(b) Misconduct. Acts or omissions by an attorney, individually or in concert with any other person or persons, which violate the attorney's oath of office or the rules or code of professional conduct currently in effect in the District of Columbia shall constitute misconduct and shall be grounds for discipline, whether or not the act or omission occurred in the course of an attorney- client relationship. Any of the following shall also be grounds for discipline:
(1) Conviction of a crime (see section 10);
(2) Discipline imposed in another jurisdiction (see section 11);
(3) Failure to comply with any order of the Court or the Board issued pursuant to this rule; or
(4) Failure to respond to a written inquiry from the Court or the Board in the course of a disciplinary proceeding without asserting, in writing, the grounds for refusing to do so.
(c) Review of board orders and inquiries. If an attorney objects in writing to an order or written inquiry of the Board, the objection shall be noted, but review of the order or inquiry by the Court shall not be available (except as provided in section 18 (c) with respect to subpoenas) until all proceedings before the Board have been concluded. If the Board imposes or recommends the imposition of a disciplinary sanction, the attorney may then seek review of the previously challenged order or inquiry by filing an appropriate motion or pleading with the Court. If the order or inquiry is reversed, vacated, or set aside by the Court, a previous failure to comply with the order or to respond to the inquiry shall not be a ground for discipline. If the order or inquiry is modified by the Court, failure to comply with the order or to respond to the inquiry may be a ground for discipline only to the extent that the order or inquiry is not modified.
