(1) Within thirty days after a final decision by the commission in any proceeding, any party to the proceeding before the commission may apply to the district court for a writ of certiorari or review for the purpose of having the lawfulness of the final decision inquired into and determined. Such writ shall be made returnable not later than thirty days after the date of issuance and shall direct the commission to certify its record in the proceeding to said court. On the return day, the cause shall be heard by the district court unless, for a good reason shown, the same be continued. No new or additional evidence may be introduced in the district court, but the cause shall be heard on the record of the commission as certified by it. The commission and each party to the action or proceeding before the commission shall have the right to appear in the review proceedings.
(2) The findings and conclusions of the commission on disputed questions of fact shall be final and shall not be subject to review, except that, in any proceeding wherein the validity of any order or decision is challenged on the ground that it violates any right of a petitioner under the constitution of the United States or the constitution of the state of Colorado, the district court shall exercise an independent judgment on the law and the facts, and the findings or conclusions of the commission material to the determination of the said constitutional question shall not be final.
(3) Upon review, the district court shall enter judgment either affirming, setting aside, or modifying the decision of the commission. So far as necessary to the decision and where presented, the district court shall decide all relevant questions of law and interpret all relevant constitutional and statutory provisions. The review shall not extend further than to determine whether the commission has regularly pursued its authority, including a determination of whether the decision under review violates any right of the petitioner under the constitution of the United States or of the state of Colorado, and whether the decision of the commission is just and reasonable and whether its conclusions are in accordance with the evidence.
(4) The provisions of the Colorado rules of civil procedure relating to writs of certiorari or review, so far as applicable and not in conflict with the provisions of this title, shall apply to proceedings had in the district court under the provisions of this section. No court of this state, except the district court to the extent specified, shall have jurisdiction to review, reverse, correct, or annul any order or decision of the commission, or to suspend or delay the execution or operation thereof, or to enjoin, restrain, or interfere with the commission in the performance of its official duties; but an action in the nature of mandamus shall lie from the district court to the commission in all proper cases.
(5) All actions for review shall be commenced and tried in the district court in and for the county in which the petitioner resides, or if a corporation or partnership in the county in which it maintains its principal office or place of business, or in the district court of the city and county of Denver, at the option of the petitioner. Appellate review may be obtained in the supreme court concerning any final judgment of the district court on review, affirming, setting aside, or modifying any decision of the commission, in the same manner and with the same effect as appellate review of judgments of the district court in other civil actions.

40-6-116. Suspension of decision - notice - bond - accounting pending review. (1) The pendency of a writ of certiorari or review shall not of itself stay or suspend the operation of the decision of the commission; but, during the pendency of such writ, the district court, in its discretion, may stay or suspend, in whole or in part, the operation of the commission's decision.
(2) No order so staying or suspending any decision of the commission shall be made other than upon three days' notice and after hearing; and if the decision of the commission is suspended, the order suspending the same shall contain a specific finding based upon evidence submitted to the court and identified by reference thereto that great or irreparable damage would otherwise result to the petitioner and specifying the nature of the damage.
(3) In case the decision of the commission is stayed or suspended, the order of the court shall not become effective until a suspending bond has been filed with and approved by the district court, and sufficient in amount and security to ensure the prompt payment, by the party petitioning for the review, of all damages caused by the delay in the enforcement of the decision of the commission, and of all money which any person may be compelled to pay, pending the review proceedings, for transportation, transmission, product, commodity, or service in excess of the charges fixed by the decision of the commission in case said decision is sustained. The district court, in case it stays or suspends the decision of the commission in any matter affecting rates, fares, tolls, rentals, charges, or classifications, by order, shall direct the public utility affected to pay into court from time to time, there to be impounded until the final decision of the case, or into some bank or trust company under such conditions as the court may prescribe all sums of money which it may collect from any person in excess of the sum such person would have been compelled to pay if the decision of the commission had not been stayed or suspended.
(4) In case the district court stays or suspends any decision lowering any rate, fare, toll, rental, charge, or classification, the commission, upon the filing and approval of said suspending bond, shall forthwith require the public utility affected, under penalty of the immediate enforcement of the decision of the commission, pending review and notwithstanding the suspending order, to keep such accounts, verified by oath, as may, in the judgment of the commission, suffice to show the amounts being charged or received by such public utility, pending review, in excess of the charges allowed by the decision of the commission, together with the names and addresses of the persons to whom overcharges will be refundable in case the charges made by the public utility, pending review, are not sustained by the district court. The court, from time to time, may require the party petitioning for a review to give additional security on, or to increase, the suspending bond, whenever in the opinion of the court the same may be necessary to ensure the prompt payment of said damages and said overcharges.
(5) Upon the final decision by the district court, all money which the public utility may have collected, pending the appeal, in excess of those authorized by such final decision, together with interest, in case the court ordered the deposits of such moneys in a bank or trust company, shall be promptly paid to the persons entitled thereto, in such manner and through such methods of distribution as may be prescribed by the commission. If any moneys are not claimed by the persons entitled thereto within one year from the final decision of the district court, the commission shall cause notice to such persons to be given by publication once a week for two successive weeks in a newspaper of general circulation printed and published in the city and county of Denver and in such other newspapers as may be designated by the commission, said notice to state the names of persons entitled to such moneys and the amounts due each person. All moneys not claimed within ninety days after publication of such notice shall be paid by the public utility, under the direction of the commission, into the state treasury and credited to the general fund.
