(a) The administrative law judge may, in his discretion, on his own motion or motion of one of the parties or of the Bureau or Office direct the parties or their representatives to appear at a specified time and place for a prehearing conference to consider: (1) The possibility of obtaining stipulations, admissions of facts and agreements to the introduction of documents, (2) the limitation of the number of expert witnesses, and (3) any other matters which may aid in the disposition of the proceedings.
(b) The administrative law judge shall issue an order which recites the action taken at the conference and the agreements made as to any of the matters considered, and which limits the issues for hearing to those not disposed of by admissions or agreements. Such order shall control the subsequent course of the proceeding before the administrative law judge unless modified for good cause, by subsequent order.
