The Arizona Supreme Court unanimously ruled Friday that nearly 98,000 people whose citizenship documents hadn’t been confirmed can vote in state and local races, a significant decision that could influence ballot measures and tight legislative races.

The Arizona Supreme Court decided on Friday to allow nearly 100,000 people who registered to vote over the last 20 years to keep the right to vote a full ballot after a lawsuit stemming from a glitch raised concerns.

Nearly 100,000 voters will receive regular ballots this fall even though there is no record that they submitted citizenship documentation, as is required to vote in state and local elections.
