The direction was issued during the 54th CWMA meeting, which was attended by representatives of Cauvery basin states, including Karnataka and Tamil Nadu.
CWMA's decision to uphold Karnataka's release of 3,500 cusecs of Cauvery water to Tamil Nadu for the next 15 days drew opposition from farmer groups and Kannada film fraternity.
Reacting to a proposed meeting with Tamil Nadu Chief Minister C Joseph Vijay and his Karnataka counterpart D K Shivakumar over the dispute, the DMK spokesperson dismissed the effort as a "show off".
CM Shivakumar said he held detailed consultations with the advocate general, legal experts, and senior officials before deciding to strongly contest the CWRC order.
