A complaint shall: be in writing; and state specifically the facts on which the complaint is based. If a complaint is made by any person other than the Commission, the complaint shall be made under oath by the person who submits the complaint. A complaint may be accompanied by documentary or other evidence. The Commission shall investigate each complaint submitted to the Commission if the complaint: alleges facts that establish a prima facie case that is grounds for disciplinary action under § 16–701, § 16–701.1, or § 16–701.2 of this title; and meets the requirements of this section. On conclusion of the investigation, the Commission shall determine if there is a reasonable basis to believe that there are grounds for disciplinary action under § 16–701, § 16–701.1, or § 16–701.2 of this title against an applicant or licensee. If the Commission finds a reasonable basis as provided under paragraph (1) of this subsection, the Commission shall act on the complaint as provided under § 16–602 of this subtitle. If the Commission does not find a reasonable basis as provided under paragraph (1) of this subsection, the Commission shall dismiss the complaint.
