In the event the adjudicative officer is not the entire Board, the applicant or agency counsel may seek review of the initial decision on the fee application, or the Board may review the decision on its own initiative, in accordance with § 1115.2. If no appeal is taken, the initial decision becomes the action of the Board 20 days after it is issued. If the adjudicative officer is the entire Board, § 1115.3 applies.
