A federal appeals court ruled that President Donald Trump unlawfully invoked an 18th-century wartime law to deport Venezuelan migrants, blocking a key administration policy.
At a Glance
- A divided three-judge panel of the Fifth Circuit ruled Trump could not use the Alien Enemies Act to expedite deportations
- Judges found that alleged gang activity did not meet the statute’s “invasion” threshold
- The ruling halts deportations to El Salvador and puts the issue on course for Supreme Court review
Wartime Law Rejected
A federal appeals court has blocked President Trump’s use of the 1798 Alien Enemies Act to justify deportations of Venezuelan migrants alleged to be affiliated with the Tren de Aragua gang. In a 2–1 decision, the Fifth Circuit Court of Appeals ruled the law—which has historically only been applied during formal wartime conditions—could not be used to authorize immigration actions based on gang affiliations. The majority found that the administration failed to meet the legal threshold of an “invasion” or foreign “predatory incursion.”
The case centered on migrants detained and slated for deportation to a facility in El Salvador. The Trump administration claimed their removal was justified under the centuries-old law, citing national security concerns and criminal activity. However, the court found that these justifications did not match the historical and legal precedent set by prior uses of the Alien Enemies Act, which had only been invoked during conflicts like the War of 1812 and World War II.

Legal Arguments and Dissent
The court emphasized that the law does not grant the executive branch unilateral authority to bypass normal immigration procedures based on generalized claims of gang violence. In rejecting the administration’s interpretation, the judges underscored that no declaration of war or comparable military conflict exists between the U.S. and Venezuela. The use of the act, they said, must be connected to actual warfare, not criminal allegations.
In dissent, Judge James Ho argued the decision constrains executive power in matters of national security. He warned that denying the president authority to act against foreign nationals linked to transnational gangs could limit future responses to urgent threats. The administration had also asked the court to assess whether the seven-day notice provided to migrants was legally sufficient. That procedural question remains unresolved.
Broader Fallout
The Fifth Circuit decision represents a substantial setback for Trump’s aggressive immigration agenda. In addition to attempting to deport Venezuelans under the Alien Enemies Act, the administration has pursued policies to halt asylum claims, suspend refugee resettlement, and roll back humanitarian protections for migrants from conflict zones. By limiting the applicability of the Alien Enemies Act, the court has placed one of the administration’s most controversial enforcement strategies on unstable legal footing.
The decision clears the way for a likely Supreme Court showdown. Earlier this summer, the high court intervened with an emergency order to pause deportations, indicating a willingness to weigh in on the statute’s modern relevance. Until then, deportations under the contested program will remain suspended, affecting hundreds of migrants currently held in federal custody.
