(a) Representation. In any proceeding before the Board, an Appellant may appear in person or by appointing a duly authorized individual as his or her Representative.

(b) Appearance. No individual may appear as a Representative in a proceeding before the Board without first filing with the Clerk a written authorization signed by the Appellant to be represented. When accepted by the Board, such Representative will continue to be recognized unless the Representative withdraws or abandons such capacity or the Appellant directs otherwise.

(c) Change of address. Each Appellant and Representative authorized to appear before the Board must give the Clerk written notice of any change to the address or telephone number of the Appellant or Representative. Such notice must identify the docket number and name of each pending appeal for that Appellant, or, in the case of a Representative, in which he or she is a Representative before the Board. Absent such notice, the mailing of documents to the address most recently provided to the Board will be fully effective.

(d) Debarment of Counsel or Representative. In any proceeding, whenever the Board finds that a person acting as counsel or other Representative for the Appellant or the Director, is guilty of unethical or unprofessional conduct, the Board may order that such person be excluded from further acting as counsel or Representative in such proceeding. Such order may be appealed to the Secretary of Labor or his or her designee, but proceedings before the Board will not be delayed or suspended pending disposition of such appeal. However, the Board may suspend the proceeding of an appeal for a reasonable time for the purpose of enabling Appellant or the Director to obtain different counsel or other Representative. Whenever the Board has issued an order precluding a person from further acting as counsel or Representative in a proceeding, the Board will, within a reasonable time, submit to the Secretary of Labor or his or her designee a report of the facts and circumstances surrounding the issuance of such order. The Board will recommend what action the Secretary of Labor should take in regard to the appearance of such person as counsel or Representative in other proceedings before the Board. Before any action is taken debarring a person as counsel or Representative from other proceedings, he or she will be furnished notice and the opportunity to be heard on the matter.

(e) Fees for attorney, Representative, or other services. No claim for a fee for legal or other service performed on appeal before the Board is valid unless approved by the Board. Under 18 U.S.C. 292, collecting a fee without the approval of the Board may constitute a misdemeanor, subject to fine or imprisonment for up to a year or both. No contract for a stipulated fee or on a contingent fee basis will be approved by the Board. No fee for service will be approved except upon written application to the Clerk, supported by a statement of the extent and nature of the necessary work performed before the Board on behalf of the Appellant. The fee application will be served by the Clerk on the Appellant and a time set in which a response may be filed. Except where such fee is de minimis, the fee request will be evaluated with consideration of the following factors:
