(a) The appellate authority for any proceedings shall be the official or component that would have jurisdiction over an appeal of the merits.

(b) If either the applicant or the agency's litigating party seeks review of the adjudicative officer's decision on the fee application, it shall file and serve exceptions within 30 days after issuance of the initial decision. Within another 30 days after receipt of such exceptions, the opposing party, if it has not done so previously, may file its own exceptions to the adjudicative officer's decision. The appellate authority shall issue a final decision on the application as soon as possible or remand the application to the adjudicative officer for further proceedings. Any party that does not file and serve exceptions within the stated time limit loses the opportunity to do so.
