The public trust doctrine and sustainable development: An aspect of environmental law

The objective of this study is to introduce the public trust doctrine and to examine its application in relation to sustainable development. To facilitate this study judgments of the superior courts of Sri Lanka, India, the United States and several other countries are referred to.

The international instruments relating to environment demonstrate the concern of the international community for a healthy environment for all life forms including human beings through sustainable development. Sustainable development according to Bruntland Report (1987) is the development that meets the needs of the present without compromising the ability of the future generations to meet their own needs. The public trust doctrine is an essential element of judicial process to facilitate towards sustainable development.

The public trust doctrine in essence means that powers vested in public authorities are not absolute or unfettered but are held in trust for the public, to be exercised for the purposes for which they have been conferred and that their exercise is subject to judicial review by reference to those purposes. Administrative acts and decisions contrary to the public trust doctrine and\or violative of human rights would be in excess or abuse of power and therefore void. The Court expressed the view that in such judicial review the historical English law limitations on prerogative writs are no longer applicable, because now Sri Lankan courts not courts of the Crown but are bound by the public trust doctrine and are subject to fundamental rights.

Undoubtedly the State has the right to exploit its own resources pursuant, however, to its own environmental and developmental policies and laws. Rational planning constitutes an essential tool for reconciling any conflict between the needs of development and the need to protect and improve the environment. Human beings are at the centre of concern for sustainable development. In order to achieve sustainable development, decision making process must also comply with public trust doctrine.
