The United States Supreme Court is set to hear oral arguments this week in the case Arizona v. United States. At issue is Arizona’s anti-immigration law, known as S. B. 1070, which requires police officers to ascertain the legal status of those they suspect of being in the U.S. illegally.
There are a variety of legal reasons why the Court can and should strike down the law. For obvious reasons, immigration policy is a federal, not a state, issue. If Arizona can find legal justification for police action that effectively creates a second juridical border, what is to keep California from pulling down the barriers that exist along its border with Mexico? Federal immigration law is enough of a mess without further complicating the issue by permitting all fifty states to enact their own separate provisions.
