(a) Except as stated in paragraph (c) of this section, a covered USG attorney shall not represent anyone in connection with a matter in which the covered USG attorney 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 give informed consent, confirmed in writing.

(b) A covered USG attorney 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 covered USG attorney is participating personally and substantially as a judge or other adjudicative officer. A covered USG attorney serving as 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 covered USG attorney has notified the judge, other adjudicative officer, or arbitrator, and been disqualified from further involvement in the matter.

(c) An arbitrator selected as a partisan of a party in a multi-member arbitration panel is not prohibited from subsequently representing that party.

(d) [Reserved]
