What it's about

The Court will decide whether federal voter-registration law or a prior consent decree blocks those measures, including cancellations made within 90 days of a federal election.

The dispute tests how federal voter-registration rules and a prior consent decree (a court-approved agreement) limit state election rules.

Question presented

1. Does the National Voter Registration Act or a federal consent decree prohibit Arizona from requiring voter-registration applicants to produce "satisfactory evidence" of U.S. citizenship when registering with a state registration form? 2. Does the National Voter Registration Act prohibit Arizona from implementing a program within 90 days of a federal election to cancel the registrations of voters who are not U.S. citizens?
