The Supreme Court on Monday granted Three weeks to the Centre for notifying the constitution of a tribunal to hear the water dispute between Goa and Karnataka on the construction of Kalasa Banduri project across the Mandovi river by the latter.A Bench of Justices Mukundakam Sharma and A R Dave told Additional Solicitor General (ASG) Haren Rawal that if steps were not taken for notifying the tribunal it would be forced to pass appropriate orders. The Centre had earlier told the apex court that it would constitute the tribunal but today when the matter came up for hearing it again sought three weeks forcing the apex court to pass the direction. Goa, in its suit filed through counsel A Subhashini, has contended the project contemplated by Karnataka in the inter-state river of Mandovi involved diversion of water outside the basin, which was not permissible. Karnataka has, however, rebutted the argument claiming that the proposed diversion of water was within permissible limit as estimated by Central Water Commission.
