The Election Commission of India (ECI) has flagged more than 1.36 crore voters in West Bengal through progeny mapping following the first phase of the Special Intensive Revision (SIR) of the electoral roll. Chief Electoral Officer Manoj Kumar Agarwal said the claims and objections period will continue until January 15. "More than 50% of the mismatch during progeny mapping is the father’s name mismatch. There can be cases where names have been legally changed, but software does not identify this, a proper verification process will solve this issue," Mr. Agarwal explained after publishing the draft electoral roll on the ECI website. He assured that all genuine mismatches will be resolved easily, while other cases will get hearing notices. Booth Level Officers (BLO) hold voter data and will verify these mismatches and discrepancies. Progeny mapping allows voters not present in the 2002 electoral roll to establish family links such as father, mother, or grandparents to join the list. Voters with names in the 2002 rolls fall under self mapping. Overall, 1.62 crore discrepancy cases were found in categories like father name mismatch and unrealistic parentage age differences, but some voters had multiple discrepancies. If voters disagree with flagged issues, they can file complaints with the District Magistrate, and if dissatisfied with the outcome, they can appeal to the CEO’s office, officials said.
