The resolution, moved by Chief Minister J Jayalalithaa, also urged the Centre not to grant clearance to Kerala and Karnataka to take up any project in the Cauvery basin till the Cauvery Management Board and Cauvery Water Regulation Committee came into force and court cases in this regard were settled.
Following reports in 2012 about Kerala's attempts to build a dam on the Siruvani river as part of the project, the Chief Minister had taken it up with the then Prime Minister Manmohan Singh, urging that Kerala be advised not to proceed with any project till the 2007 final award of the Cauvery Tribunal was published in a Central gazette and cases filed by the respective states were settled.
Therefore, the Cauvery River Water Tribunal, while delivering its final verdict in 2007 on river water sharing, had included the Siruvani and Bhavani basins also to calculate the quantum of sharing, it said.
The state government was then in constant communication with the Centre, arguing against granting any technical approval to Kerala on the issue, it said.

However, the EAC had recommended to the Environment Ministry in August this year that Kerala be granted approval for conducting the EIA.
"This is in contradiction to the March 2013 letter of the Central Water Resources Ministry. It is regrettable that the EAC had granted approval in haste," it said.
used the word "instead of" for "in spite of" in an observation that read: "The EAC took note of no responses from the Tamil Nadu state instead of several letters sent from the Government of Kerala and MoEF and CC to the Government of Tamil Nadu..." and this showed the EAC's haste, it added.
The resolution was welcomed and supported by the DMK, whose deputy leader Durai Murugan spoke on it, the Congress, the IUML and the AIADMK allies -- Manithaneya Jananayaka Katchi, Kongu Ilaignar Peravai and Mukkulathor Pulippadai.
