BENGALURU: Accusing the Siddaramaiah-led Congress government of “failure” on the Cauvery issue after the Supreme Court today refused to interfere in orders to release water to Tamil Nadu, former chief ministers B S Yediyurappa and Basavaraj Bommai on Thursday urged it to file a review petition before the apex court.

The BJP leaders’ attack on the state government came after the Supreme Court today refused to interfere with orders of the Cauvery Water Management Authority (CWMA) and Cauvery Water Regulation Committee (CWRC), directing Karnataka to release 5,000 cusecs of water to Tamil Nadu.

Karnataka has been maintaining that it is not in a position to release water, taking into account its own need for drinking water and irrigation for standing crops in the Cauvery basin areas, as there has been water scarcity due to deficit monsoon rains.

“Based on the statistics we (Karnataka) provide, the Supreme Court gives its order. Law and Water Resources departments have completely failed in putting forward the argument effectively. Looking at today’s SC order, it proves that the government had gone to the court without doing proper homework, and has failed to provide proper records,” Yediyurappa said.

Speaking to reporters following the SC order, he said the state government has to speak to Tamil Nadu, where Congress’s ally DMK is in power, instead of “unnecessarily” trying to pull the central government into the issue.
