The former president has once again threatened to deploy the Act of Insurrection, a statute that allows the president to deploy armed forces on US soil. This step is considered a strategy to control the mobilization of the national guard as judicial bodies and executives in cities under Democratic control continue to stymie his attempts.

Is this permissible, and what are the implications? This is key information about this centuries-old law.

What is the Insurrection Act?

The statute is a US federal law that provides the president the ability to utilize the military or nationalize state guard forces domestically to suppress civil unrest.

The act is commonly known as the 1807 Insurrection Act, the year when Jefferson enacted it. Yet, the current act is a amalgamation of laws established between the late 18th and 19th centuries that define the duties of the armed forces in civilian policing.

Typically, US troops are not allowed from carrying out police functions against US citizens except in emergency situations.

The law permits troops to take part in internal policing duties such as making arrests and executing search operations, tasks they are generally otherwise prohibited from engaging in.

An authority stated that National Guard units cannot legally engage in ordinary law enforcement activities without the president first invokes the Insurrection Act, which authorizes the deployment of armed forces domestically in the case of an insurrection or rebellion.

This step heightens the possibility that military personnel could employ lethal means while filling that “protection” role. Additionally, it could be a forerunner to additional, more forceful military deployments in the future.

“There’s nothing these forces are permitted to undertake that, such as law enforcement agents opposed by these demonstrations could not do themselves,” the expert stated.

Historical Uses of the Insurrection Act

The act has been deployed on dozens of occasions. This and similar statutes were utilized during the civil rights movement in the 1960s to safeguard activists and students integrating schools. Eisenhower deployed the 101st Airborne Division to Little Rock, Arkansas to shield Black students attending the school after the state governor mobilized the National Guard to prevent their attendance.

Following that period, yet, its application has become highly infrequent, as per a study by the Congressional Research Service.

President Bush invoked the law to tackle riots in LA in the early 90s after four white police officers seen assaulting the Black motorist King were cleared, resulting in lethal violence. The state’s leader had requested military aid from the president to suppress the unrest.

Trump’s Past Actions Regarding the Insurrection Act

Donald Trump warned to use the act in June when the state’s leader sued the administration to prevent the use of military forces to accompany federal immigration enforcement in Los Angeles, calling it an “illegal deployment”.

During 2020, he requested leaders of several states to deploy their national guard troops to Washington DC to suppress demonstrations that emerged after Floyd was killed by a Minneapolis police officer. A number of the leaders complied, dispatching troops to the federal district.

At the time, the president also warned to invoke the statute for demonstrations following the killing but ultimately refrained.

While campaigning for his second term, he implied that would change. The former president told an crowd in the location in 2023 that he had been blocked from using the military to quell disturbances in locations during his initial term, and stated that if the issue came up again in his next term, “I will not hesitate.”

He has also vowed to utilize the national guard to assist in his immigration objectives.

He remarked on Monday that up to now it had not been required to use the act but that he would consider doing so.

“There exists an Act of Insurrection for a reason,” the former president stated. “In case fatalities occurred and legal obstacles arose, or governors or mayors were impeding progress, certainly, I would act.”

Why is the Insurrection Act so controversial?

There is a long historical practice of keeping the federal military out of civil matters.

The nation’s founders, following experiences with overreach by the British forces during colonial times, were concerned that giving the commander-in-chief total authority over troops would undermine civil liberties and the democratic system. According to the Constitution, governors generally have the power to ensure stability within state borders.

These principles are embodied in the Posse Comitatus Law, an 19th-century law that usually restricted the military from taking part in police duties. The law serves as a statutory exception to the Posse Comitatus Act.

Civil rights groups have long warned that the Insurrection Act gives the commander-in-chief sweeping powers to deploy troops as a internal security unit in methods the founders did not intend.

Can a court stop Trump from using the Insurrection Act?

Judges have been reluctant to question a president’s military declarations, and the appellate court noted that the commander’s action to deploy troops is entitled to a “significant judicial deference”.
