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Some portions of the collection may already be severely out of date, so please be cautious in your use of this material.
Pennsylvania Disciplinary Rules of Professional Conduct
Comment - Rule 1.12
 This Rule generally parallels Rule 1.11. The term "personally and substantially" signifies that a judge who was a member of a multi-member court, and thereafter left judicial office to practice law, is not prohibited from representing a client in a matter pending in the court, but in which the former judge did not participate. So also the fact that a former judge exercised administrative responsibility in a court does not prevent the former judge from acting as a lawyer in a matter where the judge had previously exercised remote or incidental administrative responsibility that did not affect the merits. Compare the Comment to Rule 1.11. The term "adjudicative officer" includes such officials as judges pro tempore, referees, special masters, hearing officers and other judicial officers, and also lawyers who serve as part-time judges. Compliance Canons A(2), B(2) and C of the Model Code of Judicial Conduct provide that a part-time judge, judge pro tempore or retired judge recalled to active service, may not "act as a lawyer in any proceeding in which he served as a judge or in any other proceeding related thereto." Although phrased differently from this Rule, those Rules correspond in meaning.
 Like former judges, lawyers who have served as arbitrators, mediators or other third-party neutrals may be asked to represent a client in a matter in which the lawyer participated personally and substantially. This Rule forbids such representation unless all of the parties give their informed consent. See Rule 1.0(e). Other law or codes of ethics governing third-party neutrals may impose more stringent standards of personal or imputed disqualification. See Rule 2.4.
 Although lawyers who serve as third-party neutrals do not have information concerning the parties that is protected under Rule 1.6, they typically owe the parties an obligation of confidentiality under the law or codes of ethics governing third-party neutrals. Thus, paragraph (c) provides that conflicts of the personally disqualified lawyer will be imputed to other lawyers in a law firm unless the conditions of this paragraph are met.
 Requirements for screening procedures are stated in Rule 1.0(k). Paragraph (c)(1) does not prohibit the screened lawyer from receiving a salary or partnership share established by prior independent agreement, but that lawyer may not receive compensation directly related to the matter in which the lawyer is disqualified.
 Notice, including a description of the screened lawyer’s prior representation and of the screening procedures employed, generally should be given as soon as practicable after the need for screening becomes apparent. Notice must be given to the parties as well as to the appropriate tribunal.
