SC Extends ‘Public Trust Doctrine’ to Man-made Lakes

On October 9, 2025, the Supreme Court expanded the scope of environmental protection by ruling that the Public Trust Doctrine applies to man-made lakes and reservoirs, not just natural water bodies. The verdict came in a plea involving Futala Lake in Nagpur.

The ruling prevents governments or authorities from treating public ecological resources as ordinary property. Even if a water body is man-made, it can still serve public and ecological functions and therefore deserves legal protection.

Key Highlight	Elaborated Explanation
State as Trustee	The Court reaffirmed that the government is a trustee of natural resources such as air, water and forests, and must protect them for public use rather than private ownership.
Expansion of Scope	Even if a lake is man-made or does not qualify as a “wetland” under the 2017 Rules, it remains protected under the public trust if derived from natural resources.
Usage Restrictions	Resources under public trust must be used only for public purposes. They cannot be sold to private parties and must be preserved for ecological utility.
Sustainable Development	The Supreme Court emphasized balancing progress with environmental integrity to ensure intergenerational equity.
