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. In doing so, they remain subject to the governing authority of the jurisdiction in which they are licensed to practice. If their activity in another jurisdiction is substantial and continuous, it may constitute practice of law in that jurisdiction. See Rule 5.5. If the rules of professional conduct in the two jurisdictions differ, principles of conflict of laws may apply.
Similar problems can arise when a lawyer is licensed to practice in more than one jurisdiction.
Where the lawyer is licensed to practice law in two jurisdictions which impose conflicting obligations, applicable rules of choice of law may govern the situation. A lawyer may be potentially subject to more than one set of rules of professional conduct which impose different obligations. The lawyer may be licensed to practice in more than one jurisdiction with differing rules, or may be admitted to practice before a particular court or agency with rules that differ from those of the jurisdiction or jurisdictions in which the lawyer is licensed to practice. In the past, decisions have not developed clear or consistent guidance as to which rules apply in such circumstances. The intention is for the latter exception to be a narrow one.
