What I understand is that officials are part of the board, which is the first level within the board. Then there's an appeal, again within the board.
However, the processes of appointing officials to the first level and to the Appeal Division are different. The officials are appointed under the Public Service Employment Act and the members of the Appeal Division are appointed by Cabinet. So the procedure I was proposing earlier would apply to the Appeal Division. As for the officials, they are appointed under the Public Service Employment Act.
