As Centre runs of time to form a management board for sharing of Cauvery river water between three states, it has decided to ask for clarification on the matter from the Supreme Court, sources said. The move is expected to further delay a resolution of the contentious issue. Parties from Tamil Nadu, which stands to lose the most if the Board is not formed, says the Centre's delay is an attempt to score political points in Karnataka, where assembly elections will be held in May.
