New Delhi, July 29 -- The Supreme Court on Monday refused to interfere in the Punjab and Haryana high court's order directing Punjab to release additional 4,500 cusecs of water to Haryana. Dismissing the state's appeal against the May 6 order of the high court, a bench of justices Vikram Nath and Sandeep Mehta permitted the state to challenge the original order passed by the Bhakra Beas Management Board (BBMB) in April requiring the state to release 8,500 cusecs. Of this, the state had released 4,000 cusecs. While doing so, the top court held that the high court would consider the state's plea without being influenced by its earlier order. The bench noted that while the state had come up in challenge against the May 6 HC order, it failed to appeal against the BBMB order that formed the basis for the order under challenge. Further, on May 2, the Union home secretary had intervened and asked Punjab to release the additional water to Haryana as per BBMB's directive.P4...
