Case Note & Summary
The State of Tamil Nadu filed Original Suit No. 1 of 2018 under Article 131 of the Constitution of India against the State of Karnataka and the Union of India, seeking declarations and injunctions regarding the use of waters of the inter-State river Pennaiyar. Tamil Nadu alleged that Karnataka had undertaken various construction works, including check dams, diversion structures, and pumping schemes, on the Pennaiyar river and its tributaries, which violated the Madras-Mysore Agreement of 1892 and adversely affected the flow of water to Tamil Nadu, impacting agriculture and drinking water needs. The suit sought a declaration that Karnataka's unilateral actions were illegal, a permanent injunction restraining further construction, a direction to ensure natural flows, and a mandatory injunction directing the Union of India to take action. The Union of India, in its written statement, submitted that no request for appointment of an arbitrator under the 1892 Agreement or for setting up a Water Disputes Tribunal under the Inter-State River Water Disputes Act, 1956 (ISWD Act) had been received from either state. Karnataka, in its written statement, contended that the suit was not maintainable in view of Article 262 of the Constitution and Section 11 of the ISWD Act, 1956, which bar the jurisdiction of the Supreme Court in respect of water disputes that may be referred to a Tribunal. The Supreme Court, after hearing the parties, dismissed the suit as not maintainable, holding that the dispute clearly falls within the ambit of the ISWD Act, 1956, and that the jurisdiction of the Supreme Court under Article 131 is barred by Article 262 and Section 11 of the ISWD Act. The Court did not adjudicate on the merits of the dispute, leaving it open for the parties to seek recourse before the appropriate forum under the ISWD Act.
Headnote
A) Constitutional Law - Original Jurisdiction of Supreme Court - Article 131 - Inter-State Water Disputes - The Supreme Court held that a suit under Article 131 is not maintainable when the dispute relates to the use, distribution, or control of waters of an inter-State river, as Article 262 read with the Inter-State River Water Disputes Act, 1956, bars the jurisdiction of the Supreme Court and vests it exclusively in a Water Disputes Tribunal. (Paras 1-10) B) Water Law - Inter-State River Water Disputes Act, 1956 - Section 11 - Bar of Jurisdiction - The Court held that Section 11 of the ISWD Act, 1956, expressly bars the jurisdiction of the Supreme Court in respect of any water dispute that may be referred to a Tribunal under the Act, and therefore, the suit filed by Tamil Nadu against Karnataka and the Union of India is not maintainable. (Paras 3-10) C) Water Law - Madras-Mysore Agreement of 1892 - Inter-State River Pennaiyar - The Court noted that the dispute pertains to the construction of check dams, diversion structures, and pumping schemes by Karnataka on the Pennaiyar river and its tributaries, which allegedly violate the 1892 Agreement. However, the Court did not adjudicate on the merits as the suit was dismissed on maintainability grounds. (Paras 1-5)
