(a) If the Commission determines that evidence or testimony at any hearing may tend to defame, degrade, or incriminate any person, it shall receive such evidence or testimony or summary of such evidence or testimony in executive session.

(b) The Commission shall afford any persons defamed, degraded, or incriminated by such evidence or testimony an opportunity to appear and be heard in executive session, with a reasonable number of additional witnesses requested by them, before deciding to use such evidence or testimony.

(1) Such person shall be served with notice, in writing, at least 10 days prior to the date, time, and location for the appearance of witnesses at executive session or where service is by mail at least 14 days prior to such date. This notice shall be accompanied by a copy of the rules in this part and by a brief summary of the information that the Commission has determined may tend to defame, degrade, or incriminate such person;

(2) The notice, summary, and rules in this part shall be served by certified mail or by leaving a copy thereof at the last known residence or business address of such person; and

(3) The date of service, for purposes of this section, shall be the day when the material is deposited in the mail or is delivered in person, whichever is applicable. When service is made by mail, the return post office receipt shall be proof of service; in all other cases, the acknowledgment of the party served or the verified return of the one making service shall be proof of the same.

(c) If a person receiving notice under this section notifies the Commission within five days of service of such notice or where service is by mail within eight days of service of such notice that the scheduled appearance constitutes a hardship, the Commission may, in its discretion, set a new date or time for such person's appearance at the executive session.

(d) In the event such persons fail to appear at executive session at the time and location scheduled under paragraph (b) or (c) of this section, they shall not be entitled to another opportunity to appear at executive session, except as provided in § 702.11.

(e) If such persons intend to submit sworn statements of themselves or others, or if they intend that witnesses appear in their behalf at executive session, they shall, no later than 48 hours prior to the time set under paragraph (b) or (c) of this section, submit to the Commission all such statements and a list of all witnesses. The Commission will inform such persons whether the number of witnesses requested is reasonable within the meaning of paragraph (b) of this section. In addition, the Commission will receive and dispose of requests from such persons to subpoena other witnesses. Requests for subpoenas shall be made sufficiently in advance of the scheduled executive session to afford subpoenaed persons reasonable notice of their obligation to appear at that session. Subpoenas returnable at executive session shall be governed by the provisions of § 702.4.

(f) Persons for whom an executive session has been scheduled, and persons compelled to appear at such session, may be represented by counsel at such session to the extent provided by § 702.7.

(g) Attendance at executive session shall be limited to Commissioners; authorized Commission staff personnel; witnesses, and their counsel at the time scheduled for their appearance; and such other persons whose presence is requested or consented to by the Commission.

(h) In the event the Commission determines to release or to use evidence or testimony that it has determined may tend to defame, degrade, or incriminate any persons in such a manner as to reveal publicly their identity, such evidence or testimony, prior to such public release or use, will be presented at a public session, and the Commission will afford them an opportunity to appear as voluntary witnesses or to file a sworn statement in their own behalf and to submit brief and pertinent sworn statements of others.
