Rule 1.12 Former Judge or Arbitrator

(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, 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 an 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. A lawyer serving as a law clerk to a judge, other adjudicative officer, or arbitrator 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, other adjudicative officer, or arbitrator.

(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.
