17 C.F.R. §§ 14.4–14.7

The Commission may deny, temporarily or permanently, the privilege of appearing or practicing before it in any way to any person who is found by the Commission, after notice of and opportunity for hearing in the matter, to have violated, caused, or aided and abetted any violation of the Commodity Exchange Act, as amended, 7 U.S.C. 1 et seq., or the rules and regulations adopted thereunder.

Any person who after licensing or certification to practice his profession by any competent authority has been convicted of any felony or of a misdemeanor involving fraud or involving moral turpitude in matters related to the regulatory responsibilities of the Commission, and whose conviction has not been reversed by an appellate court, may not appear or practice before the Commission. A conviction within the meaning of this section shall be deemed to have occurred when the convicting court enters its judgment or order, regardless of whether an appeal is pending or could be taken, and includes a judgment on a plea of nolo contendere.

Any attorney who has been suspended or disbarred by a Court of the United States or any state or territory or the District of Columbia and any person whose license to practice as an accountant has been revoked or suspended in any state or territory or the District of Columbia may not appear or practice before the Commission during the period when such suspension or revocation is in effect. A suspension or revocation shall be deemed to have occurred when the disbarring, suspending or revoking agency or tribunal enters its order, regardless of whether appeal is pending or could be taken, and includes a judgment or order on a plea of nolo contendere or the procedural equivalent of such a plea. For purposes of this section it shall be irrelevant that any attorney or accountant who has been suspended, disbarred, or otherwise disqualified from practice before a court or in a jurisdiction continues in professional good standing before other courts or in other jurisdictions.
