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Some portions of the collection may already be severely out of date, so please be cautious in your use of this material.
ABA Model Rules of Professional Conduct
Comment - Rule 3.1
 The advocate has a duty to use legal procedure for the fullest benefit of the client's cause, but also a duty not to abuse legal procedure. The law, both procedural and substantive, establishes the limits within which an advocate may proceed. However, the law is not always clear and never is static. Accordingly, in determining the proper scope of advocacy, account must be taken of the law's ambiguities and potential for change.
 The filing of an action or defense or similar action taken for a client is not frivolous merely because the facts have not first been fully substantiated or because the lawyer expects to develop vital evidence only by discovery. Such action is not frivolous even though the lawyer believes that the client's position ultimately will not prevail. The action is frivolous, however, if the client desires to have the action taken primarily for the purpose of harassing or maliciously injuring a person, or, if the lawyer is unable either to make a good faith argument on the merits of the action taken or to support the action taken by a good faith argument for an extension, modification or reversal of existing law.
Model Code Comparison
DR 7-102(A)(1) provided that a lawyer may not "[f]ile a suit, assert a position, conduct a defense, delay a trial, or take other action on behalf of his client when he knows or when it is obvious that such action would serve merely to harass or maliciously injure another." Rule 3.1 is to the same general effect as DR 7-102(A)(1), with three qualifications. First, the test of improper conduct is changed from "merely to harass or maliciously injure another" to the requirement that there be a basis for the litigation measure involved that is "not frivolous." This includes the concept stated in DR 7-102(A)(2) that a lawyer may advance a claim or defense unwarranted by existing law if "it can be supported by good faith argument for an extension, modification, or reversal of existing law." Second, the test in Rule 3.1 is an objective test, whereas DR 7-102(A)(1) applied only if the lawyer "knows or when it is obvious" that the litigation is frivolous. Third, Rule 3.1 has an exception that in a criminal case, or a case in which incarceration of the client may result (for example, certain juvenile proceedings), the lawyer may put the prosecution to its proof even if there is no nonfrivolous basis for defense.
