At any point during the course of investigation or inquiry into a complaint, the Board or Complaint Committee may determine that there is not and will not be sufficient evidence to warrant further proceedings or that the complaint fails to allege misconduct for which a licensee may be sanctioned by the Board. In such event, the Board may dismiss or close its investigation of the complaint and otherwise communicate with the licensee and/or the complainant, as deemed appropriate by the Board.
