Appeal under section 63(2): Controllers must receive appellate orders and file appeals in their own names promptly. The Controller may appeal Appellate Controller orders where not satisfied; because the inclusive definition of Controller includes Assistant Controllers, differing dates of service can complicate computation of the appeal limitation. The Board directs Appellate Controllers to communicate orders to the Controller, requires Assistant Controllers to notify Controllers immediately of any orders served on them, and mandates that appeals be filed by the Controller in the Controller's own name.
