In hearings on complaints, applications, and petitions, the party that shall open and close the presentation of any part of the matter shall be the complainant, applicant, or petitioner. In a case where the opening portion has already been submitted in written form as provided by these rules, the hearing shall open with the cross examination of persons who have given written testimony. In the event any person has given written testimony and is not available for such cross examination at the time and place directed by the commissioners, all of such written testimony may be discarded and removed from the record at the direction of the commissioners.
