The lawyers for Mahmoud Khalil, a former Columbia University student targeted for deportation by the United States government over his pro-Palestine advocacy, have called on an immigration appeals court to reopen and terminate his case.

The latest legal appeal points to new evidence, some of which was documented in media reports, that Khalil’s lawyers said it “suggests that the Trump Administration secretly engineered the outcome of his immigration case to make an example of him”.

It comes just over a month after the Board of Immigration Appeals issued a final order of removal for Khalil, who was first detained by immigration enforcement agents in March 2025, one of several students targeted for their participation in pro-Palestine campus protests that swept the US the previous year.

Khalil, a US permanent resident who is married to a US citizen, has long maintained that he has been unjustly targeted for his political views.

His legal team said on Friday that “apparent procedural abnormalities” support that view.

“It’s clear that the revelations of DOJ misconduct corroborate what we have known since Mahmoud was arrested–that the administration has reverse-engineered its desired outcome by weaponising a farcical proceeding littered with abnormalities,” Johnny Sinodis, a lawyer representing Khalil, said in a statement.

The new evidence includes a report by The New York Times that found that Khalil’s case had been flagged as high priority before it had arrived at the Board of Immigration Appeals, in what his lawyers say indicated the case was being “fast-tracked”.

The report, citing case documents, also found that the court had been instructed to treat Khalil’s case as if he were still in detention custody, which typically results in an expedited processing timeline.

Khalil was released from immigration detention in June 2025 following a federal judge’s order. An appeals court later ruled the judge did not have jurisdiction over the matter. He is also appealing that decision, during which time authorities are barred from re-detaining or deporting him.

The New York Times report also found that three judges at the Board of Immigration Appeals recused themselves from the case. While the reasons for the recusals were not made public, experts familiar with the board’s procedures have said the rate of recusals was extremely rare.

The Board of Immigration Appeals is meant to be independent. Like other immigration courts, it falls under the Department of Justice in the executive branch, which critics say makes it more vulnerable to interference.

Other federal courts fall under the independence of the judicial branch.

The Trump administration has framed Khalil’s deportation as part of a crackdown on anti-Semitism. They have presented no evidence to back the claims against him, and Khalil has never been charged with a crime.

This week, The Intercept news site reported that shortly after he was detained by immigration agents, the FBI had closed an investigation into a tip that Khalil had called for “violence on behalf of Hamas”, saying it did not warrant further investigation.

In targeting Khalil, US Secretary of State Marco had invoked a rarely used provision of the Immigration and National Act that allows the deportation of individuals deemed to be a national security threat based on “past, current or expected beliefs, statements, or associations that are otherwise lawful”.

The manoeuvre raised questions over freedom of speech and whether those protections extended to permanent residents like Khalil. The government later added the claim that Khalil had intentionally failed to disclose his past work for the UN agency for Palestinian refugees (UNRWA) on his immigration application.

Administration officials have repeatedly stood by the claims and maintained that Khalil received proper due process.

In a statement on Friday, Khalil said the administration “wants to arrest, detain, and deport me to intimidate everyone speaking out for Palestine across this country, and they are willing to violate longstanding US rules and procedures to do it”.

He added, “No lies, corruption, or ideological persecution will stop me from advocating for Palestine and for everyone’s right to free speech.”
