly focuses on the concept of “sustainable development”. In Vellore Citizens Welfare Forum v. Union of India and Ors. (1996)², the Supreme Court of India, for the first time, recognised sustainable development as part of the law of the land and decided the case on the basis of the “precautionary principle” and the “polluter pays principle” of sustainable development. The importance of sustainable development was also emphasised by the Apex Court in various other cases, such as the Bichhri Village case³, Pradeep Krishen v. Union of India and Ors. (1996)⁴ and the Bhopal Gas Disaster case⁵. The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, was enacted to protect the rights of forest-dwelling communities who depend on forest produce. The concept of sustainable development also inspired Indian legislation to enact the Public Liability Insurance Act, 1991, to provide immediate relief to persons affected by accidents involving hazardous substances. It also paved the way for the Coastal Regulation Zone (CRZ) notification of 1991, which protects coastal areas and ocean resources from pollution.

III. The Earth Summit, 1992:

1. The Wild Life (Protection) Act, 1972, was amended in 2002 to meet the guidelines provided in the Earth Summit, 1992, for the protection of wildlife in reserved areas, as per the Rio Declaration on Environment and Development.
2. The Biological Diversity Act, 2002, was enacted to provide for the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of benefits arising out of the use of biological resources and knowledge.
3. The Protection of Plant Varieties and Farmers’ Rights Act, 2001, was enacted to recognise the contribution of private breeders as well as farmers in plant breeding activity.

IV. UNFCCC, 2015: India, being a signatory to the Paris Agreement, submitted its new action plan to the Convention. This document, the Intended Nationally Determined Contribution (INDC), sets out India’s plan to help prevent the average global temperature from rising by about two degrees Celsius, together with the measures to be taken by the Republic of India.

ENVIRONMENTAL CONSTITUTIONALISM IN INDIA

The original text of the Constitution of India lacked explicit provisions governing environmental conservation, as the post-independence legislature focused heavily on addressing acute poverty, civil rights and socio-economic infrastructure. This regulatory vacuum became unsustainable by the late 1960s, when aggressive industrialisation triggered widespread environmental degradation, including severe river pollution and forest depletion. The international legal paradigm shifted with the 1972 United Nations Conference on the Human Environment in Stockholm⁶. India’s active participation and commitment to the Stockholm Declaration served as the primary catalyst, obligating the State to execute a major constitutional course correction to integrate ecological governance into its supreme law.

Constitutional Provisions Relating to Environmental Protection

I. Article 21 (Right to Life and Environment): The Supreme Court has consistently held that the right to life includes the right to live in a pollution-free environment.

II. Directive Principles and Fundamental Duties (inserted by the Constitution (Forty-second Amendment) Act, 1976):

1. Article 48A directs the State to protect and improve the environment and safeguard forests and wildlife.
2. Article 51A(g) imposes a fundamental duty on citizens to protect the natural environment.

III. Environmental Protection under the Seventh Schedule: The Seventh Schedule of the Constitution distributes legislative powers between the Union and the States through three lists.

Union List (List I)

• Entry 52: Industries declared by Parliament to be of national importance (covers hazardous and polluting industries).
• Entry 53: Regulation and development of oilfields and mineral oil resources; petroleum and petroleum products.
• Entry 54: Regulation of mines and mineral development.
• Entry 56: Regulation and development of inter-State rivers and river valleys.
• Entry 97: Residuary powers (used to justify central environmental legislation such as the Environment (Protection) Act, 1986).

State List (List II)

• Entry 6: Public health and sanitation.
• Entry 14: Agriculture, protection of plants and prevention of pests.
• Entry 17: Water, water supplies, irrigation, canals and drainage.
• Entry 18: Land and land revenue.
• Entry 21: Fisheries.

Concurrent List (List III)

• Entry 17A: Forests.
• Entry 17B: Protection of wild animals and birds.

LANDMARK JUDGMENTS BY THE INDIAN JUDICIARY IN LINE WITH INTERNATIONAL NORMS

Together, these constitutional provisions gave the judiciary the textual foundation on which to build. The following judgments show how the courts used them, often in line with international environmental norms.

I. Rural Litigation and Entitlement Kendra v. State of UP⁷: This case involved illegal limestone mining in the ecologically sensitive Doon Valley. Mining activities caused deforestation, soil erosion and the depletion of water resources. The Supreme Court ordered the closure of environmentally harmful mines and held that environmental protection is part of the fundamental right to life under Article 21. This is widely regarded as the first environmental Public Interest Litigation in India, and it marked the beginning of judicial environmental activism.

