The Supreme Court said on Monday that it would ‘set aside’ the Special Intensive Revision (SIR) drive of electoral rolls in poll-bound Bihar if it finds any ‘illegality in methodology’ adopted by the Election Commission of India (ECI). Fixing October 7 as the final hearing of arguments, the top court also stated that it cannot give any ‘piecemeal opinion’ on the matter, and the final verdict would be applicable for pan-India SIR.
