Colorado Revised Statutes Title 13. Courts and Court Procedure § 13-16-113. Costs upon dismissal or summary judgment

(1) In all cases where any action is dismissed for irregularity, or is nonprossed or nonsuited by reason that the plaintiff neglects to prosecute the same, the defendant shall have judgment for his costs.

(2) In all actions brought as a result of a death or an injury to person or property occasioned by the tort of any other person, where any such action is dismissed prior to trial under rule 12(b) of the Colorado rules of civil procedure, the defendant shall have judgment for his costs. This subsection (2) shall not apply if a motion under rule 12(b)(5) of the Colorado rules of civil procedure is treated as a motion for summary judgment and disposed of as provided in rule 56 of the Colorado rules of civil procedure.
