In Arizona v. United States (2012), the U.S. Supreme Court struck down the provisions of a state law making illegal entry into the country a state offense, banning undocumented immigrants from working in the state, and allowing warrantless arrests of those suspected of deportable offenses. Noting that the U.S. Constitution grants authority over immigration solely to the federal government, the Court held that these provisions were preempted by federal law. However, the Court refused to strike down the most controversial provision of the bill, which required police to verify immigration status if they had reasonable suspicion that someone is an illegal immigrant. The Court remanded this issue to the federal district court for a hearing on the constitutionality of the measure. The Court thus postponed to a later day a decision on the most controversial element of the Arizona law.
