If a person is allowed to intervene in the proceeding after the commencement of a hearing under this section, the administrative law judge may prohibit the intervener from recalling any witness who has been heard or reopening any matter that has been resolved, unless the intervener did not receive a notice required by this chapter or the intervener presents facts that demonstrate that fraud, perjury, or an abuse of discretion has occurred. Any proceedings conducted before the giving of a notice required by this chapter are voidable upon the motion of the party who failed to receive the notice.
