Tamil Nadu mulls Supreme Court plea for expanded Cauvery Authority powers

Tamil Nadu is preparing potential legal grounds to petition the Supreme Court for an expansion of the Cauvery Water Management Authority's mandate and enforcement capabilities. The state government believes the existing framework limits the authority's ability to effectively manage water distribution across the Cauvery basin, which spans Tamil Nadu, Karnataka, Kerala, and Puducherry.

State authorities have identified the Bhakra Beas Management Board as a model that could be adapted for the Cauvery. The BBMB operates with broader powers to coordinate water management, resolve disputes, and implement decisions across state boundaries in the Sutlej and Beas river systems. Tamil Nadu argues a similar structure would strengthen the Cauvery Authority's governance capacity and ensure more effective regulation of water allocation and usage.

The proposal reflects ongoing tensions over Cauvery water sharing, particularly between Tamil Nadu and Karnataka. The state government contends that enhanced powers for the management authority would provide a more robust institutional mechanism to enforce Supreme Court directives and mediate disputes, potentially reducing litigation and ensuring predictable water availability for agriculture and domestic consumption.

Official confirmation of the court petition timeline and detailed proposals remains pending as the state government continues consultations with legal advisors and water resources departments. The move underscores the persistent challenges in inter-state river water management and the search for institutional solutions that can command cross-state cooperation.
