The law signed by Gov. Ron DeSantis makes it a state crime to enter Florida after coming into the United States illegally and to re-enter the state following deportation.

The law, enacted this year, made it a crime for unauthorized migrants to enter the state. Challengers say immigration is a federal matter.

Florida's Attorney General James Uthmeier, a Republican, and other state officials filed the emergency request on June 17 asking the Supreme Court to halt the judge's order. Williams found that the Florida law was likely unconstitutional for encroaching on the federal government's exclusive authority over U.S. immigration policy.
