79-year-old Saeed Ali, a farmer from Kalgachia in Assam's Barpeta district, has been a worried man since 1997, when he was declared a doubtful voter. Unable to vote and excluded from the National Register of Citizens (NRC), Mr Ali is waiting for trial to begin at a foreigners' tribunal, which will provide his only chance to prove his citizenship. Barely literate, Mr Ali, however, has no awareness about his constitutional rights.
