When must a government lawyer report a public official's intended or ongoing violation of law within or outside the government organization?

Plain-English summary

The opinion applies Model Rules 1.13(b) and (c) to lawyers representing federal, state, local, and tribal government organizations. Its analysis begins with two threshold questions. The lawyer must be acting in a representational capacity, and the identity of the government client must be determined. The client may be the government as a whole, a branch, or one or more agencies. That determination affects whether a communication stays within the client organization or discloses protected information to a third party.

Rule 1.13(b) applies when the lawyer knows that an organizational constituent is acting, intends to act, or refuses to act in a matter related to the representation in violation of a legal obligation to the organization, or in violation of law that reasonably might be imputed to it, and the conduct is likely to cause substantial injury to the organization. The opinion uses Rule 1.0(f)'s actual-knowledge standard, while noting that knowledge may be inferred from circumstances. Even without actual knowledge sufficient to trigger Rule 1.13(b), the lawyer may raise suspected wrongdoing within the client organization, and other duties may require the lawyer to do so.

For Rule 1.13, the committee construes imputation broadly. An officer's, employee's, or other constituent's action or inaction is imputed to the government organization when that person uses or misuses authority possessed by virtue of a government position. The committee also construes injury broadly because a government client has interests in lawful administration, public trust, and the rule of law beyond financial loss. A constitutional violation or violation of a court order ordinarily causes substantial injury; a minor procedural violation that harms no third party and does not impair the government's reputation or public role may not.

When the Rule 1.13(b) elements are met, the lawyer must proceed as reasonably necessary in the organization's best interest. That will likely require referring the matter to higher authority and, if the response is inadequate, potentially to the highest authority that can act, although the opinion recognizes that this may not always be reasonable or practical in government. Rule 1.13(c) permits, but does not require, disclosure outside the organization only if the highest authority insists on or fails timely and appropriately to address a clear violation of law, the lawyer reasonably believes the violation is reasonably certain to cause substantial injury, and the disclosure is limited to what the lawyer reasonably believes necessary to prevent that injury.

In practice

Under this opinion, the Rule 1.13 analysis turns on the lawyer's representational role, the identity of the government client, actual knowledge, whether the official used or misused governmental authority, and whether the resulting injury to the organization is substantial. Internal reporting ordinarily does not implicate Rule 1.6 when the recipient is within the government client, but the answer depends on who the client is.

The opinion distinguishes mandatory internal action under Rule 1.13(b) from permissive external disclosure under Rule 1.13(c). A subordinate government lawyer remains responsible for complying with the Rules unless a supervisor's direction is a reasonable resolution of an arguable question of professional duty under Rule 5.2(b).

Common questions

Q: Does Rule 1.13 apply to every lawyer employed by a government office?

A: No. The opinion states that Rules governing the lawyer-client relationship apply only when the lawyer serves in a representational capacity. A lawyer working in a nonrepresentational government role may have disclosure duties under statutes, regulations, or internal policy, but not from Rule 1.13 by virtue of that role alone.

Q: Who is the client for a government lawyer?

A: The opinion says the answer may be the government entity as a whole, a branch, or one or more agencies, and that the Model Rules do not resolve the issue. Identifying the client determines whether reporting to another official is an internal client communication or a disclosure to a third party under Rule 1.6.

Q: Must the lawyer have proof of the official's violation before Rule 1.13(b) applies?

A: Rule 1.13(b) uses actual knowledge as defined in Rule 1.0(f), though knowledge may be inferred from circumstances. The opinion adds that a government lawyer may report suspected wrongdoing within the client organization even when the Rule 1.13(b) knowledge threshold has not been met.

Q: When is an official's violation imputed to the government organization?

A: For purposes of Rule 1.13, the opinion concludes that imputation exists when an officer, employee, or other constituent uses or misuses authority possessed by virtue of a government position. The committee limits that construction to Rule 1.13 and does not decide imputation under other law.

Q: What counts as substantial injury to a government client?

A: The lawyer must exercise reasonable professional judgment based on the facts known at the time. The opinion treats constitutional violations, violations of court orders, substantial reputational harm, legal exposure, and interference with a government investigation as examples that may qualify, while a harmless minor procedural violation may not.

Q: When may the lawyer disclose the matter outside the government organization?

A: Rule 1.13(c) permits outside disclosure only after the lawyer's Rule 1.13(b) efforts fail because the highest authority insists on or does not timely and appropriately address a clear violation of law, and the lawyer reasonably believes the violation is reasonably certain to cause substantial injury. Any disclosure is limited to what the lawyer reasonably believes necessary to prevent that injury, and Rule 1.13(d) excludes specified investigation and defense representations.

Background and rules framework

Model Rule 1.13(b) requires an organizational lawyer who knows of qualifying constituent misconduct likely to cause substantial injury to proceed as reasonably necessary in the organization's best interest, ordinarily through referral to higher authority. Model Rule 1.13(c) creates a narrower permission to disclose outside the organization when the highest authority fails to address a clear violation of law reasonably certain to cause substantial injury. Rule 1.13(d) excludes information relating to specified investigation and defense representations from paragraph (c).

The opinion also applies Rule 1.0(f)'s actual-knowledge definition and Rule 1.0(l)'s definition of substantial as a material matter of clear and weighty importance. Rules 1.4 and 2.1 support internal communication and candid advice, Rule 1.6 governs disclosure beyond the client, and Rule 5.2 addresses a subordinate lawyer's responsibility for directions from a supervisor.
