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 in question the eligibility of those registered voters in the critical battleground state.

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.
