Colorado Revised Statutes Title 1. Elections § 1-13.5-1303. Corrections

If, upon proceeding to canvass the votes, it clearly appears to the canvass board that in any statement produced to them certain matters are omitted that should have been inserted or that any mistakes which are merely clerical exist, the canvass board shall send the statement to the election judges from whom they were received to have the mistakes corrected. The election judges, when so demanded, shall make such corrections as the facts of the case require, but shall not change or alter any decision made before by them. The canvass board may adjourn from day to day for the purpose of obtaining and receiving the statement.
