The Delhi High Court on Thursday listed for hearing on September 9 Chief Minister Arvind Kejriwal's petition challenging the summonses issued to him by the Enforcement Directorate in connection with its probe into an excise policy-linked money laundering case. A bench headed by Justice Prathiba M Singh granted four more weeks to the AAP leader to file a rejoinder to the reply submitted by the ED. The senior counsel, appearing for Kejriwal, sought more time to file the rejoinder saying there are certain changes in the circumstances and they have not been given a proper legal interview, a plea for which is pending in the high court. "Let the rejoinder be filed in four weeks," the bench, also comprising Justice Amit Sharma, said. The counsel for the ED had earlier said the petition against the summonses was infructuous after Kejriwal's arrest by the agency on March 21 in the money laundering case following the high court's refusal to grant him interim protection from coercive action.
