On application duly made, an administrative law judge may reopen a case where a decision was rendered upon or following the default of a party affected thereby or following the withdrawal of a request for hearing by a party. Such application shall be made to the chief administrative law judge or a senior administrative law judge who thereupon shall designate an administrative law judge to act upon the application. If such party shows good cause for his default or for his withdrawal of his request for a hearing, he shall be entitled to a hearing on the merits and the case shall be heard at the same time the application is acted upon.
