Colorado Revised Statutes Title 1. Elections § 1-13.5-609. Counting paper ballots

(1) As soon as the polls at any election are finally closed, the election judges shall immediately open the ballot box and proceed to count the votes cast, and, before the election judges adjourn, the counting thereof shall continue until finished. The election judges shall first count the number of ballots in the box. If the ballots are found to exceed the number of names entered on the pollbook, the election judges shall then examine the official endorsements upon the ballots, and if, in the unanimous opinion of the judges, any of the ballots in excess of the number on the pollbook do not bear the proper official endorsement, they shall be put into a separate pile, and a separate record and return of the votes in such ballots shall be made under the heading “excess ballots”. When the ballots and the pollbook agree, the election judges shall proceed to count the votes. Each ballot shall be read and counted separately, and every name separately marked as voted for on such ballot where there is no conflict to obscure the intention of the voter, and shall be read and marked upon the tally sheets before proceeding to any other ballot. Each ballot, excepting excess ballots, shall be read and counted and placed upon the tally sheets in like manner.

(2) When all the votes have been read and counted, the ballots, together with one of the tally lists, shall be placed in a box or appropriate container, and the opening shall be carefully sealed, and each of the election judges shall place his or her initials on said seal. The sealed box shall be delivered to the designated election official pursuant to section 1-13.5-614.

(3) All persons, except election judges and watchers, are excluded from the place where the counting is being carried on until the count has been completed.
