The Union Cabinet on Friday made it clear that the Constitution, as framed by Dr BR Ambedkar, does not provide for a ‘creamy layer’ within the reservation system for Scheduled Castes (SCs) and Scheduled Tribes (Sts). Giving details, Union Information and Broadcasting Minister Ashwini Vaishnaw addressed the recent discussions triggered by a Supreme Court judgment on SC-ST reservations and said the NDA government is bound to follow the Constitution.
