  90. Revision.  
  The State  Transport 
  
  Appellate Tribunal may, on an application made  to it,  call for  the record of 
  
  any case in which an order has  been made  by  a  State  Transport  Authority  
  
  or  Regional Transport Authority against which no appeal lies, and if it appears 
  
  to the State  Transport Appellate  Tribunal that  the order  made by  the State 
  
  Transport  Authority or Regional Transport Authority is improper or illegal, the 
  
  State Transport Appellate Tribunal may pass such order in relation  to the case 
  
  as it deems fit and every such order shall be final:
  Provided that the State 
  
  Transport Appellate Tribunal shall not entertain any application from a person 
  
  aggrieved by an order of a State Transport Authority or Regional Transport 
  
  Authority, unless the application is made within thirty days from the date of 
  
  the order:
  Provided further  that the 
  
  State Transport Appellate Tribunal may entertain the  application after  the 
  
  expiry  of the  said  period  of thirty days,  if it  is satisfied  that the 
  
  applicant was prevented by good and sufficient cause from making the application 
  
  in time: Provided also  that the  State Transport Appellate Tribunal shall not 
  
  pass an order under this section prejudicial to any person without giving him a 
  
  reasonable opportunity of being heard.
