The court's decision comes after officials uncovered a database error that for two decades mistakenly designated the voters as having access to the full ballot.

The Arizona Supreme Court ruled Friday that nearly 100,000 residents who may not have fulfilled the state’s proof-of-citizenship requirements can still vote in state and local races this year, quickly resolving how election officials should address a clerical glitch that had left the eligibility of those registered voters in question.

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