Sarba Bala Mallick, 71, a resident of Dalimbari, 80 km from Guwahati, and her son Paritosh are marked as "doubtful voters" in Assam's voters' list. They are suspected to be Bangladeshis and facing trial at the foreigners' tribunal. Their names are not on the National Register of Citizens (NRC), whose final list will come out on Saturday.
