(1) Any party in interest, being dissatisfied with the order of the commission fixing any rate, fare, charge, classification, or joint rate or any order fixing or prescribing any rule, practice, or service, may apply to the district court having jurisdiction for an injunction, staying and suspending the operation of the order of the commission pending the final determination of the reasonableness and lawfulness of said order in the courts. Upon proper showing an injunction shall be issued by such court.
(2) As a condition to the granting of such injunction, the court shall require of the party seeking such injunction an undertaking entered into on the part of the plaintiff, supported by responsible corporate surety, in such reasonable sum as the court shall direct, to the effect that the plaintiff will pay all damages which the opposite party may sustain by reason of the delay or prevention of the order of the commission becoming effective if said order is sustained in the final determination, or in proceedings involving rates, the court may in the alternative require the difference between the existing rate and the commission ordered rate to be impounded under the direction of the court, pending the final determination of the action.
