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.

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