González v. Arizona (2:06-cv-1268), Inter Tribal Council of Arizona v. Brewer (3:06-cv-1362), and Navajo Nation v. Brewer (3:06-cv-1575) (Roslyn O. Silver, D. Ariz.)
Four months before Arizona’s 2006 primary election, a federal complaint challenged proposition 200, a 2004 initiative that enhanced requirements for proof of citizenship for voter registration and proof of identity and residence for voting. The district court acted quickly on the plaintiffs’ motions for a temporary restraining order but denied injunctive relief. In 2012, the court of appeals determined en banc that the proof of citizenship procedure for registration is superseded by the National Voter Registration Act but the identification requirement for voting is not. The Supreme Court agreed that the required federal registration form did not permit additional evidence of citizenship.
