In a proceeding before the Board, any person or party may appear on his or her own behalf.
Any person or party may be represented by any other person duly authorized in writing to do so.
The authorization shall be on a form prescribed by the Board and shall state either that the individual is an attorney duly licensed to practice law in the District, or if not an attorney, that the authorization includes the power of the agent or representative to bind the person in the matter before the Board.
If any person or party waives the right to be present at a hearing or fails to appear at a hearing, the Board may proceed ex parte, unless the Board extends the time of the hearing or unless the person's appearance is required by statute.
