The attendance of witnesses and the production of documents provided for in this subsection may be required from any place in any State or in any territory or other place subject to the jurisdiction of the United States at any designated place where such proceeding is being conducted. Any party to proceedings under this chapter may apply to the United States District Court for the District of Columbia, or the United States district court for the judicial district or the United States court in any territory in which such proceeding is being conducted or where the witness resides or carries on business, for the enforcement of any subpoena or subpoena duces tecum issued pursuant to this subsection, and such courts shall have jurisdiction and power to order and require compliance therewith. Witnesses subpoenaed under this subsection shall be paid the same fees and mileage that are paid witnesses in the district courts of the United States. Any service required under this subsection may be made by registered mail, or in such other manner reasonably calculated to give actual notice as the Board may by regulation or otherwise provide. Any court having jurisdiction of any proceeding instituted under this subsection may allow to any such party such reasonable expenses and attorneys’ fees as it deems just and proper. Any person who willfully shall fail or refuse to attend and testify or to answer any lawful inquiry or to produce books, papers, correspondence, memoranda, contracts, agreements, or other records, if in such person’s power so to do, in obedience to the subpoena of the Board, shall be guilty of a misdemeanor and, upon conviction, shall be subject to a fine of not more than $1,000 or to imprisonment for a term of not more than one year or both.
