In carrying out section 42101 of this title, the Federal Maritime Commission may order any person (including a common carrier, tramp operator, bulk operator, shipper, shippers’ association, ocean transportation intermediary, or marine terminal operator, or an officer, receiver, trustee, lessee, agent, or employee thereof) to file with the Commission a report, answers to questions, documentary material, or other information the Commission considers necessary or appropriate. The Commission may require the response to any such order to be made under oath. The response shall be provided in the form and within the time specified by the Commission.

Unless otherwise prohibited by law, and subject to funds being appropriated, a witness in a proceeding under section 42101 of this title is entitled to the same fees and mileage as in the courts of the United States.

If a person does not comply with an order or subpoena of the Commission under this section, the Commission may seek enforcement in a district court of the United States having jurisdiction over the parties. If, after hearing, the court determines that the order or subpoena was regularly made and duly issued, the court shall enforce the order or subpoena.
