Kolkata, Oct. 6 -- The Election Commission of India's (ECI's) special drive to enrol left-out electors, whose names were deleted during the special intensive revision (SIR) in West Bengal, will consist of three categories-voters with logical discrepancies, ASDD (absent, shifted, dead and duplicate) voter and those who could not be mapped, officials aware of the matter said on Monday. "We have been issued three categories to register the names of left out voters (names which were deleted during SIR) - voters with logical discrepancies, ASDD voters and those who couldn't be mapped. The first training session for the special drive was held in some districts, including Murshidabad on Monday," said a Booth Level Officer (BLO) who attended the training. A senior official aware of the developments said that BLOs will compare the current electoral roll with the pre-SIR roll and identify the electors whose names have been deleted. "The BLOs will visit house-to-house of these voters to identify their present status and facilitate enrolment through Form-6. The list will be shared with the Booth Level Agents of the political parties. The BLOs will also share the list, the filled-up Form-6 and their filed verification report with the Electoral Registration Officers, who in turn will take the call," said the senior official. Confusion, however, looms on the fate of the 2.2 million voters who have approached the Supreme Court-mandated Appellate Tribunals after their names were deleted. "There is still no clarity on whether these 2.2 million voters whose cases are now being heard in the Appellate Tribunals will be included in the special drive. We were only told in the training that it will be decided by EC," said another BLO. Meanwhile, a section of BLOs sent a letter to the state chief election officer (CEO) requesting security for themselves, saying that they may be targeted during door-to-door visits in sensitive areas. West Bengal CEO Neelam Meena didn't respond to calls....
