When we have evidence that a representative fails to meet our qualification requirements or has violated the rules governing dealings with us, we may begin proceedings to suspend or disqualify that individual from acting in a representational capacity before us. We may file charges seeking such sanctions when we have evidence that a representative:
(a) Does not meet the qualifying requirements described in § 404.1705;
(b) Has violated the affirmative duties or engaged in the prohibited actions set forth in § 404.1740;
(c) Has been convicted of a violation under section 206 of the Act;
(d) Has been, by reason of misconduct, disbarred or suspended from any bar or court to which he or she was previously admitted to practice (see § 404.1770(a));
(e) Has been, by reason of misconduct, disqualified from participating in or appearing before any Federal program or agency (see § 404.1770(a)); or
(f) Who, as a non-attorney, has been removed from practice or suspended by a professional licensing authority for reasons that reflect on the person's character, integrity, judgment, reliability, or fitness to serve as a fiduciary.
