Disciplinary Authority; Choice Of Law
(a) Disciplinary Authority. A lawyer admitted to practice in this jurisdiction is subject to the disciplinary authority of this jurisdiction, regardless of where the lawyer's conduct occurs. A lawyer may be subject to the disciplinary authority of both this jurisdiction and another jurisdiction where the lawyer is admitted for the same conduct.
(b) Choice of Law. In any exercise of the disciplinary authority of this jurisdiction, the rules of professional conduct to be applied shall be as follows:
(1) for conduct in connection with a proceeding in a court before which a lawyer has been admitted to practice (either generally or for purposes of that proceeding), the rules to be applied shall be the rules of the jurisdiction in which the court sits, unless the rules of the court provide otherwise; and
(2) for any other conduct,
(i) if the lawyer is licensed to practice only in this jurisdiction, the rules to be applied shall be the rules of this jurisdiction, and
(ii) if the lawyer is licensed to practice in this and another jurisdiction, the rules to be applied shall be the rules of the admitting jurisdiction in which the lawyer principally practices; provided, however, that if particular conduct clearly has its predominant effect in another jurisdiction in which the lawyer is licensed to practice, the rules of that jurisdiction shall be applied to that conduct.
