The Supreme Court of India has ruled that the public trust doctrine applies not only to natural waterbodies such as rivers, lakes and wetlands but also to man‑made reservoirs and tanks that serve ecological functions. The judgement arose from a case concerning construction around Futala Lake in Nagpur.
Background
The public trust doctrine is a legal principle rooted in Roman and English common law. It holds that certain resources of fundamental importance—such as waterbodies, forests and wildlife—are held in trust by the state for the benefit of the public. The doctrine requires governments to protect these resources and prevents them from being permanently transferred to private ownership. In India, Articles 48‑A and 51‑A(g) of the Constitution provide a basis for environmental protection and have been used by courts to uphold the doctrine.
Supreme Court’s observations
- Inclusion of artificial waterbodies: The Court held that all man‑made waterbodies created from natural resources and contributing to ecological balance fall under the public trust doctrine.
- Environmental protection over classification: The bench noted that even if a reservoir or tank does not meet the statutory definition of a “wetland,” it still deserves protection if it provides environmental benefits. The purpose of the public trust doctrine is to ensure that resources vital to ecological health remain available for public use.
- Responsibility of authorities and citizens: The Court emphasized that both government agencies and citizens must safeguard natural and artificial waterbodies. Development activities should not compromise ecological integrity, and any construction must be carried out responsibly.
Significance
- Broader environmental protection: By extending the public trust doctrine to artificial lakes and reservoirs, the judgement strengthens legal safeguards for urban waterbodies that are increasingly threatened by development.
- Guidance for policy makers: The ruling encourages authorities to integrate ecological considerations into urban planning and infrastructure projects.
- Citizen empowerment: Residents and environmental groups can invoke the doctrine to protect local lakes, tanks and wetlands from encroachment and pollution.
