A hearing shall take place no later than one hundred eighty days after the appointment of the hearings examiner except as may be extended by the commission for good cause. All hearings shall be heard before a duly designated hearings examiner. All parties shall be afforded full opportunity to present evidence and argument on all issues involved. The hearing shall be at the time and place set forth in the notice of hearing, but at that time and place may be continued from day to day or adjourned to a later day or to a different place without notice other than the announcement thereof at the hearing. The hearings examiner, if there is no dispute as to the facts involved in a particular matter, may permit the parties to proceed by memoranda of law in lieu of a hearing unless the procedure would unduly burden any party or is otherwise not conducive to the ends of justice.
