What should a lawyer do if they learn of another lawyer's unethical behavior?

When a lawyer becomes aware of another lawyer's unethical behavior, the appropriate course of action is to report it to the appropriate authority. This obligation is rooted in the legal profession's commitment to uphold integrity, protect the public, and maintain ethical standards within the practice of law. Reporting such behavior ensures that misconduct can be addressed and proper disciplinary measures can be taken by the appropriate regulatory body, such as a state bar association.

Lawyers are not just responsible for their own ethical behavior but also have a duty to act when they observe violations by their peers. Such action upholds the rule of law and fosters trust in the legal profession, reaffirming that ethical misconduct will not be tolerated.

While discussing the behavior with the lawyer in question may seem like an option, it does not fulfill the obligation to report and might lead to an inadequate resolution of the issue. Ignoring the behavior could further perpetuate unethical practices and harm clients or the justice system as a whole. Making a public statement could have reputational implications for both the lawyers involved and could violate confidentiality rules. Thus, reporting to the appropriate authority is the necessary and responsible action to take in response to unethical behavior.
