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Some portions of the collection may already be severely out of date, so please be cautious in your use of this material.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 1.3
 A lawyer should pursue a matter on behalf of a client despite opposition, obstruction or personal inconvenience to the lawyer, and take whatever lawful and ethical measures are required to vindicate a client's cause or endeavor. A lawyer must also act with commitment and dedication to the interests of the client and with zeal in advocacy upon the client's behalf. A lawyer is not bound, however, to press for every advantage that might be realized for a client. For example, a lawyer may have authority to exercise professional discretion in determining the means by which a matter should be pursued. See ER 1.2. The lawyer's duty to act with reasonable diligence does not require the use of offensive tactics or preclude the treating of all persons involved in the legal process with courtesy and respect.

shortcoming is more widely resented than procrastination. A client's interests
often can be adversely affected by the passage of time or the change of conditions;
in extreme instances, as when a lawyer overlooks a statute of limitations,
the client's legal position may be destroyed. Even when the client's interests
are not affected in substance, however, unreasonable delay can cause a client
needless anxiety and undermine confidence in the lawyer's trustworthiness.
A lawyer's duty to act with reasonable
promptness, however, does not preclude the lawyer from agreeing to a
 Unless the relationship is terminated as provided in ER 1.16, a lawyer should carry through to conclusion all matters undertaken for a client. If a lawyer's employment is limited to a specific matter, the relationship terminates when the matter has been resolved. If a lawyer has served a client over a substantial period in a variety of matters, the client sometimes may assume that the lawyer will continue to serve on a continuing basis unless the lawyer gives notice of withdrawal. Doubt about whether a client-lawyer relationship still exists should be clarified by the lawyer, preferably in writing, so that the client will not mistakenly suppose the lawyer is looking after the client's affairs when the lawyer has ceased to do so. For example, if a lawyer has handled a judicial or administrative proceeding that produced a result adverse to the client and the lawyer and the client have not agreed that the lawyer will handle the matter on appeal, the lawyer must consult with the client about the possibility of appeal before relinquishing responsibility for the matter. See ER 1.4(a)(2). Whether the lawyer is obligated to prosecute the appeal for the client depends on the scope of the representation the lawyer has agreed to provide to the client. See ER 1.2.
