🔥 Trending Supreme Court to Review Arizona's Proof of Citizenship Voting Law

The U.S. Supreme Court has not yet issued a final ruling on Arizona's proof of citizenship voting law. On June 29, 2026, the Supreme Court announced it would hear a case challenging two Arizona laws that require prospective voters to provide documentary proof of citizenship to register to vote ²³⁵.

Background of the Case

Arizona's law, enacted by Republicans in 2022, mandates that individuals provide proof of citizenship to register to vote, particularly for those using a state-specific registration form ¹⁵. This legislation also includes provisions for election officials to remove non-citizens from voter rolls ⁶⁸.

This is not the first time Arizona's proof of citizenship requirements have been challenged. An earlier attempt by Arizona to impose such a requirement was invalidated by a Supreme Court ruling in 2013 ¹. The current case, Republican National Committee v. Mi Familia Vota, revives this long-running dispute ⁴⁷⁸.

Key Aspects of the Dispute

The core of the legal challenge revolves around whether states can unilaterally impose proof of citizenship requirements for voter registration, especially when federal law allows individuals to register using a national form that only requires an attestation of citizenship under penalty of perjury. Opponents of the Arizona law argue that it creates an undue burden on voters and potentially disenfranchises eligible citizens, while proponents maintain it is necessary to ensure election integrity and prevent non-citizens from voting ³.

The 9th Circuit Court of Appeals had previously put the Arizona law on hold, leading to the appeal by the Republican National Committee that the Supreme Court has now agreed to hear ⁴. The Supreme Court's decision to take up this case could have significant implications for voting laws across the United States ³.
