Request for postponement.

1. Any request for the postponement of a scheduled hearing must be in writing and signed by the parties or their counsel. The request must include a statement of the reasons for the requested postponement and must be filed with the Board at least 14 days before the time the hearing is scheduled unless good cause is shown to excuse the untimely filing of the request. Except as otherwise provided in subsection 2, the Board will not grant a request for postponement submitted within 30 days after the running of the 180-day period for hearing a complaint. 2. The parties may file with the Commissioner a request to waive the period for hearing a complaint. If the Commissioner grants such a request, the Commissioner may grant a request for postponement submitted after the running of the period for hearing a complaint.
