The Karnataka Cabinet late on Sunday night decided to release Cauvery water to Tamil Nadu. The government, however, is yet to make an announcement about the decision, fearing a law and order problem in the Cauvery basin.The release is expected to commence in the wee hours of Monday from the Krishnarajasagar reservoir. The government has kept the information under wraps on the pretext that ‘‘the issue is sub-judice.’’ Information Minister Kagodu Thimmappa, emerging out of the Cabinet meeting, read out a prepared text: ‘‘Whatever submissions we have to make will be made before the Supreme Court by our advocates.’’The Mandya district administration has, however, ordered closure of all educational institutions on Monday and Tuesday as a precautionary measure. Heavy police bandobust has been made in the district.In the affidavit the state is filing before the SC on Monday, the government would offer an unconditional apology for its omissions and commissions and inform the Court about the state’s compliance to its orders.Law Minister D.B. Chandre Gowda and Advocate General A.N. Jayaram will leave for New Delhi on Monday, carrying the state’s affidavit along with them.Chief Minister S.M. Krishna, who flew in from Delhi this morning, was authorised by the Council of Ministers to take a final decision on the issue. However, the all-party meet turned out to be a damp squib with all Opposition parties, except the CPI, boycotting it.Krishna refused to give details of the meetings. At the meetings too, he spoke little and listened more. As a result, speculation did the rounds throughout the day.On Sunday, the state received advice from its counsel Fali S. Nariman, explaining the various legal options before the Government and the possible consequences of its actions on the Cauvery imbroglio.
