Tamil Nadu Chief Minister C. Joseph Vijay wrote to PM Narendra Modi on July 28, 2026, demanding that no statutory approval be granted to Karnataka's Mekedatu project.
Vijay requested the withdrawal of a July 27 Rajya Sabha reply by Union Minister Raj Bhushan Choudhary, which claimed Karnataka does not need lower riparian state consent for the project.
The CM cited the 2018 Supreme Court judgment and the Cauvery Water Disputes Tribunal Award, arguing that any project affecting regulated flow requires mandatory scrutiny and inter-state agreement.
