The poll panel, which maintained that Electronic Voting Machines (EVMs) cannot be tampered with, told the apex court that around 70,000 Voter Verified Paper Audit Trail (VVPATs) units would be required for the Gujarat polls scheduled later this year. It said that around 48,000 units were expected to be delivered by Bharat ElectronicsLtd (BEL) and Electronics Corporation of India Ltd (ECIL) by August 31 while another 25,500 such units would be delivered by September. “If the said consignment of VVPATs is delivered on time, the Election Commission expects to be able to conduct the elections to the Gujarat legislative assembly completely with the use of VVPATs,” the poll panel told the apex court in its affidavit.
