Arizona v. Inter Tribal Council of Arizona, Inc. http://www.supremecourt.gov/opinions/12pdf/12-71_7l48.pdf Justice Scalia, writing for himself, Roberts, Ginsburg, Breyer, Sotomayor and Kagan with Kennedy joining in part and concurring in the judgment. Thomas and Alito dissenting. Held that the portion of Arizona law requiring Arizona officials to reject any application for voter registration, including the "federal form" application, which is not accompanied by satisfactory documentary evidence of citizenship is preempted by the National Voter Registration Act of 1993 (the NVRA) which requires states to accept and use the uniform "federal form" for registering voters for federal elections. As a note, the federal form requires the applicant to certify under penalty of perjury that they are a United States citizen, but the Arizona law called for elections officials to reject certified federal forms unless they were also accompanied by documentary evidence of citizenship. The Supreme Court held that this requirement unlawfully conflicted with the NVRA and struck it down.
