416.1545—Violations of our requirements, rules, or standards.
         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:
    
    
    
        
        (b) 
         Has violated the affirmative duties or engaged in the prohibited actions set forth in  § 416.1540 ;
    
    
    
        
        (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  § 416.1570(a) ); or
    
    
        
        (e) 
         Has been, by reason of misconduct, disqualified from participating in or appearing before any Federal program or agency (see  § 416.1570(a) ).
