Supreme Court blocks Trump National Guard deployment, citing limits on presidential power and federal law
The US Supreme Court on Tuesday handed President Donald Trump a major loss for rejecting the administration’s request to strike down a temporary restraining order that barred him from deploying the National Guard in Chicago.
In a 6-3 ruling that featured dissents from Justices Neil Gorsuch, Samuel Alito, and Clarence Thomas, the Supreme Court determined that the Trump administration had not met statutory requirements needed to justify deploying the National Guard in a state over the objections of its own government.
The court noted that the administration justified its Illinois deployment—pursued alongside a federal crackdown on undocumented immigrants in and around the state’s largest city—by pointing to a law stating that the president may federalize the National Guard in the event that he is “unable with the regular forces to execute the laws of the United States.”
However, the court found that the “regular forces” referenced in the statute refers to the US military, not civilian law enforcement officials. This is relevant because the president faces significant restrictions on his ability to deploy the military domestically under the Posse Comitatus Act.
“Because the statute requires an assessment of the military’s ability to execute the laws, it likely applies only where the military could legally execute the laws,” the justices wrote. “Such circumstances are exceptional: Under the Posse Comitatus Act, the military is prohibited from ‘execut[ing] the laws’ ‘except in cases and under circumstances expressly authorized by the Constitution or act of Congress.’”
The justices further said that the Trump administration so far “has failed to identify a source of authority that would allow the military to execute the laws in Illinois” and has not invoked any statute that would provide an exception to the Posse Comitatus Act.
In conclusion, the court wrote that the federal government “has not carried its burden to show” that the law “permits the president to federalize the guard in the exercise of inherent authority to protect federal personnel and property in Illinois.”
Illinois Attorney General Kwame Raoul, who had sued the Trump administration over the implementation, cheered the ruling and said that “the extremely limited circumstances under which the federal government can call up the militia over a state’s objection does not exist in Illinois.”
Raoul added that he was “pleased that the streets of Illinois will remain free of armed National Guard members as our litigation continues in the courts.”
Glenn Kirschner, a former federal prosecutor, celebrated the Supreme Court’s ruling as a victory for the rule of law.
“Trump is losing his grip on the dictatorial power he so covets,” Kirschner commented on X.
