Case Overview

• Parties: The Chief Secretary to Government of Kerala (appellant) and Tamil Nadu Water Resources Organization (respondent).
• Issue: Whether the National Green Tribunal, Southern Zone, Chennai has jurisdiction to entertain a suo motu notice concerning an inter‑state water dispute, given Article 262 of the Constitution and Sections 6(A) & 11 of the Inter‑State River Water Disputes Act, 1956.
• Submissions: Appellant counsel (Jaideep Gupta) argued NGT lacks jurisdiction; cited constitutional and statutory provisions. Respondent counsel (G. Umapathy) represented Tamil Nadu.

• The State of Tamil Nadu may also raise objections.
• Any adverse order of the NGT can be challenged further in this Court.
• The appeals (Civil Appeal Nos. 4613‑4615/2026) are disposed of as per the signed order; any pending applications are also ordered to stand disposed.
