(a) In general. Whenever any person, partnership, corporation, association, or entity fails to comply with any subpoena duly served upon him, the General Counsel may request that the Attorney General seek enforcement of the subpoena in the district court of the United States for any judicial district in which such person resides, is found, or transacts business (or in the case of a person outside the territorial jurisdiction of any district court, the district court for the District of Columbia), and serve upon such person a petition for an order of such court for the enforcement of this part.

(b) Jurisdiction. Whenever any petition is filed in any district court of the United States under this section, such court shall have jurisdiction to hear and determine the matter so presented, and to enter such order or orders as may be required to carry into effect the provisions of this section. Any final order entered shall be subject to appeal under section 1291 of title 28, United States Code. Any disobedience of any final order entered under this section by any court may be punished as contempt.
