In the case of contumacy or refusal to obey a subpoena issued pursuant to this paragraph and served upon any person, the district court of the United States for any district in which such person is found, resides, or transacts business, upon application by the Bureau or a Bureau investigator and after notice to such person, may issue an order requiring such person to appear and give testimony or to appear and produce documents or other material.
A verified return by the individual serving any civil investigative demand or any enforcement petition filed under this section setting forth the manner of such service shall be proof of such service.
In the case of service by registered or certified mail, such return shall be accompanied by the return post office receipt of delivery of such demand or enforcement petition.
The production of documentary material in response to a civil investigative demand shall be made under a sworn certificate, in such form as the demand designates, by the person, if a natural person, to whom the demand is directed or, if not a natural person, by any person having knowledge of the facts and circumstances relating to such production, to the effect that all of the documentary material required by the demand and in the possession, custody, or control of the person to whom the demand is directed has been produced and made available to the custodian.
The submission of tangible things in response to a civil investigative demand shall be made under a sworn certificate, in such form as the demand designates, by the person to whom the demand is directed or, if not a natural person, by any person having knowledge of the facts and circumstances relating to such production, to the effect that all of the tangible things required by the demand and in the possession, custody, or control of the person to whom the demand is directed have been submitted to the custodian.
Each reporting requirement or question in a civil investigative demand shall be answered separately and fully in writing under oath, unless it is objected to, in which event the reasons for the objection shall be stated in lieu of an answer, and it shall be submitted under a sworn certificate, in such form as the demand designates, by the person, if a natural person, to whom the demand is directed or, if not a natural person, by any person responsible for answering each reporting requirement or question, to the effect that all information required by the demand and in the possession, custody, control, or knowledge of the person to whom the demand is directed has been submitted.
The examination of any person pursuant to a demand for oral testimony served under this subsection shall be taken before an officer authorized to administer oaths and affirmations by the laws of the United States or of the place at which the examination is held. The officer before whom oral testimony is to be taken shall put the witness on oath or affirmation and shall personally, or by any individual acting under the direction of and in the presence of the officer, record the testimony of the witness.
Any Bureau investigator before whom oral testimony is to be taken shall exclude from the place where the testimony is to be taken all other persons, except the person giving the testimony, the attorney for that person, the officer before whom the testimony is to be taken, an investigator or representative of an agency with which the Bureau is engaged in a joint investigation, and any stenographer taking such testimony.
The oral testimony of any person taken pursuant to a civil investigative demand shall be taken in the judicial district of the United States in which such person resides, is found, or transacts business, or in such other place as may be agreed upon by the Bureau investigator before whom the oral testimony of such person is to be taken and such person.
A person described in clause (i), or the attorney for that person, may object on the record to any question, in whole or in part, and such person shall briefly state for the record the reason for the objection. An objection may properly be made, received, and entered upon the record when it is claimed that such person is entitled to refuse to answer the question on grounds of any constitutional or other legal right or privilege, including the privilege against self-incrimination, but such person shall not otherwise object to or refuse to answer any question, and such person or attorney shall not otherwise interrupt the oral examination.
The Bureau investigator shall certify on the transcript that the witness was duly sworn by him or her and that the transcript is a true record of the testimony given by the witness, and the Bureau investigator shall promptly deliver the transcript or send it by registered or certified mail to the custodian.
Documentary materials and tangible things received as a result of a civil investigative demand shall be subject to requirements and procedures regarding confidentiality, in accordance with rules established by the Bureau.
No rule established by the Bureau regarding the confidentiality of materials submitted to, or otherwise obtained by, the Bureau shall be intended to prevent disclosure to either House of Congress or to an appropriate committee of the Congress, except that the Bureau is permitted to adopt rules allowing prior notice to any party that owns or otherwise provided the material to the Bureau and had designated such material as confidential.
Whenever any person fails to comply with any civil investigative demand duly served upon him under this section, or whenever satisfactory copying or reproduction of material requested pursuant to the demand cannot be accomplished and such person refuses to surrender such material, the Bureau, through such officers or attorneys as it may designate, may file, in the district court of the United States for any judicial district in which such person resides, is found, or transacts business, and serve upon such person, a petition for an order of such court for the enforcement of this section.
Not later than 20 days after the service of any civil investigative demand upon any person under subsection (b), or at any time before the return date specified in the demand, whichever period is shorter, or within such period exceeding 20 days after service or in excess of such return date as may be prescribed in writing, subsequent to service, by any Bureau investigator named in the demand, such person may file with the Bureau a petition for an order by the Bureau modifying or setting aside the demand.
The time permitted for compliance with the demand in whole or in part, as determined proper and ordered by the Bureau, shall not run during the pendency of a petition under paragraph (1) at the Bureau, except that such person shall comply with any portions of the demand not sought to be modified or set aside.
At any time during which any custodian is in custody or control of any documentary material, tangible things, reports, answers to questions, or transcripts of oral testimony given by any person in compliance with any civil investigative demand, such person may file, in the district court of the United States for the judicial district within which the office of such custodian is situated, and serve upon such custodian, a petition for an order of such court requiring the performance by such custodian of any duty imposed upon him by this section or rule promulgated by the Bureau.
Any final order entered as described in paragraph (1) shall be subject to appeal pursuant to section 1291 of title 28.
