1 Pa. Code § 35.114
The presiding officer at a conference may dispose of by ruling, irrespective of the consent of the participants, procedural matters which he is authorized to rule upon during the course of the proceeding, and which it appears may appropriately and usefully be disposed of at that stage. In addition, if it appears that the proceeding would be substantially expedited by distribution of proposed exhibits and written prepared testimony reasonably in advance of the hearing session, the presiding officer at his discretion and with due regard for the convenience and necessity of the parties, the staff of the agency and staff counsel, may direct the advance distribution by a prescribed date. The rulings of the presiding officer made at the conference shall control the subsequent course of the hearing, unless modified for good cause shown.
