C.R.S. § 1-9-208: Challenges of provisional ballots.

The ballot of any provisional voter may be challenged using a challenge form signed by the challenger under penalty of perjury setting forth the name of the person challenged and the basis for the challenge. Challenged provisional ballots, except those rejected for submission of multiple ballots, must be counted if the other requirements for counting provisional ballots are satisfied. The election judges shall deliver all challenges, together with the affidavits of the persons challenged, to the county clerk and recorder or the designated election official.
