A US appeals court overturned on July 21, 2026 a lower court ruling that had ordered the release of Columbia University activist Mohsen Mahdawi from immigration detention, reopening a legal battle that has drawn together questions of constitutional speech protections, immigration enforcement authority, and the geopolitical framing of campus protest.

The decision, issued by the US Court of Appeals for the Third Circuit (docket 25-2162), reverses a 2025 ruling by US District Judge Geoffrey Crawford. Crawford had ordered Mahdawi released after finding that he "enjoyed the same free speech rights as US citizens" and accused the Trump administration of causing "great harm" to someone who had committed no crime (Al Jazeera). The Third Circuit's opinion centered on jurisdictional questions surrounding habeas corpus and immigration proceedings, and noted that the case involves a master's program at Columbia University (Third Circuit opinion).

Mahdawi, a lawful permanent resident born in the occupied West Bank, describes himself as a "stateless Palestinian refugee from the occupied West Bank." He was arrested in April 2025 after attending what he believed was an interview related to his US citizenship application. He was detained for two weeks and charged with no crime (Al Jazeera).

The legal trajectory since his arrest has been turbulent. In February 2026, immigration judge Nina Froes blocked the Trump administration's deportation attempt, ruling that the government "failed to meet its burden of proof." Froes was subsequently fired by the Trump administration. Then in May 2026, the Board of Immigration Appeals reinstated deportation proceedings against Mahdawi, setting the stage for the Third Circuit's intervention (Al Jazeera).

The administration's legal posture rests on a specific statutory framework. It argues that Secretary of State Marco Rubio possesses authority under federal immigration law to seek the deportation of non-citizens whose presence could have "adverse foreign policy consequences" for the United States. That provision has become a central instrument in the administration's broader effort to remove non-citizen activists linked to campus protest movements, though the Mahdawi case is the one now before the appellate courts (Al Jazeera).

The Third Circuit's ruling focuses on jurisdictional architecture: whether the federal district courts, through habeas corpus, can properly review detention and release in immigration matters of this nature, or whether those questions belong exclusively within the immigration court system and the appellate bodies that oversee it. By overturning Crawford's order, the appellate court effectively narrows the avenue through which Mahdawi's attorneys secured his release, redirecting the dispute back into the immigration adjudication pipeline.

Several threads converge here in ways that matter for practitioners tracking executive-branch immigration enforcement. The Froes firing, the Board of Immigration Appeals reversal, and now the Third Circuit's jurisdictional ruling together form a sequence in which each institutional layer has been either bypassed or overridden. The removal of an immigration judge who ruled against the government mid-proceeding is particularly notable; it raises structural questions about the independence of immigration adjudicators within the Executive Office for Immigration Review.

The statutory provision the government invokes, which ties deportability to a Secretary of State's determination of adverse foreign policy consequences, has historically functioned as a narrow tool. Its application to campus activists who are lawful permanent residents, rather than visa holders subject to consular inadmissibility standards, pushes the provision into comparatively untested territory. The question of whether free speech protections extend to lawful permanent residents in the same measure as to citizens, as Judge Crawford asserted, remains contested at the appellate level; the Third Circuit did not rule on the merits of that constitutional claim but instead reversed on jurisdictional grounds.

For Mahdawi personally, the practical consequence is renewed exposure to deportation proceedings in an immigration court system that has already produced one ruling against him at the appellate level. His self-identification as a stateless Palestinian refugee complicates removal logistics even if deportation is ultimately ordered, since statelessness can impede the identification of a receiving state willing to accept the individual.

The broader context here is an administration that has leaned heavily on the intersection of immigration law and foreign policy authority to pursue removals of non-citizen activists, testing the boundaries between the plenary power doctrine traditionally governing immigration matters and constitutional protections that may constrain executive discretion. The Third Circuit's opinion, by focusing on jurisdiction rather than constitutional merits, leaves the core free speech question unresolved at the appellate level. Whether the Supreme Court will eventually weigh in on the substantive constitutional claims, or whether the case will be litigated entirely within the immigration and habeas frameworks, is a question that turns on the next procedural moves by Mahdawi's legal team and the government's litigation strategy.
