If the Board determines that the crime of which respondent was convicted is not one involving moral turpitude per se, the matter shall be referred to a hearing committee to determine if the conduct underlying respondent’s offense involves moral turpitude within the meaning of D.C. Code Section 11-2503(a). Bar Counsel may file a petition instituting a proceeding pursuant to Section 8 of Rule XI based on the conduct underlying respondent’s crime. If Bar Counsel files a petition, it shall be filed within fifteen (15) days of the Board’s order referring the matter to a hearing committee. The Executive Attorney shall consolidate the matters before the hearing committee. Whether or not the Hearing Committee concludes that the offense involves moral turpitude, the Hearing Committee shall determine if respondent’s conduct violated the disciplinary rules charged in the petition, if Bar Counsel filed a petition and, if so, shall recommend an appropriate sanction so that the Board may have the benefit of the Hearing Committee’s views on violation and sanction in the event that the Board finds no moral turpitude is involved.
