Study Note

BackgroundCore Concept

Background

Inter-state river water disputes are among the most persistent governance challenges in India's federal structure. Water is listed under Entry 17 of the State List (Seventh Schedule), making it primarily a state subject. However, Entry 56 of the Union List empowers Parliament to regulate inter-state rivers when declared expedient in the public interest. This constitutional tension between state sovereignty over water and Union oversight of shared rivers is the root cause of most inter-state disputes.

Article 262 of the Constitution addresses this tension directly. It empowers Parliament to provide for the adjudication of disputes relating to the use, distribution, or control of inter-state river waters. Crucially, it also bars the jurisdiction of the Supreme Court and other courts in such matters. Parliament enacted the Inter-State River Water Disputes Act (ISRWDA), 1956 under this authority. Under this Act, the Union Government can constitute a tribunal when a state makes a request and negotiations fail. Tribunal awards, once published in the Official Gazette, carry the force of a Supreme Court decree.

Despite this statutory framework, tribunals have proved slow and adversarial. The Cauvery Water Disputes Tribunal took 17 years to deliver its award. This delay has pushed states and the Centre toward negotiated, MoU-based settlements as a faster alternative. Such agreements reflect the broader principle of cooperative federalism, where states resolve shared problems through dialogue rather than litigation.

The Topic Explained

The ISRWDA, 1956 lays down a clear procedure. A state government requests the Union Government to refer a dispute to a tribunal. The Union must first attempt resolution through negotiation. Only if negotiations fail does it constitute a tribunal. Once constituted, a tribunal's award is binding and published in the Official Gazette. However, implementation has often lagged even after awards, as seen in the Cauvery dispute.

The constitutional design also provides Article 263, which allows for an Inter-State Council (ISC) to coordinate between states and the Centre. The ISC has emerged as a preferred forum for negotiated settlements. The Central Water Commission (CWC), a technical body under the Ministry of Jal Shakti, plays a critical supporting role. It provides hydrological studies, dam-height specifications, and volumetric assessments that give both parties a neutral technical basis for negotiation. …
