RULE 1.12 FORMER JUDGE, ARBITRATOR, MEDIATOR, ADJUDICATIVE OFFICER, THIRD-PARTY NEUTRAL, AND LAW CLERKS
(a) Except as stated in paragraph (d), a lawyer shall not represent anyone in connection with a matter in which the lawyer participated personally and substantially as a judge or other adjudicative officer
, arbitrator or law clerk to such a person, or as an arbitrator, mediator, or other third-party neutral, unless all parties to the proceeding consent in writing after consultation.
(b) A lawyer shall not negotiate for employment with any person who is involved as a party or as attorney for a party in a matter in which the lawyer is participating personally and substantially as a judge or other adjudicative officer
, or arbitrator, mediator, or other third-party neutral. A lawyer serving as a law clerk to a judge , or other adjudicative officer or, arbitrator, mediator, or other third-party neutral may negotiate for employment with a party or attorney involved in a matter in which the clerk is participating personally and substantially, but only after the lawyer has notified the judge , or other adjudicative officer or, arbitrator, mediator, or other third-party neutral.
(c) If a lawyer is disqualified by paragraph (a), no lawyer in a firm with which that lawyer is associated may knowingly undertake or continue representation in the matter unless:
The the disqualified lawyer is timely screened from any participation in the matter and is apportioned no part of the fee therefrom; and
Written written notice is promptly given to the parties and any appropriate tribunal to enable them to ascertain compliance with the provisions of this rule.
(d) An arbitrator selected as a partisan of a party in a multi-member arbitration panel is not prohibited from subsequently representing that party.
 This Rule generally parallels Rule 1.11. The term "personally and substantially" signifies that a judge who was a member of a multimember 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. The term "adjudicative officer" includes such officials as judges pro tempore, referees, special masters, hearing officers and other parajudicial officers
, mediators, fact finders, conciliators, and also lawyers who serve as part-time judges. The compliance section of the Rules of Judicial Conduct Paragraphs (A)(2), (B)(2) and (C) of the Compliance section of the North Dakota 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 a proceeding in which the person has served as a judge or in any other proceeding related thereto." This rule is consistent with the Rules of Judicial Conduct.
 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 to the proceedings give their consent in writing. See Rule 1.0(b). Other law or codes of ethics governing third-party neutrals may impose more stringent standards of personal or imputed disqualification. See Rule 2.3.
 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 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 that paragraph are met.
 Requirements for screening procedures are stated in Rule 1.0(n). 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, should be given as soon as practicable after the need for screening becomes apparent.
