Enforcement Rule 209(a) provides that complaints submitted to the Executive Office or to the Office of Disciplinary Counsel shall be confidential. Unless and until formal charges are filed and the complainant is designated as a witness at the prehearing conference, or Disciplinary Counsel determines that the complaint contains exculpatory material, the complaint shall not be provided to the respondent-attorney. At or after the prehearing conference, the senior or experienced hearing committee member may enter a protective order on cause shown to prohibit disclosure of the complaint or parts of it to the public.
