The Commission may promulgate such rules, regulations, and orders as it deems necessary or appropriate for the efficient and expeditious administration of this section. Notwithstanding any other provision of law, such rules, regulations, and orders may prescribe, or otherwise condition, without limitation, the form, filing, and service of pleadings or orders, the nature and scope of discovery, counterclaims, motion practice (including the grounds for dismissal of any claim or counterclaim), hearings (including the waiver thereof, which may relate to the amount in controversy), rights of appeal, if any, and all other matters governing proceedings before the Commission under this section.

In case a complaint is made by a nonresident of the United States, the complainant shall be required, before any formal action is taken on his complaint, to furnish a bond in double the amount of the claim conditioned upon the payment of costs, including a reasonable attorney’s fee for the respondent if the respondent shall prevail, and any reparation award that may be issued by the Commission against the complainant on any counterclaim by respondent: Provided, That the Commission shall have authority to waive the furnishing of a bond by a complainant who is a resident of a country which permits the filing of a complaint by a resident of the United States without the furnishing of a bond.

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 section 9 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.

Unless the party against whom a reparation order has been issued shows to the satisfaction of the Commission within fifteen days from the expiration of the period allowed for compliance with such order that either an appeal as herein authorized has been taken or payment of the full amount of the order (or any agreed settlement thereof) has been made, such party shall be prohibited automatically from trading on all registered entities and, if the party is registered with the Commission, such registration shall be suspended automatically at the expiration of such fifteen-day period until such party shows to the satisfaction of the Commission that payment of such amount with interest thereon to date of payment has been made: Provided, That if on appeal the appellee prevails or if the appeal is dismissed, the automatic prohibition against trading and suspension of registration shall become effective at the expiration of thirty days from the date of judgment on the appeal, but if the judgment is stayed by a court of competent jurisdiction, the suspension shall become effective ten days after the expiration of such stay, unless prior thereto the judgment of the court has been satisfied.
