Environmental challenges in India have often outpaced legislative and administrative measures. In this vacuum, the Supreme Court of India has played a pivotal role through judicial activism, stepping in to protect natural resources and citizens’ right to a healthy environment. By interpreting Article 21 of the Constitution (Right to Life) broadly, the Court has transformed environmental protection into a fundamental right and laid down guiding principles for governance.
Role of Judicial Activism in Environmental Protection
Judicial activism refers to the proactive role taken by the judiciary to enforce rights and expand the scope of justice beyond traditional interpretation. In the context of environmental law, this has meant:
- Expanding the Right to Life to include the right to clean air, water, and environment.
- Establishing doctrines such as Polluter Pays, Precautionary Principle, and Public Trust Doctrine.
- Using Public Interest Litigations (PILs) as a tool to involve citizens and NGOs in environmental justice.
- Holding governments and industries accountable for ecological degradation.
