Step 1: Understanding the Kamal Nath Case.
In the Kamal Nath case (1997), the Supreme Court held that the Public Trust Doctrine, which ensures that natural resources are held in trust for the benefit of the public, applies to the management of public resources. The court emphasized that the state has a duty to manage such resources for the welfare of the public.
Step 2: Explanation of Other Options.
- (a) The Basic Future and Basic Structure Doctrine are not part of the Kamal Nath case's conclusions.
- (c) Separation of power doctrine is a general constitutional principle but was not the focus of this case.
- (d) While the case is public interest litigation, the Public Trust doctrine was central to the judgment.
Step 3: Conclusion.
The Kamal Nath case evolved the Public Trust Doctrine to protect natural resources.
