On March 15, 2025, the Trump administration invoked the Alien Enemies Act of 1798, a wartime statute rarely used in U.S. history, as part of its campaign against alleged members of Tren de Aragua. The proclamation argued that the gang's activity constituted an \"invasion\" or \"predatory incursion\" within the meaning of the statute.
\nThe administration used that theory to argue it could remove Venezuelan nationals with sharply reduced process. Critics said the policy relied on sweeping accusations of gang affiliation and did not provide individualized hearings before some removals were attempted.
\nRather than returning all deportees to Venezuela, the administration also coordinated transfers to El Salvador under an agreement with President Nayib Bukele's government. Public reporting said some deportees were sent to CECOT, where they were held in a prison system criticized by rights groups for extreme conditions and limited process.
\nThat made the policy unusual even by immigration-law standards: the United States was not just removing people from the country, but in some cases transferring them into a third country's detention system.
\nFederal courts quickly intervened. Some judges issued emergency orders blocking removals or requiring notice and a chance to challenge the government's legal theory before deportation. Other opinions later questioned whether the proclamation described the kind of \"invasion\" that Congress had in mind when it enacted the statute.
\nThe litigation turned on both process and substance: whether the Act can be used outside a conventional wartime setting, and whether the government may rely on it without individualized hearings when the consequence is immediate removal to another country or prison system.
\nJudge James Boasberg issued a temporary restraining order on March 15, 2025, blocking deportation flights under the Act. Hours later, the administration flew deportees to El Salvador despite the order. In an April 16 ruling spanning 46 pages, Boasberg found \"probable cause\" to hold the government in criminal contempt, writing that the evidence was \"sufficient for the court to conclude that probable cause exists to find the government in criminal contempt.\" He described the administration's use of the Act as having \"frightening\" implications.
\nAn appeals court later reversed the contempt finding in August 2025, in a 2-1 decision with both judges in the majority being Trump appointees.
\nTrump called for Boasberg's impeachment on Truth Social, labeling him a \"Radical Left Lunatic.\" Chief Justice John Roberts issued a rare public rebuke, stating: \"For more than two centuries, it has been established that impeachment is not an appropriate response to disagreement concerning a judicial decision.\"
\nOn September 3, 2025, the Fifth Circuit Court of Appeals delivered a decisive blow to the administration's legal theory. In a 2-1 ruling, the court blocked the use of the Alien Enemies Act for immigration removals. Judge Leslie Southwick, writing for the majority, rejected the argument that the Venezuelan gang Tren de Aragua constituted an \"invasion\" under the statute, concluding: \"We conclude that the findings do not support that an invasion or a predatory incursion has occurred.\"
\nThe ruling was significant because the Fifth Circuit -- covering Texas, Louisiana, and Mississippi -- is widely regarded as one of the most conservative appellate courts in the country. That even this court rejected the administration's legal theory underscored how far the invocation of a wartime statute for immigration enforcement departed from established law.
\nThe Act had previously been used only during declared wars: the War of 1812, World War I, and World War II. Its use to justify peacetime immigration deportations was unprecedented.
\nThis publication assigns a critical label because the reported conduct raises several unusually serious issues at once:
\nThe historical analogy matters as well: the Alien Enemies Act was previously used during formal wars, including the period that produced Japanese internment. That history does not itself decide the legality of the 2025 proclamation, but it explains why the policy drew immediate scrutiny from civil-liberties advocates, courts, and scholars.
