The U.S. Supreme Court blocked National Guard deployment to Chicago in a majority opinion, supported by Justice Brett Kavanaugh.
The opinion defines 'regular forces' as active-duty military, not civilian law enforcement.
The ruling complicates U.S. President Donald Trump's plans to deploy the Guard and could push him to invoke the Insurrection Act.
Dissenting Justices Samuel Alito and Clarence Thomas warn the decision may limit future military involvement in law enforcement.

History

Historical Context

The Insurrection Act of 1807 empowers the U.S. president to deploy military forces to quell civil disorder. It has been invoked multiple times, notably by Presidents Eisenhower and Kennedy during desegregation efforts. A recent Supreme Court ruling clarifying 'regular forces' complicates potential future uses of the Act, impacting governmental responses to civil unrest, such as the protests following George Floyd's death in 2020.
