Public Trust Doctrine:
Public Trust Doctrine primarily rests on the principle that certain resources like air sea, waters and the forests have such a great importance to the people as a whole that it would be wholly unjust to make them a subject of private ownership. The said resources being a gift of nature, they should be made freely available to everyone irrespective of the status in life. The doctrine enjoins upon the Government to protect the resources for the enjoyment of the general public rather than to permit their use for private ownership or commercial purposes.
