What the Khalil and Suri detention appeals ask the justices to decide
The piece explains the cases of Mahmoud Khalil and Badar Khan Suri, two noncitizen academics detained and targeted for removal over their support for Palestine. The government has asked the Supreme Court to resolve whether federal district courts may hear their detention challenges or whether immigration law blocks those suits. Both men have been released, but the jurisdictional dispute remains before the justices.
Badar Khan Suri, an Indian citizen and Georgetown postdoctoral fellow, was arrested in March 2025 near his Virginia home by masked DHS officers who cited his social media. The State Department concluded that alleged Hamas ties and advocacy conflicted with U.S. foreign-policy interests. A district court blocked deportation and later ordered bail; the Fourth Circuit upheld that ruling in July 2026.
Mahmoud Khalil, an Algerian citizen born in a Syrian Palestinian refugee camp and a 2024 lawful permanent resident, is the related case. Both men are now free, but the government asks the Supreme Court to decide whether federal trial courts can review their detention or whether immigration law sends such claims to appellate courts.
The justices’ eventual ruling could affect how quickly noncitizens in immigration detention can challenge removal-related detention in federal court. If appellate courts become the main forum, detainees may face different timelines and procedural hurdles, while immigration agencies could see changes in litigation volume. Universities, international students and scholars, and advocacy groups may also adjust how they respond to detention and speech-related enforcement, depending on how broadly the court defines the jurisdictional limits.
