Challenge Procedure. If a voter is challenged, the warden shall ask the challenger to briefly set forth factual information specific and personal to the challenged voter as to the reasons that voter is not qualified to vote in the election in that precinct. If the election officer determines that the challenge is valid the warden shall administer the following oath to the challenged person:
"You do solemnly swear (or affirm) that you are the identical person whom you represent yourself to be, that you are registered in this precinct, and that you have not voted in this primary (or election)."
The warden shall require the challenged person to write his name and present residence on the outside of the ballot. (If it is an absentee ballot, the warden shall insert this information.) The warden shall add the name and address of the challenger and the stated reason for the challenge, and the voter may cast the ballot in the ballot box. No statement shall be made or information given by any person as to how the person voted. The clerk of the precinct shall record in the clerk's election record the name and residence of every person who is challenged and has voted. The election officers in charge of the voting list shall mark the letters "CV" next to the challenged voter's name on the voting list.
If the election officer determines that the challenger has not provided factual information specific and personal to that voter demonstrating that the voter is not qualified to vote at that precinct, the election officer shall reject the challenge on the grounds that the challenge was not based upon a legal cause. The election officer shall note in the clerk's election record the name of the challenged voter, the name of the challenger, the factual basis for the challenge and the reason why the challenge was rejected.
