"Karnataka not releasing water to Tamil Nadu is a wrong decision which should not be allowed," Vasan told PTI over phone.
As compared to last year, Tamil Nadu has witnessed 50 per cent less rainfall this year and if the situation continued in the Delta region "there is a danger of drought," he said.
Karnataka should abide by the ruling of the Prime Minister, as head of the Cauvery River Authority, asking it to release 9,000 cusecs of water, which was endorsed by the Supreme Court, he added.
Vasan said the Prime Minister gave a patient hearing and assured "we will definitely discuss on the issue so that justice is done."
