Source reports published 20 Oct 2026, 6:52 am – 9:46 am AEST

Mahmoud Khalil, a Columbia University activist detained for pro-Palestinian demonstrations, is seeking a Supreme Court review of his deportation case. The court is being asked to determine if federal judges can review the legality of his detention before immigration court proceedings conclude.

What happened

• Mahmoud Khalil, a lawful permanent U.S. resident, is appealing a 3rd U.S. Circuit Court of Appeals ruling that prevented federal judges from reviewing the legality of his immigration detention.
• Khalil was detained by immigration authorities following his participation in pro-Palestinian demonstrations at Columbia University in 2024.
• The U.S. Department of Homeland Security argued his presence posed a threat to U.S. foreign policy.
• Following a federal judge’s order, Khalil was released after finding the government’s actions unconstitutional.
• The Supreme Court is being asked to decide if Khalil can challenge his detention in federal court before immigration court proceedings are complete.
• The U.S. government has requested the court to overturn a previous ruling regarding Badar Khan Suri, a Georgetown University scholar, highlighting potential conflicts between appeals court decisions and increasing the likelihood of the Supreme Court’s intervention.
