A lawyer having knowledge 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 appropriate professional authority. This Rule does not require disclosure of information otherwise protected by Rule 1.6 or information gained by a lawyer or judge while serving as a member of an approved lawyers assistance program to the extent that such information would be confidential if it were communicated subject to the attorney-client privilege related to the representation of a client .
Lawyers have a similar obligation with respect to judicial misconduct.
An apparently isolated violation may indicate a pattern of misconduct that only a disciplinary investigation can uncover. Reporting of a violation is especially important where the victim is unlikely to discover the offense. A report about misconduct is not 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. Such a requirement existed in many jurisdictions but proved to be unenforceable.
