Comment

Paragraph (a) – Duties Of Managerial Lawyers To Reasonably* Assure Compliance with the Rules

[1] Paragraph (a) requires lawyers with managerial authority within a law firm* to make reasonable* efforts to establish internal policies and procedures designed, for example, to detect and resolve conflicts of interest, identify dates by which actions must be taken in pending matters, account for client funds and property, and ensure that inexperienced lawyers are properly supervised.

[2] Whether particular measures or efforts satisfy the requirements of paragraph (a) might depend upon the law firm’s structure and the nature of its practice, including the size of the law firm,* whether it has more than one office location or practices in more than one jurisdiction, or whether the firm* or its partners* engage in any ancillary business.

[3] A partner,* shareholder or other lawyer in a law firm* who has intermediate managerial responsibilities satisfies paragraph (a) if the law firm* has a designated managing lawyer charged with that responsibility, or a management committee or other body that has appropriate managerial authority and is charged with that responsibility. For example, the managing lawyer of an office of a multi-office law firm* would not necessarily be required to promulgate firm-wide policies intended to reasonably* assure that the law firm’s lawyers comply with the rules or State Bar Act. However, a lawyer remains responsible to take corrective steps if the lawyer knows* or reasonably should know* that the delegated body or person* is not providing or implementing measures as required by this rule.

[4] Paragraph (a) also requires managerial lawyers to make reasonable* efforts to assure that other lawyers in an agency or department comply with these rules and the State Bar Act. This rule contemplates, for example, the creation and implementation of reasonable* guidelines relating to the assignment of cases and the distribution of workload among lawyers in a public sector legal agency or other legal department. (See, e.g., State Bar of California, Guidelines on Indigent Defense Services Delivery Systems (2006).)

Paragraph (b) – Duties of Supervisory Lawyers

[5] Whether a lawyer has direct supervisory authority over another lawyer in particular circumstances is a question of fact.

Paragraph (c) – Responsibility for Another’s Lawyer’s Violation

[6] The appropriateness of remedial action under paragraph (c)(2) would depend on the nature and seriousness of the misconduct and the nature and immediacy of its harm. A managerial or supervisory lawyer must intervene to prevent avoidable consequences of misconduct if the lawyer knows* that the misconduct occurred.

[7] A supervisory lawyer violates paragraph (b) by failing to make the efforts required under that paragraph, even if the lawyer does not violate paragraph (c) by knowingly* directing or ratifying the conduct, or where feasible, failing to take reasonable* remedial action.

[8] Paragraphs (a), (b), and (c) create independent bases for discipline. This rule does not impose vicarious responsibility on a lawyer for the acts of another lawyer who is in or outside the law firm.* Apart from paragraph (c) of this rule and rule 8.4(a), a lawyer does not have disciplinary liability for the conduct of a partner,* associate, or subordinate lawyer. The question of whether a lawyer can be liable civilly or criminally for another lawyer’s conduct is beyond the scope of these rules.
