Officials recently discovered that some people with driver’s licenses issued before 1996 might not have proof of citizenship on file, a state requirement since 2004.

The Republican-leaning 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, saying the voters were not at fault for a database error that for two decades mistakenly designated them as having access to the full ballot.

The decision temporarily resolves a quandary that could have disenfranchised the group and swayed down-ballot races across the state.
