End-of-life notice: American Legal Ethics Library
As of March 1, 2013, the Legal Information Institute is no longer maintaining the information in the American Legal Ethics Library. It is no longer possible for us to maintain it at a level of completeness and accuracy given its staffing needs. It is very possible that we will revive it at a future time. At this point, it is in need of a complete technological renovation and reworking of the "correspondent firm" model which successfully sustained it for many years.
Many people have contributed time and effort to the project over the years, and we would like to thank them. In particular, Roger Cramton and Peter Martin not only conceived ALEL but gave much of their own labor to it. We are also grateful to Brad Wendel for his editorial contributions, to Brian Toohey and all at Jones Day for their efforts, and to all of our correspondents and contributors. Thank you.
We regret any inconvenience.
Some portions of the collection may already be severely out of date, so please be cautious in your use of this material.
Arizona Rules of Professional Conduct
Comment - ER 5.1
 Paragraph (a) applies to lawyers who have managerial authority over the professional work of a firm. See ER 1.0(c). This includes members of a partnership, the shareholders in a law firm organized as a professional corporation, and members of other associations authorized to practice law; lawyers having comparable managerial authority in a legal services organization or a law department of an enterprise or government agency; and lawyers who have intermediate managerial responsibilities in a firm. Paragraph (b) applies to lawyers who have supervisory authority over the work of other lawyers in a firm.
 Paragraph (a) requires lawyers with managerial authority within a firm to make reasonable efforts to establish internal policies and procedures designed to provide reasonable assurance that all lawyers in the firm will conform to the Rules of Professional Conduct. Such policies and procedures include those designed 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.
 Other measures that may be required to fulfill the responsibility prescribed in paragraph (a) can depend on the firm's structure and the nature of its practice. In a small firm of experienced lawyers, informal supervision and periodic review of compliance with the required systems ordinarily will suffice. In a large firm, or in practice situations in which difficult ethical problems frequently arise, more elaborate measures may be necessary. Some firms, for example, have a procedure whereby junior lawyers can make confidential referral of ethical problems directly to a designated senior partner or special committee. See ER 5.2. Firms, whether large or small, may also rely on continuing legal education in professional ethics. In any event, the ethical atmosphere of a firm can influence the conduct of all its members the partners may not assume that all lawyers associated with the firm will inevitably conform to the Rules.
 Paragraph (c) expresses a general principle of personal responsibility for acts of another. See also ER 8.4(a).
 Paragraph (c)(2) defines the duty of a partner or other lawyer having comparable managerial authority in a law firm, as well as a lawyer who has direct supervisory authority over performance of specific legal work by another lawyer. Whether a lawyer has supervisory authority in particular circumstances is a question of fact. Partners and lawyers with comparable authority have at least indirect responsibility for all work being done by the firm, while a partner or manager in charge of a particular matter ordinarily also has supervisory responsibility for the work of other firm lawyers engaged in the matter. Appropriate remedial action by a partner or managing lawyer would depend on the immediacy of that lawyer's involvement and the seriousness of the misconduct. A supervisor is required to intervene to prevent avoidable consequences of misconduct if the supervisor knows that the misconduct occurred. Thus, if a supervising lawyer knows that a subordinate misrepresented a matter to an opposing party in negotiation, the supervisor as well as the subordinate has a duty to correct the resulting misapprehension.
 Professional misconduct by a lawyer under supervision could reveal a violation of paragraph (b) on the part of the supervisory lawyer even though it does not entail a violation of paragraph (c) because there was no direction, ratification or knowledge of the violation.
 Apart from this Rule and ER 8.4(a), a lawyer does not have disciplinary liability for the conduct of a partner, associate or subordinate. Whether a lawyer may be liable civilly or criminally for another lawyer's conduct is a question of law beyond the scope of these Rules.
