For the purpose of conducting an investigation under this chapter, the department shall subpoena witnesses, take evidence, and require the production of any documents or records that the board considers relevant to the inquiry. The department shall administer oaths and issue subpoenas for the attendance and testimony of witnesses and the production and examination of books, papers, and records on behalf of the board or, upon request, on behalf of a party to a proceeding. Upon failure to obey a subpoena or to answer questions propounded by the board or its hearing officer or panel, the board may apply to an administrative law judge for an order requiring the person to comply. If a board member files a complaint, the board member must not participate in the capacity as a board member at the hearing of the complaint.
