Green Constitution: Judicial Activism and Environmental Protection in India

INTRODUCTION

Environmental protection has emerged as one of the most pressing needs of modern civilisation. Rapid industrialisation, urban expansion, and the exploitation of natural resources have endangered the ecological balance. In India, the Constitution did not originally contain detailed environmental provisions, yet over time, it has evolved into what scholars call a “Green Constitution.” This transformation has largely been driven by judicial activism, where the courts have interpreted constitutional guarantees—especially the Right to Life under Article 21—to include the right to a clean and healthy environment. The Indian judiciary has played a proactive role in ensuring that development does not come at the cost of environmental degradation.

Constitutional Framework for Environmental Protection

Although the framers of the Constitution did not include a specific fundamental right to the environment, the 42nd Constitutional Amendment of 1976 added crucial provisions that turned the Indian Constitution into an environmentally conscious document.

• Article 48-A (Directive Principles of State Policy) directs the State to protect and improve the environment and safeguard forests and wildlife.
• Article 51-A(g) imposes a fundamental duty on every citizen to protect and improve the natural environment, including forests, lakes, rivers, and wildlife.
• Together, these provisions establish a moral and legal responsibility on both the government and the citizens to maintain ecological harmony.
• However, the true constitutionalisation of environmental rights happened when the Supreme Court expanded the interpretation of Article 21, holding that the right to life means the right to live in a pollution-free, safe and sustainable environment.

Judicial Activism: Meaning and Role

Judicial activism refers to the dynamic role of the judiciary in filling gaps left by the legislature or executive, especially when fundamental rights are at stake. In India, judicial activism has been instrumental in developing environmental jurisprudence through Public Interest Litigations (PILs). These PILs have allowed ordinary citizens, NGOs, and activists to approach the courts in matters concerning environmental protection without the traditional limitations of “locus standi.” The judiciary has thus emerged as the guardian of the environment, transforming constitutional ideals into enforceable rights and duties. Through landmark rulings, the courts have established guiding principles like the Polluter Pays Principle, Precautionary Principle, and Sustainable Development.

Landmark Judicial Decisions

1. Rural Litigation and Entitlement Kendra v. State of Uttar Pradesh (1985)
   This was India’s first major environmental case, concerning limestone quarrying in the Mussoorie Hills. The Supreme Court ordered the closure of quarries that were causing ecological imbalance, recognising the need to protect the environment over economic gain.
2. M.C. Mehta v. Union of India (Oleum Gas Leak Case, 1986)
   Following a gas leak from a Delhi factory, the Court introduced the doctrine of Absolute Liability, holding that industries engaged in hazardous activities must compensate victims, irrespective of negligence. This landmark ruling strengthened environmental accountability.
3. M.C. Mehta v. Union of India (Ganga Pollution Case, 1988)
   The Court directed the closure of tanneries and other industries discharging untreated waste into the River Ganga. It declared that the right to clean water is a part of the right to life under Article 21.
4. M.C. Mehta v. Kamal Nath (1997)
   The Court introduced the Public Trust Doctrine, declaring that the State holds natural resources in trust for the people and cannot convert them for private use.
5. T.N. Godavarman Thirumulpad v. Union of India (1997 onwards)
   Through a continuing series of orders, the Supreme Court redefined the scope of the term “forest,” regulated deforestation, and protected wildlife sanctuaries across the country.
6. Narmada Bachao Andolan v. Union of India (2000)
   The Court balanced the need for development with environmental protection, emphasising sustainable development as the guiding principle for decision-making.

Judicially Developed Environmental Principles

Through decades of rulings, Indian courts have developed a strong set of doctrines that guide environmental governance:

1. Polluter Pays Principle: The polluter must bear the cost of cleaning up pollution and compensating victims.
2. Precautionary Principle: Lack of full scientific certainty should not be used as a reason for postponing preventive measures against environmental degradation.
3. Sustainable Development: Economic growth must proceed without compromising the environmental and social needs of future generations.
4. Public Trust Doctrine: Natural resources like air, water, and forests belong to the public, and the government acts merely as a trustee.
5. Inter-generational Equity: The present generation has a duty to preserve natural resources for the benefit of future generations.
6. These principles now form the backbone of India’s environmental jurisprudence and are routinely cited in judicial decisions and policy frameworks.

Public Interest Litigation (PIL) and Citizen Participation

The introduction of PILs revolutionised environmental law enforcement in India. The judiciary relaxed the traditional rule of “locus standi,” allowing concerned citizens or organisations to approach the court on behalf of affected communities or even future generations. This participatory approach democratised environmental justice and made courts accessible to marginalised groups. Through PILs, the Supreme Court and High Courts have intervened in issues such as river pollution, vehicular emissions, illegal mining, deforestation, and waste management. This proactive stance has often compelled governments and corporations to adopt environmentally responsible practices.

Impact of Judicial Activism

Judicial activism has profoundly changed the way India perceives environmental governance. The courts have:

• Recognised environmental protection as a fundamental right under Article 21.
• Pressured the executive to implement laws effectively.
• Created mechanisms like the National Green Tribunal (NGT) to ensure specialised and speedy environmental justice.
• Integrated international environmental law principles—such as those from the Stockholm (1972) and Rio (1992) Declarations—into domestic law.

In doing so, the judiciary has acted not only as a protector of the environment but also as a catalyst for legislative and administrative reform.

Challenges and Criticisms

Despite these achievements, judicial activism faces several challenges:

• Judicial Overreach: Critics argue that courts sometimes cross their constitutional limits by performing executive functions.
• Implementation Gap: Many judicial orders remain unimplemented due to weak administrative capacity and a lack of political will.
• Economic Concerns: Stringent judicial orders occasionally affect industrial productivity and employment.
• Technical Limitations: Courts are not always equipped with scientific expertise to decide complex environmental issues.
• Nevertheless, the judiciary’s intervention has been essential in a system where environmental governance is often undermined by bureaucratic inefficiency and corruption.

Conclusion

The evolution of India’s Green Constitution is a shining example of how judicial activism can bridge the gap between law and life. By interpreting constitutional provisions in light of environmental realities, the judiciary has transformed the right to life into a right to a healthy and sustainable environment. Judicial activism has not only protected natural resources but also awakened public consciousness about ecological preservation. Today, the courts continue to remind the nation that development and environment are not opposing goals but complementary paths toward sustainable progress. The Indian judiciary, through its visionary approach, has ensured that environmental protection remains at the heart of constitutional governance—turning the Constitution truly green in spirit, vision, and practice.
