Hearings provided by this section are not subject to the adjudicative provisions of the Administrative Procedure Act (5 U.S.C. 554-557). The presiding officer is, however, authorized to exercise all of the powers enumerated in § 109.5 of this chapter.

Witnesses may be presented, within time limits specified by the presiding officer, provided that at least 10 days prior to the hearing date, the party presenting the witnesses furnishes the presiding officer and the opposing party with a list of such witnesses and a summary of the proposed testimony. However, the requirement for furnishing such a witness list and summary of testimony shall not apply to the presentation of rebuttal witnesses. The presiding officer may ask questions of any witness, and each party shall have an opportunity to cross-examine any witness presented by an opposing party.

Upon the request of either the petitioner or a representative of the Enforcement and Compliance Division, the record shall remain open for a period of 5 business days following the hearing, during which time the parties may make any additional submissions for the record. Thereafter, the record shall be closed.

Following the introduction of all evidence, the petitioner and the representative of the Enforcement and Compliance Division shall have an opportunity for oral argument; however, the parties may jointly waive the right to oral argument, and, in lieu thereof, elect to submit written argument.

All oral testimony and oral argument shall be recorded, and transcripts made available to the petitioner upon payment of the cost thereof. A copy of the transcript shall be sent directly to the presiding officer, who shall have authority to correct the record sua sponte or upon the motion of any party.

The parties may, in writing, jointly waive an oral hearing and instead elect a hearing upon a written record in which all evidence and argument would be submitted to the presiding officer in documentary form and statements of individuals would be made by affidavit.
