Supreme Court Mandates Tribunal to Adjudicate Pennaiyar River Water Dispute
In a decisive move to resolve a protracted inter-state conflict, the Supreme Court of India has directed the Union government to constitute a tribunal within one month to adjudicate the water-sharing dispute between Tamil Nadu and Karnataka over the Pennaiyar River . This order, issued by a Bench comprising Justices Vikram Nath and N V Anjaria , marks a critical judicial intervention to break the years-long deadlock over the river's waters.
Court's Directive to the Central Government
The Supreme Court Bench explicitly instructed the Centre to issue the necessary notification to set up the inter-state water disputes tribunal under the relevant statutory framework. Observing no justification for further delays, the court emphasized the urgency of activating the formal legal mechanism to address the grievances of both states, setting a clear one-month deadline for this action.
Background of the Long-Standing Dispute
The legal confrontation originated from a petition filed by the Tamil Nadu government in 2018 . Tamil Nadu challenged Karnataka's construction of check dams and diversion structures on the Pennaiyar River (also known as Pinakini), arguing that these upstream projects severely curtail water flow into its northern districts. The state contends that this reduction adversely affects agricultural irrigation and drinking water supplies , especially during dry seasons, violating its rights as a lower riparian state.
Legal Principles and Constitutional Dimensions
During proceedings, Tamil Nadu argued that the water of an inter-state river is a national asset , and no state can exercise unilateral control over it. The state invoked the Constitutional scheme and the Inter-State River Water Disputes Act (ISRWD Act), 1956 , asserting that Karnataka's actions required adjudication by a specialized tribunal. The Supreme Court upheld this view, affirming that a tribunal is the appropriate forum to examine the technical, hydrological, and equitable aspects of such a complex dispute.
Significance of the Tribunal's Formation
The court's order is poised to reinvigorate the formal resolution process for the Pennaiyar dispute, which has seen little progress despite prolonged negotiations. Once established, the tribunal will undertake a comprehensive exercise: examining legal claims, scrutinizing hydrological data , and ultimately determining an equitable water-sharing arrangement . This directive underscores the judiciary's role in ensuring the timely institutional resolution of inter-state water conflicts, which are vital for regional harmony and sustainable resource management.
