Even as murmurs of SIMI role in the serial blasts persist, a Special Tribunal on Monday asked the Centre if it had any "fresh material" to "connect" the organisation to "bomb blasts, riots, destructive activities". "You say that SIMI is connected to bomb blasts, riots, destructive activities. Place specific material before me, you (Centre) cannot presume their involvement," said Justice Gita Mittal, the presiding officer of the Unlawful Activities Prevention Tribunal. "It is the right of a person to know by what activities he is being banned," observed the court. Mere mention for an "immediate curb or control" over SIMI in the notification is not enough, it added, "reasons have to be stated". Both SIMI and the Centre have been asked by the Tribunal to file detailed written submissions in the case. The Tribunal has to file its report in the Home Ministry on the legality of the notification by August 6, 2008. Counsel for SIMI Mobin Akhtar argued that "the Centre each time improves on its own previous orders for a ban".
