C.R.S. § 1-4-911

The party filing a protest has the burden of sustaining the protest by a preponderance of the evidence. The decision upon matters of substance is open to review, if prompt application is made, as provided in section 1-1-113 . The remedy in all cases shall be summary, and the decision of any court having jurisdiction shall be final and not subject to review by any other court; except that the supreme court, in the exercise of its discretion, may review any judicial proceeding in a summary way.
