If a party or the party's representative fails or refuses to comply with a Board order or rule, or engages in unreasonable or vexatious conduct, the Board may, on its own initiative or on motion of a party, sanction the offending party or representative as it considers necessary to the just and expeditious conduct of the case.
The Board may deny any party's representative from appearing in a case currently before it if that individual is found by the Board, after hearing, either to be lacking in the requisite qualifications to represent others or to have engaged in unethical, improper or unprofessional conduct.
