Supreme Court Agrees to Hear Arizona Proof of Citizenship Voter Registration Case
In a move carrying major national implications for the 2028 presidential cycle and the ongoing battle over state-level voting rules, the U.S. Supreme Court agreed on June 29, 2026, to hear Republican National Committee v. Mi Familia Vota.
The high court accepted the RNC's appeal to review a 9th Circuit ruling that invalidated parts of Arizona's 2022 voting laws. The case will decide two critical issues: whether Arizona can require documentary proof of citizenship (such as a birth certificate or passport) for individuals registering to vote1, and whether the state can systematically purge voter rolls within 90 days of an election. The latter provision has been heavily contested by voting rights groups who argue it directly violates the National Voter Registration Act's (NVRA) "quiet period" protections designed to prevent eleventh-hour voter disenfranchisement.
Arguments are scheduled for the Supreme Court's upcoming term beginning in October 2026, setting the stage for a landmark ruling on the extent of state authority to add registration hurdles beyond the federal attestation standard.

"The high court accepted an appeal from the Republican National Committee to review a lower court decision that found provisions of the state’s 2022 voting law, which would require people to show proof of citizenship to register to vote, violated the federal National Voter Registration Act of 1993." — POLITICO
