2. The River Boards Act (1956) was enacted by the Parliament under the provision of Article 262, to set up boards in order to settle disputes with respect to sharing waters of inter-state rivers.
3. The decision of the tribunal set up for the adjudication of inter-state water disputes under the Act is subject to appeal in the High Court of the concerned states.
4. The need for an extra-judicial machinery to settle inter-state water disputes is based on the experience that legal rights or interests in water supplies do not afford a satisfactory basis for settling disputes between states where public interests are involved.
