There was a subdued optimism in the Philadelphia room where Mahmoud Khalil’s lawyers met this month that seemed almost brittle, like steam rising from a teacup right before it settles. Khalil’s legal future is once again uncertain after a three-judge panel of the U.S. Court of Appeals for the Third Circuit recently overturned the order that had set him free.
ICE agents detained Khalil, a Palestinian-American activist who assisted in organizing pro-Palestinian demonstrations at Columbia University, at his apartment in March 2025. Many found the justification—unnamed “foreign policy concerns” connected to his advocacy—to be especially unsettling. It was the kind of reasoning that had serious repercussions but provided little clarity.

After that, he was taken to a Louisiana prison, where he spent 104 days there, missing the birth of his son. That particular detail seemed to capture the human cost of bureaucratic action when it was revealed in court and then repeated in activist circles. After concluding that the legal justifications for his detention were probably unconstitutional, a federal judge in June ordered his release.
That reasoning was not directly contested in the recent appeals court ruling. The decision, which concentrated on jurisdiction instead, determined that his case had to be heard in immigration court rather than a federal district court in accordance with federal immigration law. In essence, the court told Khalil that he would have to wait his turn even though he might eventually bring up constitutional issues.
Homeland Security officials praised that technical reasoning, calling it a victory for the “rule of law.” However, it also made re-detention possible, which Khalil and his legal team are getting ready for. He is still free for the time being, but his legal situation is uncertain.
The road to activism for Khalil started long before Columbia. He was raised in the United States after being born in a refugee camp, where he had to manage two identities that frequently clashed. He became a well-known student organizer at Columbia during the 2024 Gaza encampment movement. His speeches were composed, thoughtful, and centered on human rights and international law. He was a strategist rather than a firebrand.
But the federal government had a different perspective. Although they provided no public proof, officials asserted that Khalil oversaw actions “aligned with Hamas.” Rather, they relied on a vague law that permits the deportation of foreign nationals whose views are said to jeopardize U.S. foreign policy objectives. Rarely applied, that law turned out to be crucial to the case.
Judge Michael Farbiarz stated in a lower court decision that Khalil had not only not demonstrated any indications of being a danger or flight risk, but he was also likely to be successful in contesting the constitutionality of his detention. Even though it has since been overturned, that opinion served as the moral and legal foundation for Khalil’s defense.
I recall stopping when I read the word “irreparable harm” in that ruling. I was struck by how frequently courts measure something that cannot be measured, such as a missed family moment or a life that is halted in the middle of a chapter.
The Center for Constitutional Rights and the American Civil Liberties Union have joined Khalil’s legal team. It is evident from their larger argument that this is about more than one man. It concerns the way the government responds to political dissent, particularly when it originates from a non-citizen.
Arianna Freeman, the dissenting appellate judge, contended that Khalil’s constitutional claims were urgent and should not be delayed. She was concerned that by ignoring those issues, the courts might leave illegal behavior unchecked.
Campuses, advocacy groups, and the legal community have all embraced Khalil. Despite his reluctance, he has come to represent the dangers that noncitizens who participate in protest face. Even people who are not familiar with his cause have expressed admiration for his composed manner during interviews and his emphasis on due process over rhetoric.
According to the government, Khalil lied on his green card application and his speeches are dangerous from a diplomatic standpoint. However, it is extremely challenging to disentangle these arguments from the political context in which they have been presented. His detention, according to critics, was retaliation disguised as regulation.
The personal cost has been high for Khalil. He was kept in solitary confinement for weeks, and he was once refused access to legal documents and books. Unfazed by the prospect of being arrested again, he has persisted in publicly supporting Palestinian rights since his release.
Legal experts are hopeful that this case may compel a reconsideration of the First Amendment’s protections for permanent residents, particularly those who participate in political activities that jeopardize U.S. foreign alliances. The long-simmering tension between immigration enforcement and free speech now has a human face.
Khalil’s case could be a turning point in the relationship between immigration law and political expression if it makes it to the Supreme Court. For the time being, the appeals process continues, along with the silent perseverance of a man who continues to maintain that peaceful protest has a place in American democracy in spite of surveillance, detention, and public scrutiny.
