US Appeals Court Says Decision to Free Mahmoud Khalil Lacked Jurisdiction, Opens Door to Rearrest

A US federal appeals court ruled on Thursday that a lower court judge lacked the authority to order the release of a prominent anti-Israel activist who helped stage riotous demonstrations on New York City college campuses.

Mahmoud Khalil, an Algerian citizen born in a Palestinian refugee camp in Syria, was detained by the Trump administration in March after federal agents arrested him at his Manhattan apartment for what the Department of Homeland Security described as “activities aligned to Hamas, a designated terrorist organization.” The State Department also alleged that Khalil was supporting Hamas and argued his residing in the US posed “serious adverse foreign policy consequences.”

Immigration officials moved Khalil to New Jersey, leading his case to be transferred there to US District Judge Michael Farbiarz.

Khalil was held without charge for more than 100 days at a facility in Louisiana administered by US Immigration and Customs Enforcement, until Farbiarz ordered his release in June, ruling that the government failed to prove he posed a threat and suggesting the detention may have violated his First Amendment rights.

On Thursday, however, a three-judge panel of the Philadelphia-based 3rd US Circuit Court of Appeals ruled 2-1 that the lower court lacked “subject-matter jurisdiction” under federal immigration law to halt the Trump administration’s effort to deport Khalil.

According to the appeals court, the district court that considered his lawsuit was not the proper forum to address Khalil’s claims, which should have been heard through an appeal of a removal order from an immigration judge in accordance with the Immigration and Nationality Act (INA).

The ruling stressed that Khalil lacks legal standing to challenge the government’s decision to deport him before his case has been adjudicated in immigration court, adding that the INA does not allow for a petition to review (PFR) the case at the federal level at this time.

“The scheme Congress enacted governing immigration proceedings provides Khalil a meaningful forum in which to raise his claims later on — in a petition for review of a final order of removal,” an opinion issued by the majority says. “That scheme ensures that petitioners get just one bite at the apple — not zero, or two. But it also means that some petitioners, like Khalil, will have to wait to seek relief for allegedly unlawful government or conduct.”

It added, “Because Khalil raises legal questions that a PFR court can meaningfully review later on, the INA bars him from attacking his detention and removal in a habeas petition.”

In a statement, Khalil was defiant even as he faces the possibility of being again detained.

“The door may have been opened for potential re-detainment down the line, but it has not closed our commitment to Palestine and to justice and accountability,” he said. “I will continue to fight, through every legal avenue and with every ounce of determination, until my rights, and the rights of others like me, are fully protected.”

Additionally, his lawyers, provided by the American Civil Liberties Union (ACLU), vowed to exhaust “every available avenue,” which may include a petition for his case to be decided by the US Supreme Court.

Speaking to Fox News, the Trump administration commended the decision, saying, “Mahmoud Khalil was given the privilege of coming to America to study on a student visa he obtained by fraud and misrepresentation. As we have always maintained, the executive branch has the lawful authority to take actions that will protect the public and to ensure the integrity of our immigration system.”

Beyond Khalil’s alleged pro-Hamas activities, the US government has maintained that its action was warranted by his lying to obtain a green card. In court documents it charged that Khalil did not disclose that he had interned for the United Nations Relief and Works Agency (UNRWA), a group that was found multiple times to have been breached by Hamas members, and also concealed key details about another position he held at the British embassy in Beirut, Lebanon. Khalil, the government added, also did not inform immigration officials about his leadership role in the notorious “Columbia University Apartheid Divest” (CUAD) group.

As previously reported by The Algemeiner, CUAD perpetrated illegal building occupations and severe infrastructure sabotage while Khalil participated in a graduate program at Columbia University in the months after the Hamas-led Oct. 7, 2023, massacre across southern Israel. The acts stunned Columbia’s campus, prompting fears of imminent revolutionary-style violence on campus even as Jewish students and faculty received antisemitic hate mail and death threats.

The Department of Homeland Security initially arrested Khalil while acting on an executive order issued by President Donald Trump which called for the deportation of foreign nationals who cause antisemitic hate incidents. A major provision of the order calls for the deportation of extremist “alien” student activists, whose alleged support for terrorist organizations, intellectual and material, such as Hamas supposedly contributed to fostering antisemitism, violence, and property destruction on college campuses.

Khalil has refused to condemn Hamas and even once denied that antisemitism at Columbia University required a policy response from school officials.

“I would say there is manufactured hysteria about antisemitism at Columbia because of the protests,” Khalil told Ezra Klein in an interview with The New York Times last year. “There are incidents here and there. But it’s not like antisemitism is happening at Columbia because of the Palestine movement … This is why I always push back. I have a strong belief that antisemitism and anti-Palestinian racism rise together because the same groups are perpetrating that in different ways.”

Khalil then went on to assert some of the very claims prompting accusations of antisemitism in the anti-Israel movement, accusing the Jewish state of “genocide” while arguing that the accusation is aimed at making pro-Israel supporters “uncomfortable” and defending the terrorist-led Palestinian intifadas.

“I don’t want to sanitize history,” Khalil continued. “Like I told you, the second intifada involved violent acts, but overwhelmingly, they were peaceful.”

Over 1,000 Israelis were killed in the early 2000s during the second intifada, when Palestinian terrorists ramped up violence targeting Israelis that included suicide bombings, shootings, and stabbings.

As previously reported by The Algemeiner, pro-Hamas activists at Columbia produced several indelible examples of campus antisemitism, including a student who proclaimed that Zionist Jews deserve to be murdered and are lucky he is not doing so himself, brutal gang-assaults on Jewish students, and administrative officials who, outraged at the notion that Jews organized to resist anti-Zionism, participated in a group chat in which each member took turns sharing antisemitic tropes that described Jews as privileged and grafting.

CUAD was among the most strident pro-Hamas organizations on campus and once promoted itself by distributing literature which called on students to join Hamas’s movement to destroy Israel and America.

“This booklet is part of a coordinated and intentional effort to uphold the principles of the thawabit and the Palestinian resistance movement overall by transmitting the words of the resistance directly,” said a pamphlet distributed by CUAD, a Students for Justice in Palestine (SJP) spinoff, to incoming freshmen. “This material aims to build popular support for the Palestinian war of national liberation, a war which is waged through armed struggle.”

Other sections of the pamphlet were explicitly Islamist, invoking the name of “Allah, the most gracious” and referring to Hamas as the “Islamic Resistance Movement.” Proclaiming, “Glory to Gaza that gave hope to the oppressed, that humiliated the ‘invincible’ Zionist army,” it said its purpose is to build an army of Muslims worldwide.

“We call upon the masses of our Arab and Islamic nations, its scholars, men, institutions, and active forces to come out in roaring crowds tomorrow,” it added, referring to a then-upcoming event. “We also renew our invitation to the free people and those with living consciences around the world to continue and escalate their global public movement, rejecting the occupation’s crimes, in solidarity with our people and their just cause and legitimate struggle.”

Columbia University denounced the group in 2025 as a part of a rollout of policies to combat antisemitism and unauthorized demonstrations which disrupted academic life.

In a statement issued in July, university president Claire Shipman said the institution will hire new coordinators to oversee complaints alleging civil rights violations; facilitate “deeper education on antisemitism” by creating new training programs for students, faculty, and staff; and adopt the International Holocaust Remembrance Alliance (IHRA) definition of antisemitism — a tool that advocates say is necessary for identifying what constitutes antisemitic conduct and speech.
