Section 6. (1) Except as provided in this section, all proceedings of the commission shall be confidential until there has been a determination of sufficient cause and formal charges have been filed with the supreme judicial court. The commission shall ensure that a procedure applicable to commission members, counsel and staff is established for enforcing confidentiality.

(2) Notwithstanding the provisions of subdivision (1), the judge may waive his right to confidentiality prior to a finding of sufficient cause. In addition, in any case in which the subject matter becomes public, through independent sources or through a waiver of confidentiality by the judge, the commission may issue such statements as it deems appropriate in order to confirm the pendency of the investigation, to clarify the procedural aspects of the disciplinary proceedings, to explain the right of the judge to a fair hearing without prejudgment, or to state that the judge denies the allegations.

(3) If the inquiry was initiated as a result of notoriety or because of conduct that is a matter of public record, and is subsequently terminated because there is insufficient cause to proceed, information concerning the insufficiency of cause to proceed may be released by the commission.

(4) Notwithstanding any other provision of this chapter to the contrary, proceedings pursuant to this chapter may remain confidential, even after a finding of sufficient cause, if the judge, the commission, and the complainant, if any, all concur.

(5) If any federal agency, the judicial nominating council, or any like agency for screening candidates for judicial appointment which succeeds the judicial nominating council, seeks information or written materials from the commission concerning a judge, in connection with his selection or appointment as a judge, information may be divulged in accordance with procedures prescribed by commission rule, including reasonable notice to the judge affected, unless the judge signs a waiver of the right to such notice. If, in connection with the assignment of a retired judge to judicial duties, the chief justice of the supreme judicial court or the appeals court or the chief justice of the trial court seeks information or written materials from the commission about the judge, information may be divulged in accordance with procedures prescribed by commission rule, including reasonable notice to the judge affected, unless the judge signs a waiver of the right to such notice.
