Arizona v. United States

Arizona v. United States, 567 U.S. 387 (2012), a 5-3 U.S. Supreme Court invalidated two provisions of Arizona law concerning immigration, while upholding another.

Justice Anthony Kennedy wrote for the Court:

“

Immigration policy shapes the destiny of the Nation. On May 24, 2012, at one of this Nation's most distinguished museums of history, a dozen immigrants stood before the tattered flag that inspired Francis Scott Key to write the National Anthem. There they took the oath to become American citizens. The Smithsonian, News Release, Smithsonian Citizenship Ceremony Welcomes a Dozen New Americans (May 24, 2012), online at http://newsdesk.si.edu/releases. These naturalization ceremonies bring together men and women of different origins who now share a common destiny. They swear a common oath to renounce fidelity to foreign princes, to defend the Constitution, and to bear arms on behalf of the country when required by law. 8 CFR § 337.1(a). The history of the United States is in part made of the stories, talents, and lasting contributions of those who crossed oceans and deserts to come here. The National Government has significant power to regulate immigration. With power comes responsibility, and the sound exercise of national power over immigration depends on the Nation's meeting its responsibility to base its laws on a political will informed by searching, thoughtful, rational civic discourse. Arizona may have understandable frustrations with the problems caused by illegal immigration while that process continues, but the State may not pursue policies that undermine federal law. * * * The United States has established that §§ 3, 5(C), and 6 of S. B. 1070 are pre-empted. It was improper, however, to enjoin § 2(B) before the state courts had an opportunity to construe it and without some showing that enforcement of the provision in fact conflicts with federal immigration law and its objectives. The judgment of the Court of Appeals for the Ninth Circuit is affirmed in part and reversed in part. The case is remanded for further proceedings consistent with this opinion.
