The Supreme Court on Monday set aside 27 Gauhati High Court judgments that had upheld Foreigners Tribunal orders declaring individuals as foreigners, ruling that questions of citizenship must be determined through a “fair, lawful and reasonable” process. Calling citizenship disputes issues of “high constitutional and legal significance”, a Bench of Justices Vikram Nath and Sandeep Mehta remanded all 27 cases to the respective Foreigners Tribunals for fresh adjudication.
