Supreme Court Directs Centre to Constitute Tribunal for Pennaiyar River Water Dispute

The Supreme Court of India has directed the Central government to constitute a tribunal within one month to adjudicate the long-standing water-sharing dispute between Tamil Nadu and Karnataka over the Pennaiyar River. The Bench, led by Justice Vikram Nath, invoked Section 5 of the Inter-State River Water Disputes Act of 1956. Tamil Nadu had approached the court in 2018, challenging Karnataka's construction of dams and diversion structures, arguing that inter-state river water is a national asset and no single state can claim exclusive ownership. The court emphasized the need for a formal adjudicatory body.
