The U.S. Supreme Court agrees to take up a dispute over whether Arizona can require documentary proof of U.S. citizenship from people when they register to vote. Several outlets report that the case centers on Arizona’s process for voter registration, including the use of state forms that incorporate a requirement for proof of citizenship. The question before the Court is whether Arizona’s requirement violates federal law.

The decision to hear the case is expected to come during the Court’s next term, according to the reports. The New York Times notes that the case could affect how states implement stricter voter registration rules, and frames the review in the context of broader political efforts to tighten registration requirements.

Overall, the sources describe the Court’s action as a review of the legality of Arizona’s citizenship proof requirement as applied through voter registration procedures and forms. The outcome could shape the degree to which other states may adopt or maintain similar documentation requirements.
