(a) Suspension or change of rules. These rules may, from time to time, be suspended, amended or revoked in whole or in part. Notice of such action will be published in the Federal Register.

(b) Commission waiver of procedures. In the interest of expediting decision or to prevent undue hardship on any party or for other good cause the Commission may order the adoption of expedited procedures, may waive any rule in this part in a particular case, and may order proceedings in accordance with its direction upon a determination that no party will be prejudiced thereby, and that the ends of justice will be served. Reasonable notice shall be given to all parties of any action taken pursuant to this provision.
