Section 220 ILCS 5/10-204(a) The pendency of an appeal shall not of itself stay or suspend the operation of the rule, regulation, order or decision of the Commission, but during the pendency of the appeal the reviewing court may in its discretion stay or suspend, in whole or in part, the operation of the Commission's rule, regulation, order or decision. Any stocks or stock certificates, bonds, notes, or other evidence of indebtedness issued pursuant to and in accordance with an order of the Commission shall be valid and binding in accordance with their terms notwithstanding such order of the Commission is later vacated, modified, or otherwise held to be wholly or partly invalid unless operation of such order of the Commission has been stayed or suspended by the reviewing court prior to such issuance.(b) No order so staying or suspending a rule, regulation, order or decision of the Commission shall be made by the court otherwise than upon 3 days' notice to the Commission and after a hearing, and if the rule, regulation, order or 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.(c) In case the rule, regulation, order or decision of the Commission is stayed or suspended, the order of the court shall not become effective until a suspending bond shall first have been executed and filed with, and approved by the Commission (or approved, on review, by the court) payable to the people of the State of Illinois, and sufficient in amount and security to insure the prompt payment, by the party petitioning for the review, of all damages caused by the delay in the enforcement of the rule, regulation, order or decision of the Commission, and of all moneys which any person or corporation may be compelled to pay, pending the review proceedings, for transportation, transmission, product, commodity or service in excess of the charges fixed by the rule, regulation, order or decision of the Commission, in case said rule, regulation, order or decision is sustained. However, no bond shall be required in the case of any stay or suspension granted on application of the State or people of the State, represented by the Attorney General or Public Counsel, or of any city or other governmental body. The court in case it stays or suspends the rule, regulation, order or decision of the Commission in any manner affecting rates or other charges or classifications, may in its discretion, also by order direct the public utility affected to pay into court, from time to time thereto to be impounded until the final decision of the case or into some bank or trust company paying interest on deposits, under such conditions as the court may prescribe, all sums of money which it may collect from any corporation or person in excess of the sum such corporation or person would have been compelled to pay if the rule, regulation, order or decision of the Commission had not been stayed or suspended.(d) When any rate or other charge has been in force for any length of time exceeding one year, and that rate or other charge is advanced by the public utility and the order of the Commission reinstates that prior rate or other charge, in whole or in part, no suspending order shall be allowed in any case from the reinstating order pending the final determination of the case in the reviewing court, pending the final determination by such reviewing court.Amended by P.A. 100-0840,§ 10, eff. 8/13/2018.