II. MC Mehta v. Union of India (Ganga Pollution Case)⁸: This case was filed as a Public Interest Litigation by environmental activist M.C. Mehta under Article 32 of the Constitution, seeking judicial intervention to prevent pollution of the River Ganga. The petitioner highlighted that several tanneries in Kanpur were discharging untreated industrial waste directly into the river, making the water highly toxic and unsafe for human consumption.

The respondents argued that they lacked sufficient financial and technical resources to install effluent treatment plants. However, the Supreme Court rejected this argument and held that industries cannot be permitted to operate if they fail to take adequate measures to prevent environmental pollution. The Court observed: “Just like an industry which cannot pay minimum wages cannot be allowed to exist, a tannery which cannot set up a primary treatment plant cannot be permitted to continue.” The Court ordered the closure of polluting industries until they installed proper pollution control systems. It also directed municipal authorities to improve sewage systems, construct public sanitation facilities, and prevent the dumping of dead bodies and waste into the river. This case strengthened the principle that environmental protection takes precedence over industrial convenience.

III. Subhash Kumar v. State of Bihar⁹: In this case, the petitioner alleged that industrial pollution contaminated river water, affecting public health. The Supreme Court held that the right to pollution-free water and air is part of the fundamental right to life under Article 21. However, the Court dismissed the petition because it was filed for personal business interests rather than in the public interest. This case affirmed environmental protection as a fundamental right.

IV. Tarun Bharat Sangh v. Union of India¹⁰: This case involved illegal mining in the Sariska Tiger Reserve. The Supreme Court ordered the immediate closure of mining activities and directed environmental restoration measures. The Court emphasised the protection of forests, wildlife and ecological balance.

V. Vellore Citizens Welfare Forum v. Union of India¹¹: This landmark judgment is one of the most important decisions in Indian environmental jurisprudence, in which the Supreme Court explicitly recognised the concept of sustainable development as part of Indian law. The petitioner, Vellore Citizens Welfare Forum, filed a Public Interest Litigation under Article 32 of the Constitution against large-scale environmental pollution caused by tanneries operating in Tamil Nadu. These industries discharged untreated effluents into the River Palar, which was the primary source of drinking water, irrigation and domestic use for the surrounding population. Scientific studies conducted by the Tamil Nadu Agricultural University Research Centre revealed that approximately 35,000 hectares of agricultural land had become either totally or partially unfit for cultivation due to contamination.

The Court was confronted with a crucial question: whether economic development and industrial activity could be allowed to continue at the cost of environmental destruction and public health. The Supreme Court acknowledged that the leather industry was an important source of foreign exchange and employment. However, it held that economic development cannot be pursued at the expense of environmental protection and human health. The Court emphasised that sustainable development requires balancing environmental protection with developmental needs. It recognised and adopted three key principles as part of Indian environmental law:

• the Precautionary Principle;
• the Polluter Pays Principle; and
• the Sustainable Development Principle.

The Court directed all polluting tanneries to pay compensation for environmental damage and ordered the constitution of special environmental courts to ensure the speedy disposal of environmental disputes. This judgment firmly established sustainable development as an integral part of Indian constitutional and environmental law.

VI. S Jagannath v. Union of India¹²: This case addressed environmental damage caused by commercial shrimp farming along India’s coastal regions. The petitioner argued that shrimp farming caused groundwater contamination, the destruction of mangrove ecosystems and ecological imbalance. The Supreme Court held that coastal ecosystems are fragile and must be protected from environmentally harmful commercial activities. The Court applied the Precautionary Principle and the Polluter Pays Principle and ordered the closure of shrimp farms operating in ecologically sensitive areas. It also directed compensation to affected persons and ordered the establishment of regulatory authorities to monitor environmental compliance.

VII. Andhra Pradesh Pollution Control Board v. MV Nayudu¹³: In this case, an industry sought permission to establish a polluting unit near two major drinking water reservoirs supplying water to Hyderabad and Secunderabad. The Andhra Pradesh Pollution Control Board rejected the application due to environmental concerns. However, the High Court allowed the industry to proceed.

On appeal, the Supreme Court reversed the High Court’s decision and upheld the Pollution Control Board’s authority. The Court emphasised that environmental decisions must be guided by scientific expertise and precautionary principles, especially when public health and drinking water sources are involved. The Court recognised the Precautionary Principle as an essential component of environmental law and emphasised that a lack of scientific certainty cannot be used as a reason to permit environmentally harmful activities.

