The Supreme Court, in a surprising turn, placed a notable check on former president Donald Trump’s authority to deploy military force against American citizens, ruling against him in Trump v. Illinois. The decision, handed down Tuesday, marks a rare instance of the Court curtailing the scope of presidential power after previously upholding Trump’s broad claims of executive privilege.
The case stemmed from Trump’s deployment of approximately 300 National Guard members to Broadview, Illinois – a suburb roughly 12 miles west of Chicago – to quell protests outside an immigration detention facility. According to a federal district judge who initially heard the case, the protests were consistently small, with “the typical number of protestors [being] fewer than fifty” and never exceeding 200.
Despite the limited scale of the demonstrations, trump asserted his authority to utilize the National Guard under a federal law allowing the federal government to assume control of state-controlled Guard units in instances of “a rebellion or danger of a rebellion against the authority of the Government of the United States” or when the President deems they are “unable with the regular forces to execute the laws of the United States.”
The Court did not address Trump’s contention that the protesters constituted a “rebellion,” instead focusing on the “unable” clause. The ruling clarifies that “regular forces,” as defined by the statute, “likely refers to the regular forces of the United states military” – the Army, Navy, Air Force, and Marines. This effectively means Trump could not deploy the National Guard unless he could demonstrate an inability to enforce the law using the full resources of the U.S. military.
This aspect of the ruling has raised concerns, as it perhaps invites Trump to attempt deploying regular military forces against domestic protesters. However, the Court also indicated that even the use of the regular military is subject to limitations. The circumstances for such deployment must be “extraordinary,” as another federal law prohibits the military from “execut[ing] the laws” except in situations “expressly authorized by the Constitution or Act of Congress.” The Court noted that Trump had not invoked any such authorizing statute.
The Insurrection Act Remains a Potential Flashpoint
The illinois order is unlikely to be the final word on this issue. Justice Brett Kavanaugh, in a concurring opinion, signaled a willingness to rule against Trump on narrower grounds, suggesting the majority’s decision was a bare minimum. Kavanaugh cautioned that Trump could potentially attempt to deploy troops under the Insurrection Act, which allows the military to suppress “insurrection, domestic violence, unlawful combination, or conspiracy.”
Though, the Justice Department has historically interpreted the Insurrection Act narrowly. A 1964 memorandum from then-Deputy Attorney General Nicholas Katzenbach stipulated that the Act should only be invoked when violence is either sanctioned by state authorities or when actors have effectively seized control of an area, akin to the Ku Klux Klan’s actions in the 1870s.
Whether the five justices who sided against Trump will uphold this narrow interpretation if he attempts to invoke the Insurrection Act remains to be seen.Nevertheless, the Illinois ruling demonstrates a clear skepticism within the Court regarding a president claiming expansive authority to use the military against American citizens.
Dissenting Voices Advocate for Broader Presidential Power
The decision was not unanimous. Justice Samuel Alito, considered the Court’s most conservative voice, authored a dissenting opinion arguing that Trump should have broad authority to deploy military force. Alito asserted that Trump need only “determine that the regular forces of the United States are not sufficient” to overcome the “unable” language in the law. This view was joined only by Justice Clarence Thomas. Justice Neil Gorsuch also dissented, but primarily on procedural grounds.
The bottom line is that, for the present, a slim majority of the Supreme court has affirmed that Trump does not possess unlimited power to utilize military force against U.S. citizens on domestic soil. This ruling represents a crucial, if tentative, safeguard against the potential for presidential overreach in the realm of domestic law enforcement.
