The court ruling that freed Mahmoud Khalil is gone. On January 15, 2026, a divided panel of the U.S. Court of Appeals for the Third Circuit vacated the district court judgment that ordered his release from immigration detention last June and directed that his federal lawsuit be dismissed outright. The panel did not decide whether the government violated Khalil's First Amendment rights by detaining him over his campus activism. It decided something narrower and, for him, more dangerous: that the court which protected him never had jurisdiction to do it.
The 2–1 majority held that under the Immigration and Nationality Act's review scheme, Khalil's claims belong in the immigration system first — before an immigration judge, then the Board of Immigration Appeals, and only afterward in a federal appeals court reviewing a final removal order. On that logic, U.S. District Judge Michael Farbiarz was the wrong forum when he ordered the Department of Homeland Security to release Khalil from Louisiana detention in June 2025, and the release order cannot stand.
Judge Arianna Freeman dissented, and her warning is the heart of the case: channeling everything into the removal pipeline means a person alleging that his detention is punishment for protected speech gets no meaningful court review while the detention is happening. The review the majority promises arrives at the end of the administrative road, which can be years away. For someone the government wants back in a cell now, a remedy later is barely a remedy at all.
Where this leaves Khalil
The ruling does not take immediate effect, and it does not itself order Khalil re-arrested. His lawyers say they will appeal — rehearing by the full Third Circuit or a petition to the Supreme Court — and those steps buy time. But the practical stakes are plain: the legal shield that has kept him free since June 2025 has been pulled away, and Reuters reports the decision opens the door to renewed detention.
Khalil, a Columbia graduate and the most prominent figure to emerge from the university's Gaza solidarity protests, was arrested by immigration agents on March 8, 2025, in the lobby of his own university residence in Manhattan — the first arrest of the administration's campaign against pro-Palestinian campus activists. He spent more than three months in Louisiana detention, missing the birth of his son. He has never been charged with a crime. Federal officials have accused him of leading activities "aligned to Hamas" while presenting no public evidence, and in September an immigration judge ordered him removed to Algeria or Syria based on claims that he omitted information from his green-card application — an order his lawyers are appealing.
DHS spokesperson Tricia McLaughlin called the Third Circuit's decision a "vindication of the rule of law" and urged Khalil to "self-deport." The rule-of-law framing sits awkwardly beside the record: a legal permanent resident seized over his politics, held without charge, and now told the courthouse doors don't open until the deportation machinery has finished its work.
The ruling will echo beyond one man. Every other student and scholar detained over Gaza-war speech — Öztürk, Mahdawi, Suri, and those who come next — relied on the same habeas pathway the Third Circuit has now narrowed. That is the precedent the government came for, and the one it got.
