Court says almost everything in that field is preempted by the national government where states cannot act without the authority of the national government. The only law arizona can do was that they can ask the federal government if an undocumented person they were holding in jail for a crime was wanted. It was okay for them to speak to a state officer. States may be precluded from legislation if congress has determined government must be exclusive. State law cannot conflict with federal law.
