U.S. Sup. Ct.

The National Voter Registration Act of 1993 (NVRA) requires States to “accept and use” a uniform federal form to register voters for federal elections. 42 U. S. C. §1973gg–4(a)(1). That “Federal Form,” developed by the federal Election Assistance Commission (EAC), requires only that an applicant aver, under penalty of perjury, that he is a citizen. Arizona law, however, requires voter-registration officials to “reject” any application for registration, including a Federal Form, that is not accompanied by documentary evidence of citizenship. Respondents, a group of individual Arizona residents and a group of nonprofit organizations, sought to enjoin that Arizona law. Ultimately, the District Court granted Arizona summary judgment on respondents’ claim that the NVRA pre-empts Arizona’s requirement. The Ninth Circuit affirmed in part but reversed as relevant here, holding that the state law’s documentary-proof-of-citizenship requirement is pre-empted by the NVRA.
