For the purpose of hearing the testimony of witnesses and receiving documents and other data relating to any subject under investigation, the Secretary, or the Secretary's designee, may conduct an investigational proceeding.
The Secretary, or the Secretary's designee, (“presiding official”) shall preside over the investigational proceeding. The proceeding shall be stenographically or mechanically reported. A transcript shall be a part of the record of the investigation.
Unless the presiding official determines otherwise, investigational proceedings shall be public.
The presiding official shall take all necessary action to regulate the course of the proceeding to avoid delay and to maintain order. If necessary to maintain order, the presiding official may exclude a witness or counsel from a proceeding. The Department may also take further action as permitted by statute.
