1. Constitutional provision: Article 262(1), in Part V of the Constitution, empowers Parliament to provide by law for the adjudication of disputes or complaints concerning the use, distribution, or control of the waters of, or in, any inter-State river or river valley. Under Article 262(2), Parliament may by law exclude the jurisdiction of the Supreme Court or any other court in respect of such disputes. No separate Schedule governs this provision. 2. Statutory framework: The Inter-State River Water Disputes Act, 1956 provides for tribunals to adjudicate qualifying inter-State water disputes. The River Boards Act, 1956 concerns the establishment of river boards for the regulation and development of inter-State rivers. Union List Entry 56 concerns Union authority over the regulation and development of inter-State rivers and river valleys to the extent declared by Parliament to be expedient in the public interest. State List Entry 17 covers water supplies, irrigation and canals, subject to the relevant constitutional limitations. 3. Judicial and legal nuance: Article 262(2) enables Parliament to exclude court jurisdiction in relation to these disputes by legislation. Section 11 of the Inter-State River Water Disputes Act, 1956 restricts the jurisdiction of the Supreme Court and other courts in respect of disputes that may be referred to a tribunal under that Act. Constitutional questions concerning judicial review must nevertheless be assessed separately. Therefore, Parliament is the correct answer.
