The public utility whose schedules shall have been so filed or the Commonwealth or other party in interest or party aggrieved may appeal to the Supreme Court from such decision or order as the Commission may finally enter. Upon the granting of such appeal the Supreme Court may award or refuse a writ of supersedeas, and, if a writ of supersedeas be awarded, it may suspend the operation of the action appealed from in whole or in part. Alternatively, the Supreme Court in its discretion may authorize putting into effect the schedule of rates so filed and suspended by the Commission or the schedule of rates existing at the time of the filing of the schedule upon which the investigation and hearing have been had, or require the inauguration of the schedule of rates as ordered by the Commission, until the final disposition of the appeal. But, prior to the final reversal of the order appealed from by the Supreme Court, no action of the Commission prescribing or affecting rates or charges shall be delayed, or suspended in its operation, by reason of any appeal by the party whose rates or charges are affected, or by reason of any proceeding resulting from such appeal until a suspending bond payable to the Commonwealth has been executed and filed with the Commission with such conditions, in such penalty, and with such surety thereon as the Commission, subject to review by the Supreme Court, may deem sufficient. In any appeal from action of the Commission prescribing or affecting the rates or charges of a public utility, such bond, or if no bond is required, the order of the Supreme Court, shall expressly provide for the prompt refunding to the parties entitled thereto of all charges which may have been collected or received, pending the appeal, in excess of those fixed, or authorized by the final decision on appeal, with interest from the date of the collection thereof. But no bond shall be required of the Commonwealth. Any bond required under this section shall be enforced in the name of the Commonwealth before the Commission or before any court having jurisdiction, and the process and proceedings thereon shall be as provided by law upon bonds of like character required to be taken by courts of record of this State.
