At least fifteen days' written notice of such a hearing shall be given to the commissioner whose conduct is in question and to all other members of the Authority. At the hearing the commissioner may be represented by counsel and may appear personally and present such pertinent evidence as he wishes or as the presiding officer or his designee may request.
If after a hearing the presiding officer determines that a commissioner has been incompetent or has been guilty of neglect of duty or malfeasance, he shall remove such commissioner from the Authority within seven days, and there shall thereupon be deemed to be a vacancy of such office.
