134.215—Interlocutory appeals.
        
        (a) General.
         A motion for leave to take an interlocutory appeal from a Judge's ruling will not be entertained in those proceedings in which OHA issues final decisions. In all other cases, an interlocutory appeal will be permitted only if, upon motion by a party, or upon the Judge's own initiative, the Judge certifies that his or her ruling raises a question which is immediately appealable. Interlocutory appeals will be decided by the AA/OHA or a designee.
    
    
        
        (b) Motion for certification.
         A party must file and serve a motion for certification no later than 20 days after  issuance of the ruling to which the motion applies. A denial of the motion does not preclude objections to the ruling in any subsequent request for review of an initial decision.
    
    
        
        (c) Basis for certification.
         The Judge will certify a ruling for interlocutory appeal only if he or she determines that:
    
    
        
        (1) 
         The ruling involves an important question of law or policy about which there is substantial ground for a difference of opinion; and
    
    
        
        (2) 
         An interlocutory appeal will materially expedite resolution of the case, or denial of an interlocutory appeal would cause undue hardship to a party.
    
    
        
        (d) Stay of proceedings.
         A stay while an interlocutory appeal is pending will be at the discretion of the Judge.
