In 1997, a tribunal in Diphu, Karbi Anglong, declared Sabitri Dey and her family foreigners. Nobody from the family appeared before it. The Gauhati High Court affirmed the finding in 2020, adding that Sabitri Dey had come to the court too late. On July 13, 2026, the Supreme Court set aside both orders in Sabitri Dey @ Swasthi Dey and Others v. Union of India and Others. Her case was one among 28, all of them decided by Foreigners Tribunals (or the Illegal Migrants [Determination] Tribunals) in Assam without the person concerned actually being heard.
