The Centre cannot continue to evade its legal obligation to create a mechanism to implement the Supreme Court's final verdict in the Cauvery dispute. This was the broad message conveyed by the court on Monday when it admonished the government for failing to frame a scheme within the six-week time limit given earlier. For the Centre, it was embarrassing to be asked to demonstrate its bona fides by submitting a draft scheme for the court's consideration by May 3. The court's frustration was evident, as the Bench headed by the Chief Justice of India was surprised and disappointed that the Centre had not put a scheme in place or sought an early clarification. It is obvious that a decree on the sharing of water requires a mechanism to give effect to it. It is an evasion of responsibility on the Centre's part to set off a round of litigation just to determine the nature of such a mechanism. At the same time, it is easy to understand the reluctance of the Bharatiya Janata Party-led government at the Centre. It clearly fears that framing a scheme may adversely affect its prospects in Karnataka, which goes to the polls next month. In the conflict between duty and electoral considerations, the BJP has chosen the latter. It is a matter of satisfaction that the apex court has indicated that it will pass a binding order soon. The Centre should redeem itself by complying with the latest order.
