Colo. Rev. Stat. § 24-50-125.3
An applicant or employee who alleges discriminatory or unfair employment practices, as defined in part 4 of article 34 of this title, in the state personnel system may appeal within ten days of the alleged practice by filing a complaint in writing with the board or the Colorado civil rights division in the department of regulatory agencies, which shall investigate such complaint on behalf of the board pursuant to the procedures and time limits set forth in section 24-34-306. In an appeal involving the civil rights division, the state personnel board shall contract with a third party to investigate the complaint. If, after said civil rights division or third party has found no probable cause or has attempted after a finding of probable cause to resolve the complaint by conference, conciliation, and persuasion, the applicant or employee remains dissatisfied, such person shall have ten days from the date he is notified of the civil rights division's or third party's action in which to appeal to the board. The board may set the complaint for hearing or adopt the findings of the civil rights division or third party as its own. If the complaint is set for hearing, it shall be subject to the same time limits as other appeals heard by the board. If the board adopts a no probable cause finding as its own, such action shall not operate to deny an employee a hearing to which he is otherwise entitled by law or rule.
