The Supreme Court of India has directed the Union Government to constitute an Inter-State River Water Disputes Tribunal within one month to resolve the Pennaiyar river water dispute between Tamil Nadu and Karnataka.
The direction followed a suit filed by Tamil Nadu under Article 131 of the Constitution of India, which gives the Supreme Court original jurisdiction in inter-State disputes. The matter falls under the Inter-State River Water Disputes Act, 1956, providing a legal mechanism for adjudication of river water sharing conflicts.
APSC Relevance:
APSC repeatedly asks questions on interstate river disputes, Article 131, and tribunal mechanisms under Indian Polity, making this topic highly important for examination preparation.
