Appeals court rules key Alien Enemies Act lawsuit moot

Federal Judges Decline to Rule on Alien Enemies Act After Deportations Complete

Provpnadvice.com – A federal appeals court has sidestepped a critical legal question regarding President Trump’s use of the Alien Enemies Act for rapid deportations, declaring the case moot after the plaintiffs were removed from the country. The U.S. Court of Appeals for the 5th Circuit issued its decision on Thursday, finding that the challenge no longer had practical significance since the three men who filed the lawsuit had already been deported.

The legal battle had previously traveled to the Supreme Court before returning to the 5th Circuit. The high court had intervened in the middle of the night to block a deportation flight, ruling that the migrants were entitled to at least some form of due process. The justices then sent the case back to the 5th Circuit to address broader questions about whether the president had exceeded his constitutional authority when applying the 1798-era law.

Why the Case Became Moot

The 5th Circuit judges noted a crucial detail that changed the case’s trajectory. While the three named petitioners were still in the United States when the Supreme Court remanded the matter, they were eventually deported under the Immigration and Nationality Act rather than the Alien Enemies Act. The court described this alternative legal basis as “unobjectionable.”

“The Supreme Court remanded this case to us when the three named petitioners were still in the country. But we have since learned that the government has removed them. Given this change, we conclude that the appeal is moot,” the judges wrote in their decision.

By ruling the case moot, the 5th Circuit avoided making a definitive determination on the scope of presidential power under the Alien Enemies Act. This legal doctrine permits the summary deportation of migrants during what the government characterizes as an “invasion” or “predatory incursion” by a foreign nation. The statute has been invoked historically during the War of 1812, World War I, and World War II, with its most famous application being the Japanese internment during the Second World War.

Trump’s Controversial Application of the Law

In what many legal experts called an unprecedented move, President Trump determined that members of the Venezuelan Tren de Aragua gang could be classified as a foreign enemy under the centuries-old statute. This designation allowed the administration to bypass normal immigration procedures and deport individuals more rapidly.

Multiple District Court judges subsequently ruled that Trump’s application of the law was unlawful, finding that the gang did not constitute a genuine military threat to the United States. The lawsuit at the center of this latest ruling concerned a deportation wave originally scheduled for April 2025, occurring just weeks after Trump first invoked the 1798 legislation.

The American Civil Liberties Union rushed to court on behalf of the men set to be deported, prompting the Supreme Court’s midnight intervention. The ACLU viewed Thursday’s ruling as a victory, noting that the Supreme Court’s injunction preventing the use of the Alien Enemies Act remains active.

“The Supreme Court’s injunction barring use of the Alien Enemies Act remains in place, which is essential because there are still people at risk of being wrongly removed under the act without due process. The Fifth Circuit decision also doesn’t change the fact that courts have overwhelmingly held that the use of this wartime authority during peacetime is unlawful,” said ACLU attorney Lee Gelernt, who argued the case.

Split Decision Among Judges

While the majority of the 5th Circuit judges declared the case moot, two Trump-appointed judges—Andrew Oldham and James Ho—used the opportunity to rule on the merits. They concluded that the president’s use of the Alien Enemies Act was lawful.

“And that’s what the Government is asking us to do here—terminate the litigation now, by ruling on the merits as a matter of law,” Judge Ho stated.

This represents a shift from the fall ruling by a 5th Circuit panel, which had found the president’s invocation of the AEA unlawful. Thursday’s decision came from the full bench of 5th Circuit judges rather than a smaller panel.

Human Rights Concerns in El Salvador

Although the plaintiffs in this particular case were not deported under the Alien Enemies Act, the broader deportation effort had significant consequences. In the hours following Trump’s March order, more than 100 Venezuelan men were sent to CECOT, a notorious megaprison in El Salvador known by its Spanish acronym.

These men spent months imprisoned in the facility while their attorneys challenged their removal from the United States. They were eventually released from CECOT and returned to Venezuela after a negotiated prisoner swap took place.

Human Rights Watch published a detailed report documenting the conditions these deportees faced. The organization found that “detainees were subjected to constant beatings and other forms of ill-treatment, including some cases of sexual violence. Many of these abuses constitute torture under international human rights law.”

The mootness ruling leaves several questions unresolved. Legal scholars note that the case could potentially be revisited if similar deportations occur under the Alien Enemies Act in the future. The decision also highlights the complex interplay between executive power, judicial review, and immigration enforcement in the current political landscape.

For now, the Supreme Court’s temporary injunction continues to limit the administration’s ability to use the wartime statute for peacetime deportations. The ACLU’s position remains that courts have consistently found such applications unlawful, and the current ruling does not alter that precedent. The case demonstrates how procedural developments—such as the deportation of plaintiffs under different legal authority—can resolve complex constitutional questions without requiring definitive judicial answers.
