A senior poll official said domicile certificates submitted during Special Intensive Revision (SIR) hearings in West Bengal are not valid at present. The official said voters who already submitted domicile certificates may be summoned again for fresh hearings. The official said acceptable SIR documents include permanent address or residence certificates issued by the State, and domicile certificates do not qualify. The official said nearly 10,000 newly issued voter ID cards were returned because intended recipients were not found at the given addresses, and the cards will be resent after the final electoral rolls are published on February 14.
