The case is about Arizona law on the handling of overvotes (marking more than one candidate on a ballot), which was a concern because a Recorder in a county included incorrect and unlawful instructions on how to handling overvotes on a ballot. They instructed voters to mark out a mistakenly marked candidate rather than requesting a new ballot, and the Arizona Supreme Court here ruled that it was unlawful to include the instruction in Tuesday’s election, and those overvote ballots are not to be counted.

The quote highlighted in this post is referencing that elected official’s decision to include those unlawful instructions on an official ballot.
