Within 30 days after the Chair serves his or her action or decision, or the Commission serves notice of its intent to remove a certificate of self-regulation, the appellant must file a notice of appeal with the Commission. The notice of appeal must reference the action or decision from which the appeal is taken and shall include a written waiver of the right to an oral hearing before a presiding official and an election to have the matter determined by the Commission solely on the basis of written submissions.

The appeal brief shall state succinctly the relief sought and the supporting ground(s) therefor, and may include supporting documentation.
