On April 9, the Wisconsin Supreme Court issued an opinion in State ex rel Zignego v Wisconsin Elections Commission, 2021 WI 32. It agrees with the State Court of Appeals, concerning a purge of the voter rolls. The decision is 5-2. The State Court of Appeals said the State Elections Commission is not obliged to carry out a purge. The specific issue is whether municipal election officials are in charge of the purge, or whether the state Commission is in charge. The Appeals Court, and the Supreme Court majority, agree local officials are in charge of purging. Voter lists are purged when there is information that a voter has moved and has not re-registered at the new address.
