A federal appeals panel has reversed a lower court decision that released activist Mahmoud Khalil from immigration jail. The 3rd U.S. Circuit Court of Appeals ruled that the lower court lacked jurisdiction to hear the case. This decision moves the government closer to detaining and deporting Khalil, who was a leader in pro-Palestinian protests at Columbia University. The case now returns to the immigration court system for further review. Khalil’s legal team plans to continue their appeals as the government seeks to enforce federal immigration laws.
A federal appeals panel in Philadelphia has reversed a lower court decision that allowed Mahmoud Khalil to leave an immigration jail. This ruling brings the federal government one step closer to detaining and deporting the activist. The decision came from a three-judge panel of the 3rd U.S. Circuit Court of Appeals. This panel instructed a lower court to dismiss a legal filing that had secured the release of the former Columbia University graduate student. The court case involves the proper way to handle immigration challenges under federal law.
The official rationale for this decision is based on which court has the power to hear the case. The panel ruled that the federal district court in New Jersey did not have jurisdiction over the matter. According to the ruling, federal immigration laws require deportation challenges to be made by filing a petition for review with a federal appeals court. The judges stated that the law does not allow these challenges to happen in a lower-level district court. This legal structure is designed to ensure that people get exactly one chance to argue their case in the correct venue.
The panel decided the case with a 2-1 vote. In their written opinion, the judges explained that the current legal scheme ensures that petitioners get just one bite at the apple. They noted that this means some people will have to wait to seek relief for government conduct that they claim is unlawful. The law specifically bars Khalil from using a habeas petition to attack his detention and removal. This ruling is a significant development for the current administration and its efforts to deport noncitizens who participate in certain protests.
Mahmoud Khalil is a 30-year-old Palestinian activist who was a leader in the pro-Palestinian movement at Columbia University. He was arrested at his apartment on March 8, 2025. After his arrest, he spent three months in an immigration jail located in Louisiana. During that time, he missed the birth of his first son. Federal officials have made several claims against him. They have accused him of leading activities that are aligned with Hamas. However, the government has not presented evidence to support this claim and has not accused him of any criminal conduct.
The government justified the initial arrest using a statute that is not used very often. This law allows for the expulsion of noncitizens if their beliefs are seen as a threat to the foreign policy interests of the United States. In June, a federal judge in New Jersey had ruled that this justification would likely be found unconstitutional. That judge ordered Khalil to be released from jail. The administration of President Donald Trump then appealed that ruling. They argued that the decision about deportation should be made by an immigration judge instead of a federal court.
Government officials have also raised concerns about Khalil’s green card application. They accused him of failing to disclose certain information when he applied. Khalil has stated that these allegations are baseless and ridiculous. He believes his arrest and detention are a direct result of his free speech and his advocacy for a free Palestine. He has framed the legal actions against him as a consequence of his political activities. His legal team has not yet returned messages seeking comment on the latest court decision.
The practical policy impact of this ruling involves specific legal forms and timelines for noncitizens facing deportation. Instead of filing a habeas petition in a district court, the law requires a petition for review of a final order of removal with a federal appeals court. This means that individuals like Khalil must wait for the immigration court system to finish its work before they can ask a higher court to step in. The ruling enforces the rule that immigration challenges must follow a specific path through the court system. There are no details in the report about specific fees or new paperwork costs for this process.
This legal battle is not over yet. An appeals board in the immigration court system is currently looking at a previous order from an immigration judge. That judge previously found that Khalil could be deported. The judge suggested that Khalil could be sent to Algeria or Syria. Khalil has citizenship in Algeria through a distant relative, but he was born in a refugee camp in Syria. His lawyers have argued that he would face mortal danger if he were forced to go to either country.
The case will now return to the lower court to be dismissed as the appeals panel instructed. Khalil’s attorneys have stated that they plan to exhaust all of their appeal options. The immigration court system will continue to weigh the previous deportation order. Federal oversight of the case will continue as the government moves forward with its efforts to enforce immigration statutes.
