WASHINGTON — The Supreme Court on Tuesday rebuffed the Trump administration over its plan to deploy National Guard troops in Illinois over the strenuous objections of local officials.

The court in an unsigned order turned away an emergency request made by the administration, which said the troops are needed to protect federal agents involved in immigration enforcement in the Chicago area.

In doing so, the court at least provisionally rejected the Trump administration’s view that the situation on the ground is so chaotic that it justifies invoking a federal law that allows the president to call National Guard troops into federal service in extreme situations.

Those circumstances can include when “there is a rebellion or danger of a rebellion” or “the president is unable with the regular forces to execute the laws of the United States.”

Among the issues in the case is what the term “regular forces” means, something the Supreme Court focused on in an order issued on Oct. 29 asking for additional briefing. The question is whether the law only allows for the National Guard to be called up if regular military forces are unable to restore order, or whether the phrase refers to law enforcement.
