Tamil Nadu's Assembly has unanimously opposed Karnataka's ₹9,000 crore Mekedatu dam project on the Cauvery River. Chief Minister C Joseph Vijay moved a resolution urging the Union government to deny all clearances. The state argues the Cauvery basin is already fully allocated, citing tribunal and Supreme Court observations, and that Karnataka's unilateral move disregards existing water awards and basin state concurrence. Protecting water rights is a shared duty.
