Section 203.7 - Rights of witnesses(a) Any person who is compelled or requested to furnish documentary evidence or testimony at a formal investigative proceeding shall, upon request, be shown the Commission's order of investigation. Copies of formal orders of investigation shall not be furnished, for their retention, to such persons requesting the same except with the express approval of officials in the Regional Offices at the level of Assistant Regional Director or higher, or officials in the Division or Divisions conducting or supervising the investigation at the level of Assistant Director or higher. Such approval shall not be given unless the person granting such approval, in his or her discretion, is satisfied that there exist reasons consistent both with the protection of privacy of persons involved in the investigation and with the unimpeded conduct of the investigation.(b) Any person compelled to appear, or who appears by request or permission of the Commission, in person at a formal investigative proceeding may be accompanied, represented and advised by counsel, as defined in § 201.101(a) of this chapter (Rule 101(a) of the Commission's rules of practice): Provided, however, That all witnesses shall be sequestered, and unless permitted in the discretion of the officer conducting the investigation no witness or the counsel accompanying any such witness shall be permitted to be present during the examination of any other witness called in such proceeding.(c) The right to be accompanied, represented and advised by counsel shall mean the right of a person testifying to have an attorney present with him during any formal investigative proceeding and to have this attorney(1) advise such person before, during and after the conclusion of such examination,(2) question such person briefly at the conclusion of the examination to clarify any of the answers such person has given, and(3) make summary notes during such examination solely for the use of such person.(d) Unless otherwise ordered by the Commission, in any public formal investigative proceeding, if the record shall contain implications of wrongdoing by any person, such person shall have the right to appear on the record; and in addition to the rights afforded other witnesses hereby, he shall have a reasonable opportunity of cross-examination and production of rebuttal testimony or documentary evidence. Reasonable shall mean permitting persons as full an opportunity to assert their position as may be granted consistent with administrative efficiency and with avoidance of undue delay. The determination of reasonableness in each instance shall be made in the discretion of the officer conducting the investigation.(e) The officer conducting the investigation may report to the Commission any instances where any witness or counsel has been guilty of dilatory, obstructionist or contumacious conduct during the course of an investigation or any other instance of violation of these rules. The Commission will thereupon take such further action as the circumstances may warrant, including suspension or disbarment of counsel from further appearance or practice before it, in accordance with § 201.102(e) of this chapter (Rule 102(e) of the Commission's rules of practice), or exclusion from further participation in the particular investigation.29 FR 3620, Mar. 21, 1964, as amended at 52 FR 12148, Apr. 15, 1987; 59 FR 5945, Feb. 9, 1994; 60 FR 32823, June 23, 1995; 73 FR 32227 , June 5, 2008
