The Mac Bank Chairman will not be sitting on the panel which makes the decision
When a matter is referred to the Panel, the Panel must consider whether it will commence proceedings in relation to the matter. If it does, the substantive President of the Panel appoints three members to be the "sitting Panel'. If the substantive President is on any particular sitting Panel then he or she will be the sitting President. The substantive President and the selected Panel members must ensure that the selected Panel members do not have any material conflicts or biases.
