Now, let’s practice another provisional situation!
Bob Voter comes in the afternoon, but is marked as having already voted. He mentions that his son (Bob Voter, Jr.) lives with him and voted earlier that day around 10:30 AM.
As we discussed in the Non-Routine section, this is most likely due to an officer checking in the wrong voter. Because you cannot edit the previous check-in, you must offer the voter in front of you a provisional ballot. The Electoral Board will then review the situation and determine if his ballot should be counted.
