The Supreme Court on Tuesday examined the Secret Ballot Voting method during a review of petitions requesting a comparison of votes cast on Electronic Voting Machines with paper slips from the Voter Verified Paper Audit Trail (VVPAT) system. During the hearing, the apex court pointed out the problems with the method. "We all know what happened when there were ballot papers...we have not forgotten," Justice Sanjiv Khanna told Prashant Bhushan, counsel for one of the petitioners, Association for Democratic Reforms.
