The Supreme Court has refused to allow Florida to enforce a state law making it a crime for undocumented immigrants to enter or remain in Florida. Wednesday’s brief, unsigned order leaves in place a U.S. district judge’s ruling blocking Florida from allowing local police officers to arrest people based on their immigration status. The American Civil Liberties Union welcomed the Supreme Court’s order, writing, “This ruling affirms what the Constitution demands — that immigration enforcement is a federal matter and that no one should be stripped of their liberty without due process.”
