(a) DOT may disqualify, and deny temporarily or permanently the privilege of appearing or practicing before it in any way to, any person who is found by DOT after written notice of charges and hearing to have engaged in unethical or improper professional conduct. Any violation of this part shall be deemed to be such conduct.

(b) When appropriate in the public interest, DOT may deny any application or other request of a party in a proceeding subject to this part where DOT finds after hearing that such party has, in connection with any DOT proceeding, violated any of the provisions of this part or any of the provisions of Chapter 11 of Title 18 of the United States Code. DOT may also condition its further consideration of such party's application or other request or the effectiveness of any order granting such application or other request upon such party's first taking such action as DOT may deem necessary or appropriate to remedy the violation of this part or Chapter 11 of Title 18 of the United States Code to prevent or deter any repetition of such violation. DOT may in addition issue a cease and desist order against any repetition of such or similar misconduct.

(c) The actions authorized by this section may take place within the framework of the matter during or concerning which the violations occur or in a separate matter, as the DOT decisionmaker or the presiding administrative law judge may direct. A complaint alleging that a violation has occurred in the course of a matter shall be filed in the docket or appropriate public file of such matter unless such complaint is made after DOT's decision of the matter has become final, in which event such complaint may be filed pursuant to part 302, subpart D of the rules of practice. A violation in the course of a matter which may be attributable to or affect the fitness of a party will ordinarily either be disposed of within the framework of such matter or be considered within the context of any subsequent matter involving the interests of such party. Other violations will ordinarily be disposed of in a separate proceeding.

(d) In the case of any violation of the provisions of this part, the violator may be subject to civil penalties under the provisions of 49 U.S.C. 46301. The violator may also be subject to a proceeding brought under 49 U.S.C. 46101 before the Department, or sections 46106 through 46108 of the Statute before a U.S. District Court, as the case may be, to compel compliance with civil penalties which have been imposed.
