Colorado Revised Statutes Title 30. Government County § 30-10-605. When sheriff a party or disqualified

(1) Every coroner shall serve and execute process of every kind and perform all other duties of the sheriff when the sheriff is a party to the case, or where affidavit is made and filed as provided in this section, and in all such cases he shall exercise the powers and proceed in the same manner as prescribed for the sheriff in the performance of similar duties.

(2) Whenever any party, his agent, or attorney makes and files with the clerk of the proper court an affidavit stating that he believes that the sheriff of such county by reason of either partiality, prejudice, consanguinity, or interest, will not faithfully perform his duties in any suit commenced or about to be commenced in such court, the clerk shall direct the original process in such suit to the coroner, who shall execute the process in like manner as the sheriff might or should have done.
