Formal hearing before the board will be scheduled the first Friday following the expiration of 14 days from the date of prehearing conference. If the Friday upon which a hearing would otherwise be scheduled is a legal holiday or follows a legal holiday, the hearing will be scheduled for the following Monday. A claimant or his attorney must give the board and all parties seven days written notice if they intend to be present for such formal hearing. Hearings will begin at 9:30 a.m. in the board's Austin office and cases normally will be heard by the board in the order registered with the receptionist (1970) (Rev. 1977).
