(a) A lawyer who knows that another lawyer has committed a violation of the Rules of Professional Conduct that raises a substantial question as to that lawyer’s honesty, trustworthiness or fitness as a lawyer in other respects, shall inform the Bar Counsel’s office of the Board of Bar Overseers. 

(b) A lawyer who knows that a judge has committed a violation of applicable rules of judicial conduct that raises a substantial question as to the judge’s fitness for office shall inform the Commission on Judicial Conduct. 

(c) This Rule does not require disclosure of information otherwise protected by Rule 1.6.

Adopted March 26, 2015, effective July 1, 2015. 


[1] This Rule requires lawyers to report serious violations of ethical duty by lawyers and judges. Even an apparently isolated violation may indicate a pattern of misconduct that only a disciplinary investigation can uncover. Reporting a violation is especially important where the victim is unlikely to discover the offense. 

[2] A report about misconduct is not permitted or required where it would involve violation of Rule 1.6. However, a lawyer should encourage a client to consent to disclosure where prosecution would not substantially prejudice the client’s interests. 

[3] While a measure of judgment is required in complying with the provisions of the Rule, a lawyer must report misconduct that, if proven and without regard to mitigation, would likely result in an order of suspension or disbarment, including misconduct that would constitute a “serious crime” as defined in  S.J.C. Rule 4:01, § 12(3) . Precedent for determining whether an offense would warrant suspension or disbarment may be found in the Massachusetts Attorney Discipline Reports. Section 12(3) of Rule 4:01 provides that a serious crime is “any felony, and … any lesser crime a necessary element of which … includes interference with the administration of justice, false swearing, misrepresentation, fraud, willful failure to file income tax returns, deceit, bribery, extortion, misappropriation, theft, or an attempt or a conspiracy, or solicitation of another to commit [such a crime].” In addition to a conviction of a felony, misappropriation of client funds and perjury before a tribunal are common examples of reportable conduct. The term “substantial” refers to the seriousness of the possible offense and not the quantum of evidence of which the lawyer is aware. A lawyer has knowledge of a violation when he or she possesses supporting evidence such that a reasonable lawyer under the circumstances would form a firm opinion that the conduct in question had more likely occurred than not. A report should be made to Bar Counsel’s office or to the Judicial Conduct Commission, as the case may be. Rule 8.3 does not preclude a lawyer from reporting a violation of the Massachusetts Rules of Professional Conduct in circumstances where a report is not mandatory. 

[3A] In most situations, a lawyer may defer making a report under this Rule until the matter has been concluded, but the report should be made as soon as practicable thereafter. An immediate report is ethically compelled, however, when a client or third person will likely be injured by a delay in reporting, such as where the lawyer has knowledge that another lawyer has embezzled client or fiduciary funds and delay may impair the ability to recover the funds. 

[4] The duty to report past professional misconduct does not apply to a lawyer retained to represent a lawyer whose professional conduct is in question. Such a situation is governed by the Rules applicable to the client-lawyer relationship.
