Inter-state Dispute Resolution Mechanism
- Attempts are usually made to resolve inter-state disputes with the cooperation of both sides, with the Centre working as a facilitator or a neutral mediator.
Constitutional methods to resolve the inter-state disputes:
- Judicial redressal: As per the Article 131 of the Constitution the Supreme Court in its original jurisdiction decides disputes:
- between the Government of India and one or more States; or
- between the Government of India and any State or States on one side and one or more other States on the other; or
- between two or more States.
- Inter-state Council: Article 263 of the Constitution gives powers to the President to set up an Inter-state Council for the resolution of disputes between states.
- The Council is envisaged as a forum for discussion between the states and the Centre. In 1988, the Sarkaria Commission suggested that the Council should exist as a permanent body, and in 1990 it came into existence through a Presidential Order.
- Functions of the Council:
- inquiring into and advising upon disputes which may have arisen between States;
- investigating and discussing subjects in which some or all of the States, or the Union and one or more of the States, have a common interest; or
- making recommendations upon any such subject and, in particular, recommendations for the better coordination of policy and action with respect to that subject.
- In 2021, the Centre reconstituted the Inter-state Council and the body now has 10 Union Ministers as permanent invitees.
- The standing committee of the Council has been reconstituted with Home Minister as Chairman. The finance minister and the Chief Ministers of Maharashtra, UP, and Gujarat are some of the other standing committee members.
