West Bengal's CEO has issued guidelines for handling 'unmapped' voters, primarily those aged 85 and above, sick, or disabled. These electors may be exempted from personal hearings, with verification conducted at their residences. The issue stems from data conversion errors in the 2002 electoral rolls. The CEO's office is seeking Election Commission approval for uploading relevant data to facilitate these exemptions, while district authorities are advised to hold hearing notices for affected individuals.
