(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, mediator, or law clerk to such a person, unless all parties to the proceeding consent after consultation.

(b) A lawyer shall not negotiate for employment with any person who is involved as a party or as lawyer for a party in a matter in which the lawyer is participating personally and substantially as a judge or other adjudicative officer, arbitrator, or mediator. A lawyer serving as a law clerk to a judge, other adjudicative officer, arbitrator or mediator may negotiate for employment with a party or lawyer involved in a matter in which the clerk is participating personally and substantially, but only after the lawyer has notified the judge, other adjudicative officer, arbitrator, or mediator.

(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:

(1) the disqualified lawyer is screened from any participation in the matter and is apportioned no part of the fee therefrom; and

(2) written notice is promptly given to the appropriate tribunal to enable it to ascertain compliance with the provisions of this rule.

(d) An arbitrator selected as a partisan of a party in a multimember arbitration panel is not prohibited from subsequently representing that party.

Adopted June 9, 1997, effective January 1, 1998.


[1] 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 by these Rules 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 lawyer should also consider applicable statutes and regulations, e.g. G. L. c. 268A . The term "adjudicative officer" includes such officials as magistrates, referees, special masters, hearing officers and other parajudicial officers. Canon 8A(2) of the Code of Judicial Conduct (S.J.C. Rule 3:09) provides that a retired judge recalled to active service "should not enter an appearance nor accept an appointment to represent any party in any court of the Commonwealth for a period of six months following the date of retirement, resignation or most recent service as a retired judge pursuant to G. L. c. 32, §§ 65E-65G ."

[2] Law clerks who serve before they are admitted to the bar are subject to the limitations stated in Rule 1.12(b).
