The Supreme Court directed the Centre to form a tribunal to adjudicate the dispute between Tamil Nadu and Karnataka over the sharing of Pennaiyar river water. A Bench headed by Justice Vikram Nath directed the Centre to issue a notification to constitute the inter-State water disputes tribunal within a month, under Section 5 of the Inter-State River Water Disputes Act of 1956. In 2018, Tamil Nadu moved the Supreme Court against Karnataka over its work on dams and diversion structures on the river. Tamil Nadu argued that the flowing of water of an inter-State river was a national asset and no single State could claim exclusive ownership of its water. An 1892 agreement over the river water was “valid and binding” on the party States.

Background

The issue of inter-state river water disputes in India is a long-standing one, rooted in the country's geography and federal structure. India has numerous rivers that flow through multiple states, leading to conflicts over water sharing. The constitutional framework addresses this through Article 262, which allows Parliament to legislate on inter-state river water disputes. This led to the enactment of the Inter-State River Water Disputes Act of 1956. The Inter-State River Water Disputes Act of 1956 provides a mechanism for the adjudication of disputes relating to inter-state rivers and river valleys. Under this act, if a state government requests the Union Government to refer a water dispute to a tribunal, the Union Government is required to set up a tribunal after trying to resolve the dispute through negotiations. The tribunal's decision is final and binding on the parties to the dispute. However, the effectiveness of this mechanism has been questioned due to delays in the constitution of tribunals and the implementation of their awards. Several tribunals have been constituted under the Inter-State River Water Disputes Act of 1956 to resolve disputes over rivers like the Cauvery, Krishna, and Godavari. These tribunals have faced challenges such as delays in data collection, disagreements among states on water sharing formulas, and legal challenges to their awards. The current dispute over the Pennaiyar river highlights the continuing need for effective mechanisms to resolve inter-state water disputes in a fair and timely manner.

Latest Developments

In recent years, there has been a growing emphasis on resolving inter-state water disputes through negotiation and mediation, rather than relying solely on tribunals. The Union Government has been actively promoting dialogue between states to reach amicable solutions. The Jal Shakti Ministry has played a key role in facilitating these discussions. There is also a move towards establishing a permanent tribunal to deal with inter-state river water disputes. This would help in speeding up the adjudication process and avoiding delays in the constitution of tribunals on an ad-hoc basis. The proposed permanent tribunal would have specialized benches to deal with different types of disputes. Looking ahead, the focus is likely to be on promoting sustainable water management practices and ensuring equitable access to water resources for all states. This will require greater cooperation and coordination among states, as well as the adoption of innovative technologies for water conservation and efficient irrigation. The success of these efforts will be crucial for ensuring water security and preventing future conflicts over water sharing.
