Which case involved the tension between state immigration enforcement and federal authority?

• A. Arizona v. United States
• B. Chae Chan Ping
• C. Arizona v. Hicks
• D. United States v. Nixon

Answer: (A)

Immigration policy and enforcement is a flashpoint for the balance of power between states and the federal government. Arizona v. United States centers on a state trying to enforce immigration laws through its own measures, raising the question of whether state-level enforcement can operate without clashing with federal authority. The Supreme Court’s decision underscored that immigration is largely a federal matter and that state actions can be preempted or limited when they intrude on federal control, illustrating the tension between state efforts and federal supremacy in immigration enforcement. The other cases involve different legal issues—Chae Chan Ping deals with federal authority over immigration in general, United States v. Nixon concerns executive privilege, and Arizona v. Hicks concerns Fourth Amendment rights—so they don’t address the same state-versus-federal clash over immigration as clearly.
