D.C. R. Prof'l. Cond. 1.12
COMMENT
[1] 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 informed consent. For the definition of "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.
[2] 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 this paragraph are met.
[3] Requirements for screening procedures are stated in Rule 1.0(l). 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. See D.C. Bar Legal Ethics Committee Opinion 279.
[4] 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.
[5] With respect to statements filed with Disciplinary Counsel pursuant to paragraph (d), see Comments [8] and [9] to Rule 1.11.
