(a)
In appeals where the panel finds that there is relevant evidence which, in the exercise of reasonable diligence, could not have been produced or which was improperly excluded at the hearing before the bureau or licensing authority, it may enter an order remanding the matter to the bureau or licensing authority for reconsideration in the light of such evidence.
(b)
Except as provided in subdivision (a), in all appeals, the panel shall enter an order either affirming or reversing the decision of the bureau or licensing authority. When the order reverses the decision of the bureau or licensing authority, the board may direct the reconsideration of the matter in the light of its order and may direct the bureau or licensing authority to take
such further action as is specially enjoined upon it by law, but the order shall not limit or control in any way the discretion vested by law in the bureau or licensing authority.