VIII. MC Mehta v. Union of India¹⁴: This case arose from the leakage of oleum gas from a chemical plant in Delhi, which caused death and injuries. The Supreme Court evolved the doctrine of Absolute Liability, which is stricter than the rule of Strict Liability established in Rylands v. Fletcher. The Court held that industries engaged in hazardous activities have an absolute and non-delegable duty to ensure safety. If harm occurs, they are absolutely liable to compensate victims. This case marked a turning point in Indian environmental law and strengthened industrial accountability.

IX. Indian Council for Enviro-Legal Action v. Union of India¹⁵: This case involved chemical industries that discharged highly toxic waste into soil and groundwater in Rajasthan, causing severe environmental damage and making agricultural land infertile. The Supreme Court applied the principle of Absolute Liability and held that industries engaged in hazardous activities are absolutely liable for environmental damage, regardless of fault or negligence. The Court ordered the closure of the polluting industries and directed them to pay compensation for environmental restoration. This case strengthened the Polluter Pays Principle in India.

RECENT JUDGMENTS RELATED TO ENVIRONMENTAL JURISPRUDENCE

The principles laid down in these landmark cases continue to guide the courts today. Two recent judgments illustrate how they are applied to contemporary regulatory questions.

I. M/S Indian Oil Corporation Limited v. V.B.R. Menon & Others (2023)¹⁶: The Supreme Court addressed the critical issue of air pollution from petroleum retail outlets. The Court upheld the National Green Tribunal’s directive requiring all petroleum retail outlets in cities with populations exceeding ten lakh and a monthly turnover exceeding 300 KL to install Vapour Recovery Systems (VRS).

The legal framework governing this directive stems from the Environment (Protection) Act, 1986, which empowers regulatory authorities to prescribe standards for emissions and pollution control. Section 25 of the Water (Prevention and Control of Pollution) Act, 1974, and Section 21 of the Air (Prevention and Control of Pollution) Act, 1981, provide the statutory foundation for such mandatory installation requirements. The Supreme Court’s judgment emphasised the precautionary principle, a fundamental tenet of environmental law established in Vellore Citizens Welfare Forum v. Union of India. The Court recognised that petroleum vapours constitute a significant source of volatile organic compounds that contribute to ground-level ozone formation and air quality deterioration in urban areas.

The technical specifications for VRS implementation were aligned with international standards, requiring Stage-I vapour recovery systems, which capture vapours during fuel delivery from tanker trucks to underground storage tanks, and Stage-II systems, which capture vapours during fuel dispensing to vehicle tanks. The Court’s directive established a timeframe for compliance and prescribed penalties for non-adherence, demonstrating the judiciary’s commitment to enforcing environmental standards.

II. K.T.V. Health Food Private Limited v. Union of India & Others (2023)¹⁷: The Supreme Court reinforced the prohibition on establishing storage facilities for edible oil outside designated port areas within the CRZ. This case highlighted the strict regulatory regime governing coastal areas under the Environment (Protection) Act, 1986.

The CRZ Notification classifies coastal areas into four categories with varying levels of permissible activities. The Court’s ruling emphasised that CRZ-I areas, which include ecologically sensitive zones, mangroves, coral reefs and areas between the high tide line and the low tide line, are subject to the most stringent restrictions. The establishment of industrial storage facilities in these areas contravenes the fundamental objectives of coastal protection and marine ecosystem conservation.

The legal principle established in this case reinforces the doctrine of sustainable development, which requires balancing economic development with environmental protection. The Court referred to the M.C. Mehta v. Union of India series of cases, which established that economic considerations cannot override environmental protection mandates when fragile ecosystems are at stake.

CONCLUSION

India’s eco-jurisprudence reflects a unique constitutional evolution: a text originally silent on environmental rights was transformed through judicial interpretation and is now firmly embedded within Article 21. This shift, catalysed by international developments such as the Stockholm Conference and the Rio Earth Summit, unfolded through decades of Public Interest Litigation. From the foundational recognition in Rural Litigation and Entitlement Kendra, through M.C. Mehta’s development of Absolute Liability, to Vellore Citizens Welfare Forum’s adoption of the precautionary and polluter pays principles, the judiciary has consistently positioned itself as the primary architect of environmental governance in India. Recent judgments confirm that this framework remains active and adaptable to contemporary issues.

However, this judiciary-driven model also exposes structural gaps (inconsistent enforcement, limited scientific capacity within courts, and weak coordination between Union and State authorities) that judicial activism alone cannot resolve. Strengthening legislative codification, building institutional capacity, improving Centre–State relations, integrating climate commitments domestically and expanding environmental awareness can strengthen environmental law in India and the world.
