The Supreme Court on Monday set aside Gauhati High Court judgments that had upheld Foreigners Tribunal declarations of 27 individuals as foreigners and remanded the matters for fresh adjudication. The bench of Justices Vikram Nath and Sandeep Mehta cited the high constitutional significance of citizenship status. The petitioners had challenged the ex parte tribunal orders after 23 years and did not appear before the High Court despite notices.
