Article 21 and the Right to a Clean Environment

The Supreme Court has interpreted Article 21 to protect not merely survival, but a life of dignity in a healthy environment. Although the Article does not expressly mention the environment, the Court has treated the right to pollution-free air and water as part of the fundamental right to life.

Constitutional foundation

Article 21 states that no person shall be deprived of life or personal liberty except according to procedure established by law. The Court's environmental interpretation connects this enforceable fundamental right with constitutional duties concerning environmental protection.

• Article 48A directs the State to protect and improve the environment and safeguard forests and wildlife.
• Article 51A(g) makes protecting and improving the natural environment a fundamental duty of citizens.
• These provisions support the interpretation of Article 21, although Directive Principles and Fundamental Duties are not independently enforceable in the same way as fundamental rights.

Recognition of environmental quality as a right

In Subhash Kumar v. State of Bihar (1991), the Court stated that the right to life includes enjoyment of pollution-free water and air for the full enjoyment of life. Environmental pollution can therefore become a constitutional rights issue, rather than merely a breach of pollution-control legislation.

• A person may seek enforcement of this right through Article 32 when pollution impairs the quality of life.
• The Court has entertained public interest litigation concerning environmental harm, enabling issues affecting communities to receive judicial scrutiny.

Principles that make protection effective

In Vellore Citizens' Welfare Forum v. Union of India (1996), the Court recognised the precautionary principle and polluter pays principle as essential features of sustainable development.

• The precautionary principle requires preventive action against environmental degradation; lack of scientific certainty cannot justify postponing measures against threats of serious or irreversible damage.
• The polluter pays principle places responsibility on the polluter for compensating those harmed and meeting the cost of restoring the damaged environment.
• Sustainable development requires environmental protection to be integrated with development, rather than treating either as an unconditional overriding objective.

Application to noise pollution

In In Re: Noise Pollution (2005), the Court linked protection from excessive noise with Article 21, including peaceful living and sleep. Freedom of speech does not confer a right to force amplified sound upon unwilling listeners.

• This interpretation supports restrictions on noise, including noise from loudspeakers and firecrackers, to protect health and community well-being.
