Designated officer of AIMR and hearing panel

what happen is A violate CFA code, and designated officer first offer a sanction, but A denied and ask for a hearing. after the hearing, the hearing panel decide to revok A’s CFA title forever. in this case, can A argue that the final decision is severe than the first offer, and request a review? Can the hearing panel deny his request by the reason because A denied first offer, so the decision is final? Thanks.
