Colo. Rev. Stat. § 1-11-204
The supreme court of this state has original jurisdiction for the adjudication of contests concerning presidential electors and shall prescribe rules for practice and proceedings for such contests. No justice of the court who is a contestor in the election contest shall be permitted to hear and determine the matter. A contest must be filed with the supreme court no later than twenty-four days after the general election notwithstanding the fact that a recount may be ongoing. The supreme court is required to rule on a contest before the deadline to issue and submit the certificate of ascertainment pursuant to the requirements of the federal "Electoral Count Reform and Presidential Transition Improvement Act of 2022", 3 U.S.C. sec. 5. The supreme court shall prioritize election contests of presidential electors over all regular business of the court so that election results are determined as soon as practicable.
