Arizona v. United States

Docket No., 11-182

Argument Date: Wednesday, April 25

Questions Presented

Arizona enacted the Support Our Law Enforcement and Safe Neighborhoods Act (S.B. 1070) to address the illegal immigration crisis in the State. The four provisions of S.B. 1070 enjoined by the courts below authorize and direct state law-enforcement officers to cooperate and communicate with federal officials regarding the enforcement of federal immigration law and impose penalties under state law for non-compliance with federal immigration requirements.

The question presented is whether the federal immigration laws preclude's efforts at cooperative law enforcement and impliedly preempt these four provisions of S.B. 1070 on their face.
