Booth-level officers are contacting voters about spelling discrepancies in relatives' names on the draft electoral roll, raising concerns about potential deletions from the final list. Voters are being asked to provide documentation, such as PAN cards or passports, to prove relationships and correct spellings. While BLOs aim to resolve these issues, they cannot guarantee hearings will be avoided. The final electoral roll is set to be published on February 14, with specific requirements for voters whose relatives were not on the 2002 list.
