आंतरराज्यीय नद्या व नद्या खोरे विवादांबाबत खालीलपैकी कोणते विधान चुकीचे आहे ?

The correct answer is Option B (Parliament, by law, cannot restrict the jurisdiction of Supreme Court as regards inter state river or river valley water disputes.).

Key Points:
• Article 262 Text & Scope: Article 262(1) empowers Parliament to provide by law for the adjudication of any dispute or complaint regarding the use, distribution, or control of waters of an inter-State river or river valley.
• Ouster of Judicial Jurisdiction: Under Article 262(2), Parliament may by law provide that *neither the Supreme Court nor any other court shall exercise jurisdiction* in respect of any such dispute or complaint.
• Statutory Execution: Under this constitutional mandate, Parliament enacted the Inter-State River Water Disputes Act, 1956, whose Section 11 explicitly bars the jurisdiction of the Supreme Court and all other courts over river water disputes referred to a tribunal.
• Analysis of Option (2): Statement (2) claims that Parliament *cannot* restrict the Supreme Court's jurisdiction, which is constitutionally false, making statement (2) the incorrect statement.
• Krishna Tribunal: The Krishna Water Disputes Tribunal (KWDT) was established under this exact mechanism pursuant to Article 262.
• Key Takeaway: Under Article 262(2), Parliament can exclude the Supreme Court and all other courts from adjudicating inter-state river water disputes.
