Clearing the clouds over the confusions on whether the Centre had approved the premature release of the 11 convicts in Bilkis Bano case, the Gujarat Government yesterday told the Supreme Court that they had the prior approval from the Union Home Ministry. The convicts accused of brutal gangrape of Bilkis Bano and killing of her family members during the 2002 post-Godhra pogroms walked free on this independence day inviting severe criticism from different quarters.
