The Supreme Court will review Arizona laws that require documentary proof of citizenship for state and local registration and authorize near‑election purges of voter rolls.Lower federal courts have blocked the proof‑of‑citizenship provisions and the purge procedures, finding they conflict with a federal law that prescribes a uniform registration form and a sworn attestation of citizenship.The Biden administration and voting rights groups sued to block the 2022 measures, while the Trump administration and Arizona Republicans have appealed to restore full enforcement.The court previously allowed limited emergency enforcement for state races but barred use of proof requirements to determine mail or federal ballot eligibility, and its ruling will shape how states balance fraud prevention and access to the ballot.
