Fundamental Rights and the Environment: How Article 21 Expands to Include Environmental Rights

The Indian Constitution, when it was adopted in 1950, did not explicitly mention the word “environment” anywhere in its text. Yet today, the right to a clean and healthy environment is treated as a fundamental right in India. How did that happen? The answer lies largely in the judicial evolution of Article 21 – a provision that simply states, “No person shall be deprived of his life or personal liberty except according to procedure established by law.” Through decades of progressive court rulings, this short sentence has become one of the most powerful legal tools for environmental protection in the country.

What Article 21 originally meant 🔗

At the time of its adoption, Article 21 was understood in a narrow sense. It guaranteed the right to life and personal liberty, primarily serving as a safeguard against arbitrary state action – like unlawful detention or deprivation of life without legal authority. The scope of “life” was limited to physical survival, and “procedure established by law” meant any law passed by the legislature, regardless of its fairness.

This restrictive reading persisted for nearly three decades. Although the original Constitution did not explicitly guarantee environmental rights, judicial interpretation has expanded the scope of Article 21 to include the right to a clean and healthy environment. The shift began with a series of landmark Supreme Court decisions in the late 1970s and 1980s.

The turning point: Maneka Gandhi v. Union of India (1978) 🔗

The transformation of Article 21 started with the case of Maneka Gandhi v. Union of India (1978). While not an environmental case itself, this ruling fundamentally changed how Indian courts interpreted the right to life. This interpretation was gradually developed through landmark judgments, beginning with Maneka Gandhi v. Union of India (1978), which broadened the meaning of “life” beyond mere physical existence. The Supreme Court held that the procedure depriving someone of life or liberty must be fair, just, and reasonable – not merely any procedure that parliament decided upon.

This opened the floodgates. After the Maneka Gandhi decision, the courts began reading a wide range of unenumerated rights into Article 21 – the right to livelihood, the right to privacy, the right to shelter, the right to health, and eventually, the right to a clean environment. The word “life” was no longer confined to mere biological existence; it now meant a life of dignity.

The Dehradun quarrying case: environment meets fundamental rights 🔗

The first major case to directly connect environmental protection with Article 21 was Rural Litigation and Entitlement Kendra v. State of U.P. (1985), commonly known as the Dehradun Quarrying Case or the Doon Valley Case.

Background of the case 🔗

The Mussoorie-Dehradun belt, once known for its pristine natural beauty and rich biodiversity, faced a severe ecological crisis in the early 1980s due to rampant limestone quarrying. The uncontrolled extraction of limestone using dynamite led to deforestation, landslides, soil erosion, water pollution, and the destruction of agricultural land. Local communities suffered health hazards and loss of livelihoods.

Rural Litigation and Entitlement Kendra (RLEK), a local non-governmental organisation in Dehradun, wrote a letter to the Supreme Court in July 1983 alleging illegal mining operations that were creating environmental and ecological imbalances in the region. The Supreme Court converted this letter into a writ petition under Article 32 – a key moment in Indian environmental law history.

What the Supreme Court decided 🔗

The Court appointed the Bhargav Committee to inspect the quarries. The committee divided all limestone quarries into three categories according to the grade of adverse impact of the mining operations. Category A quarries had the least harm, Category B had moderate harm, and Category C were the most damaging. The Court ordered the closure of several limestone quarries in the Dehradun valley to prevent further environmental degradation and recognized that the right to a clean and healthy environment is a part of the right to life under Article 21.

The Court also tried to balance economic interests with ecological protection. It emphasized that afforestation and soil conservation programmes would have to be taken up in the closed quarries and ordered the government to provide employment to displaced workmen in these programmes.

This case was groundbreaking because it established that environmental destruction can directly violate fundamental rights. The Supreme Court made it clear that ecological balance is not a luxury but a constitutional necessity.

M.C. Mehta cases: building the framework 🔗

If one individual’s name is synonymous with environmental Public Interest Litigation in India, it is M.C. Mehta. Through a series of cases spanning from the mid-1980s to the present, environmental lawyer M.C. Mehta brought numerous pollution-related matters before the Supreme Court.

In M.C. Mehta vs. Union of India (AIR 1987 SC 1086), the Supreme Court treated the right to live in a pollution-free environment as a part of the fundamental right to life under Article 21. This case, arising from the Shriram gas leak disaster in Delhi, is often compared in significance to the Bhopal gas tragedy. The Court not only held that hazardous industries must compensate victims but also developed the absolute liability principle – a stricter standard than what existed under common law.

Other M.C. Mehta cases tackled Ganga river pollution, vehicular emissions in Delhi, groundwater contamination in Rajasthan, and the Taj Mahal’s degradation from industrial pollution. Together, these cases wove environmental protection deeply into the fabric of constitutional rights.

Subhash Kumar v. State of Bihar (1991): right to clean water and air 🔗

The case of Subhash Kumar v. State of Bihar (1991) is another essential milestone, even though the petition itself was dismissed. Subhash Kumar filed a PIL alleging that the Tata Iron and Steel Company was discharging industrial slurry into the Bokaro river, polluting the water and affecting the health and livelihood of local communities.

