If a timely reply to the appeal is not filed, the presiding officer shall refer the appeal to the Judicial Officer, who may find that the General Counsel or the Chief Postal Inspector or his or her designee is in default. Whenever the General Counsel or the Chief Postal Inspector or his or her designee has been deemed to be in default, the Judicial Officer shall take whatever action on the appeal he deems appropriate. If an oral evidentiary hearing is to be held, the appellant may appear at the hearing in person or by counsel. If either party fails to appear at the hearing, the presiding officer shall receive the evidence of the party appearing and render a decision.
