The Supreme Court agreed on June 29 to hear a challenge brought by the Republican National Committee to Arizona's requirement that voters provide documentary proof of citizenship when registering to vote [1]. The case, *RNC v. Mi Familia Vota*, tests whether that requirement conflicts with the National Voter Registration Act, the 1993 federal statute that established minimum standards for voter registration and requires states to accept a federal registration form that does not demand documentary proof of citizenship [1] [2].
The cert grant follows a Ninth Circuit ruling that found Arizona's proof-of-citizenship laws violated the NVRA [1]. The RNC petitioned the Supreme Court to reverse that decision, arguing that states retain authority to set eligibility standards, including citizenship verification requirements, for their own elections [2]. Mi Familia Vota, an Arizona-based voter registration organization, is the lead respondent defending the Ninth Circuit's judgment. The case will be argued during the 2026-27 term [1].
The central legal question is whether the NVRA preempts state laws that go beyond the federal form's requirements. A ruling for the RNC would significantly narrow the preemptive force of the NVRA, freeing states to impose documentary requirements that the federal registration process does not currently demand [1]. At least a dozen states have enacted or are advancing similar proof-of-citizenship measures, meaning the Court's decision could affect the registration eligibility of tens of millions of voters nationally [1]. The case also carries political weight: Congress has been debating the Safeguard American Voter Eligibility Act, a federal bill that would impose a national proof-of-citizenship requirement for voter registration, making the Court's interpretation of the NVRA directly relevant to the legislation's legal durability [1] [2].
Briefing schedules have not yet been publicly set. Oral argument is expected in the fall or winter of the 2026-27 term, with a decision likely by late spring 2027 [1]. Voting-rights advocates have flagged the case as one of the most consequential election-law matters the Court has agreed to hear in years, given its potential to reshape the federal-state balance in voter registration administration [1].