The Supreme Court held that the right to live is a fundamental right under Article 21 and it includes the right of enjoyment of pollution-free water and air for full enjoyment of life. The Court further stated that if anything endangers that quality of life in violation of laws, citizens have the right to approach the Supreme Court under Article 32 to seek removal of such pollution.

However, the judgment also warned against abuse of PILs, noting that courts must ensure PILs are filed in good faith and not for personal or political gain. In this particular case, the Court found that the petitioner had personal commercial motives rather than a genuine public interest. Despite dismissing the petition, the legal principle it established became a cornerstone of environmental jurisprudence in India.

The constitutional support system: Articles 48A and 51A(g) 🔗

The judicial expansion of Article 21 did not happen in isolation. Two other constitutional provisions – introduced by the 42nd Amendment in 1976 – played a crucial supporting role.

Article 48A: directive for the state 🔗

Article 48A, a Directive Principle of State Policy, places a duty on the State to protect and improve the environment and safeguard forests and wildlife. While Directive Principles are not directly enforceable in court, the Supreme Court has consistently read Article 48A together with Article 21 to strengthen the constitutional case for environmental protection.

Article 51A(g): duty of every citizen 🔗

Article 51A(g) says that it shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers, and wildlife, and to have compassion for living creatures. This Fundamental Duty, though also not directly enforceable, has been used by courts to reinforce the idea that environmental responsibility is both a state obligation and a civic duty.

The Supreme Court’s strategy has been to read these three provisions – Articles 21, 48A, and 51A(g) – as a unified constitutional mandate for environmental protection. In Subhash Kumar v. State of Bihar (1991), the Supreme Court combined Articles 48A and 51A(g) with Article 21, ruling that the state must protect and improve the environment so that every citizen can enjoy pollution-free air and water essential for a meaningful life.

Life beyond physical survival: the dignity dimension 🔗

What makes the judicial expansion of Article 21 particularly significant is its emphasis on the quality of life rather than just the existence of life. The Supreme Court has made it clear on multiple occasions that mere animal existence does not fulfil the constitutional guarantee under Article 21.

The right to life was extended to include the right to survive as a species, quality of life, the right to live with dignity, right to a good environment, and the right to livelihood. This means that breathing polluted air, drinking contaminated water, or living near hazardous waste does not count as “life” under the Constitution – it is a violation of it.

This interpretation has had far-reaching consequences. It shifts the burden on the state and private entities to ensure that their actions do not degrade the environment to an extent that it compromises human dignity. Development can proceed, but not at the cost of making life unlivable.

The latest chapter: climate change as a fundamental right (2024) 🔗

The journey of Article 21 has not stopped. In the landmark case of M.K. Ranjitsinh v. Union of India (2024), the Supreme Court went a step further. For the first time, the Court recognized that the right to be free from the adverse effects of climate change is integral to the fundamental rights enshrined under Articles 21 and 14 of the Indian Constitution.

The case originally concerned the protection of the endangered Great Indian Bustard from solar energy infrastructure. But the Court used it as an opportunity to address India’s broader obligations under international environmental conventions and climate justice. The Court built upon earlier precedents such as Virender Gaur v. State of Haryana (1994) and M.C. Mehta v. Kamal Nath (2000), where the Court had linked environmental integrity directly with the right to life.

This ruling places India within a growing global movement toward treating environmental protection as a human right. Over 155 countries have incorporated some form of the right to a healthy environment through constitutional provisions, statutory law, or regional human rights treaties.

Key legal principles that emerged 🔗

Through these decades of judicial activism, several important legal principles have become part of India’s environmental law framework:

Polluter pays principle: This principle makes polluters financially responsible for managing their pollution, including compensation for environmental damage. It was notably applied in the Vellore Citizens’ Welfare Forum v. Union of India (1996).

Precautionary principle: The precautionary principle requires the state to take preventive action against serious environmental threats, promoting sustainable development over a simple choice between development and ecology.

Public trust doctrine: Natural resources like air, water, forests, and seas are held by the state as a trustee for the public. The state cannot allow them to be exploited or destroyed for private gain. This was established in M.C. Mehta v. Kamal Nath (1997), where the Court held that leasing ecologically fragile land to private parties constituted a breach of public trust.

Why this matters today 🔗

India faces severe environmental challenges – 13 of the 20 most polluted cities worldwide are in India, according to the World Air Quality Report 2024. Water scarcity is escalating, biodiversity is declining, and climate change is making extreme weather events more frequent. In this context, the judicial expansion of Article 21 provides a critical legal tool for holding both the government and private actors accountable.

The establishment of the National Green Tribunal (NGT) in 2010 further strengthened this framework by creating a dedicated judicial body for swift resolution of environmental disputes. The NGT was established under the National Green Tribunal Act of 2010 to quickly resolve cases related to environmental preservation and the conservation of natural resources.

However, challenges remain. Despite progressive judicial interpretation, the absence of an explicit fundamental right to a healthy environment limits enforceability. Some legal scholars argue that formally incorporating this right into Part III of the Constitution would strengthen environmental governance by clearly defining state accountability and citizen responsibility.

What do you think? Should India amend its Constitution to explicitly include the right to a clean environment as a fundamental right, or has judicial interpretation under Article 21 been sufficient? As environmental crises intensify, is it time to move from implied rights to clearly stated constitutional guarantees?
