The board or its designee may conduct a preliminary investigation of the allegations of any complaint. In conducting such investigation, the board may require the complainant and respondent to furnish evidence, including affidavits and other documents if appropriate. If a review of the evidence shows that the complaint has no basis in fact, the complaint may be dismissed with prejudice by the board and the parties notified. Administrative law judges involved in investigations under this rule shall not act as presiding officers in any proceeding related to the prohibited practice complaint.
