The Supreme Court on Friday issued a showcause notice to Genetic Engineering Approval Committee (GEAC) to explain as to why contempt proceedings should not be initiated against them for approving field trials of new genetically modified (GM) crops. The apex court gave four weeks time to GEAC to respond. On September 13, petitioners Aruna Rodrigues and PV Satheesh had filed a petition against three members of GEAC-chairman BS Parsheera, co-chairman, CD Mayee and member-secretary Ranjini Warrier for deliberately disobeying the explicit orders of the Supreme Court passed on September 22, 2006, May 8, 2007 and August 1, 2007.
