WASHINGTON — The American Civil Liberties Union, Democracy Forward, and the ACLU of the District of Columbia sued the Trump administration today over the president’s expected unlawful and unprecedented invocation of the Alien Enemies Act.

The Alien Enemies Act, passed in 1798, is a wartime authority providing that the president may — after a public proclamation — apprehend, restrain, and remove citizens of a foreign country that is engaged in a “declared war” or “invasion or predatory incursion” against the United States.

The lawsuit charges that President Trump intends to invoke the centuries-old wartime act unlawfully during peacetime to accelerate mass deportations, sidestepping the limits of this wartime authority and the procedures and protections in immigration law.

The Alien Enemies Act’s previous use during wartime — for example, its invocation during World War II to justify the internment of people of Japanese ancestry — has correctly drawn sustained criticism. Employing it as a way to evade domestic laws in peacetime is fundamentally wrong.

“The Trump administration’s intent to use a wartime authority for immigration enforcement is as unprecedented as it is lawless. It may be the administration's most extreme measure yet, and that is saying a lot,” said Lee Gelernt, deputy director of the ACLU’s Immigrants’ Rights Project and lead counsel.

“The United States is not at war, nor has it been invaded. The president’s anticipated invocation of wartime authority — which is not needed to conduct lawful immigration enforcement operations — is the latest step in an accelerating authoritarian playbook,” said Skye Perryman, president and CEO of Democracy Forward. “From improperly apprehending American citizens, to violating the ability of communities to peacefully worship, to now improperly trying to invoke a law that is responsible for some of our nation’s most shameful actions, this administration’s immigration agenda is as lawless as it is harmful.”

“There is no foreign military action to justify President Trump’s intended invocation of this act, making his actions not only unlawful but an outright assault on fundamental rights. This is yet another dangerous overreach by the administration, designed to support an unchecked mass deportation program, all while bypassing the necessary judicial review,” said Arthur Spitzer, senior counsel at the ACLU of the District of Columbia.
