Any order of the Commission entered hereunder shall be reviewable on petition of any party aggrieved thereby, by the United States Court of Appeals for any circuit in which a hearing was held, or if no hearing was held, any circuit in which the appellee is located, under the procedure provided in sections
9 and
15 of this title. Such appeal shall not be effective unless within 30 days from and after the date of the reparation order the appellant also files with the clerk of the court a bond in double the amount of the reparation awarded against the appellant conditioned upon the payment of the judgment entered by the court, plus interest and costs, including a reasonable attorney’s fee for the appellee, if the appellee shall prevail. Such bond shall be in the form of cash, negotiable securities having a market value at least equivalent to the amount of bond prescribed, or the undertaking of a surety company on the approved list of sureties issued by the Treasury Department of the United States. The appellee shall not be liable for costs in said court. If the appellee prevails, he shall be allowed a reasonable attorney’s fee to be taxed and collected as a part of his costs.
