C.R.S. § 1-13.5-511

(1) No later than sixty days before any election, the designated election official of each local government that intends to conduct an election shall certify the order of the ballot and ballot content. The order of the ballot and ballot content must include the name and office of each candidate for whom a petition or self-nomination form or letter has been filed with the designated election official and any ballot issues or ballot questions to be submitted to the eligible electors. (2) After a designated election official has certified the order of the ballot and ballot content in accordance with subsection (1) of this section, the designated election official may recertify the ballot if: (a) A candidate withdraws from a race, and the withdrawal would not change the order that the candidate names appear on the ballot as previously determined by the lot drawing; or (b) There are technical revisions to a ballot issue or ballot question prior to the ballots being printed.
