The American Civil Liberties Union (ACLU), Democracy Forward, and the ACLU of the District of Columbia sued the Trump administration over President Trump’s “unlawful and unprecedented invocation” of the Alien Enemies Act of 1798 (AEA), a wartime authority, to round up and deport Venezuelans from the United States without due process that it asserted were gang members. The complaint notes that:
[T]he AEA has only ever been a power invoked in time of war, and plainly only applies to warlike actions: it cannot be used here against nationals of a country—Venezuela—with whom the United States is not at war, which is not invading the United States, and which has not launched a predatory incursion into the United States. The government’s Proclamation would allow agents to immediately put noncitizens on planes without any review of any aspect of the determination that they are Alien Enemies. Upon information and belief, the government has transferred Venezuelans who are in ongoing immigration proceedings in other states, bringing them to Texas to prepare to summarily remove them and to do so before any judicial review—including by [the U.S. District Court for the District of Columbia]. For that reason, Plaintiffs-Petitioners and the putative class that they represent seek this Court’s intervention to temporarily restrain these summary removals, and to determine that this use of the AEA is unlawful and must be stopped.
The ACLU noted that on March 15, 2025, a federal judge “broadened the scope of a temporary restraining order (TRO) blocking the Trump administration from removing immigrants from the United States using the Alien Enemies Act. The ruling extended the order to everyone in danger of removal under the act and granted class certification.” The March 15 decision said the President’s “attempt to summarily remove Venezuelan noncitizens exceeds the wartime authority that Congress delegated in the AEA, violates the process and protections that Congress has prescribed elsewhere in the country’s immigration laws for the removal of noncitizens, and violates due process.”
On March 15, apparently while the judge was holding a hearing on the ACLU case, several planes took off with hundreds of Venezuelans to be detained in a maximum-security prison in El Salvador. Many details were unclear, but Reuters published a timeline. The names of the Venezuelans on board were not released by the U.S. government, but CBS News reported names it said were on an internal government list it obtained of 238 Venezuelans taken to El Salvador. After the hearing on March 15, the judge ordered that “any plane containing these folks—because it’s going to take off or it’s in the air—needs to be returned to the United States.” Instead the planes landed in El Salvador and the Venezuelans were taken to prison.
