What should a lawyer do if they know another lawyer has committed a violation affecting their honesty?

When a lawyer knows that another attorney has committed a violation that affects their honesty, the appropriate course of action is to report the violation to the appropriate authority. This aligns with the ethical obligations outlined in the ABA Model Rules of Professional Conduct, particularly Rule 8.3, which addresses the reporting of professional misconduct. According to this rule, attorneys have a duty to inform the appropriate professional authority if they know of a violation of the Rules of Professional Conduct that raises a substantial question as to another lawyer's honesty, trustworthiness, or fitness as a lawyer.

Taking this action not only helps uphold the integrity of the legal profession but also protects the public interest and ensures that ethical standards are maintained. It recognizes that the responsibility to the legal system and the clients served outweighs personal or professional considerations, such as maintaining relationships with fellow lawyers.

Other choices, such as ignoring the violation or discussing it informally, would not fulfill the legal obligation to report misconduct, potentially allowing unethical behavior to continue unchecked. Submitting a formal complaint to the Bar Association might be a step following the report, but the initial reporting to the appropriate authority is crucial for addressing the violation effectively and appropriately.
