(a) Requests. Requests for oral hearings in matters originally assigned for handling under modified procedure must include the reasons why the matter cannot be properly resolved under modified procedure. Requests for cross examination of witnesses must include the name of the witness and the subject matter of the desired cross examination.

(b) Disposition. Unless material facts are in dispute, oral hearings will not be held. If held, oral hearings will normally be confined to material issues upon which the parties disagree. The decision setting a matter for oral hearing will define the scope of the hearing.
