(a) Any person compelled to submit documentary material, tangible things, or written reports or answers to questions to the Bureau, or to testify in an investigational hearing, shall be entitled to retain a copy or, on payment of lawfully prescribed costs, request a copy of the materials, things, reports, or written answers submitted, or a transcript of his or her testimony. The Bureau, however, may for good cause deny such a request and limit the witness to inspection of the official transcript of the testimony. Upon completion of transcription of the testimony of the witness, the witness shall be offered an opportunity to read the transcript of his or her testimony. Any changes by the witness shall be entered and identified upon the transcript by the Bureau investigator with a statement of the reasons given by the witness for making such changes. The transcript shall then be signed by the witness and submitted to the Bureau unless the witness cannot be found, is ill, waives in writing his or her right to signature, or refuses to sign. If the signed transcript is not submitted to the Bureau within 30 calendar days of the witness being afforded a reasonable opportunity to review it, the Bureau investigator, or the individual transcribing the testimony acting at the Bureau investigator's direction, shall sign the transcript and state on the record the fact of the waiver, illness, absence of the witness, or the refusal to sign, together with any reasons given for the failure to sign.

(b) Any witness compelled to appear in person at an investigational hearing may be accompanied, represented, and advised by counsel as follows:

(1) Counsel for a witness may advise the witness, in confidence and upon the initiative of either counsel or the witness, with respect to any question asked of the witness where it is claimed that a witness is privileged to refuse to answer the question. Counsel may not otherwise consult with the witness while a question directed to the witness is pending.

(2) Any objections made under the rules in this part shall be made only for the purpose of protecting a constitutional or other legal right or privilege, including the privilege against self-incrimination. Neither the witness nor counsel shall otherwise object or refuse to answer any question. Any objection during an investigational hearing shall be stated concisely on the record in a nonargumentative and nonsuggestive manner. Following an objection, the examination shall proceed and the testimony shall be taken, except for testimony requiring the witness to divulge information protected by the claim of privilege or work product.

(3) Counsel for a witness may not, for any purpose or to any extent not allowed by paragraphs (b)(1) and (2) of this section, interrupt the examination of the witness by making any objections or statements on the record. Petitions challenging the Bureau's authority to conduct the investigation or the sufficiency or legality of the civil investigative demand shall be addressed to the Bureau in advance of the hearing in accordance with § 1080.6(e). Copies of such petitions may be filed as part of the record of the investigation with the Bureau investigator conducting the investigational hearing, but no arguments in support thereof will be allowed at the hearing.

(4) Following completion of the examination of a witness, counsel for the witness may, on the record, request that the Bureau investigator conducting the investigational hearing permit the witness to clarify any of his or her answers. The grant or denial of such request shall be within the sole discretion of the Bureau investigator conducting the hearing.

(5) The Bureau investigator conducting the hearing shall take all necessary action to regulate the course of the hearing to avoid delay and to prevent or restrain disorderly, dilatory, obstructionist, or contumacious conduct, or contemptuous language. Such Bureau investigator shall, for reasons stated on the record, immediately report to the Bureau any instances where an attorney has allegedly refused to comply with his or her obligations under the rules in this part, or has allegedly engaged in disorderly, dilatory, obstructionist, or contumacious conduct, or contemptuous language in the course of the hearing. The Bureau will thereupon take such further action, if any, as the circumstances warrant, including actions consistent with those described in 12 CFR 1081.107(c) to suspend or disbar the attorney from further practice before the Bureau or exclude the attorney from further participation in the particular investigation.
