he Supreme Court said today it will hear on April 16 a batch of pleas seeking cross-verification of the votes cast with Voter Verifiable Paper Audit Trail (VVPAT). The VVPAT is an independent vote verification system which enables an elector to see whether his vote was cast correctly. It generates a paper slip which can be viewed by the voter. It is kept in a sealed cover and can be opened in case of a dispute.
