President Donald Trump’s invocation of the Alien Enemies Act has faced intense preliminary litigation in courts around the country, leading to rulings such as the Supreme Court’s insistence that people potentially subject to the act must receive due process. But a new and significant ruling from a Trump-appointed judge Thursday gets to the heart of the matter, deeming the president’s invocation itself “unlawful.”
The 1798 act was previously used only during declared wars. The text of the act says it’s for “[w]henever there is a declared war between the United States and any foreign nation or government, or any invasion or predatory incursion is perpetrated, attempted or threatened against the territory of the United States by any foreign nation or government.”
Trump’s March proclamation targeted the Venezuelan gang Tren de Aragua. In an attempt to tie the gang officially to another country under the act, the proclamation said that Venezuelan authorities had ceded such control to criminal organizations like TdA that it had created “a hybrid criminal state that is perpetrating an invasion of and predatory incursion into the United States.”
But U.S. District Judge Fernando Rodriguez Jr. said that Trump’s invocation “exceeds the scope of the statute and, as a result, is unlawful.” The judge said the administration therefore can’t use the act to detain Venezuelans, transfer them within the U.S. or remove them from the country. The ruling applies to a class of plaintiffs in the Southern District of Texas.
The Trump appointee reviewed the historical record from the time of the act’s passage and found that the terms “invasion” or “predatory incursion” are meant to refer to “an organized, armed force entering the United States to engage in conduct destructive of property and human life in a specific geographical area.” Applying that background to Trump’s proclamation, the judge said TdA’s activities as described in the proclamation don’t qualify under the act.
