  giving the parties to the dispute a reasonable opportunity of being heard,
  
  determine the amount of gratuity payable to an employee, and, if as a result of

  satisfied that there is no dispute as to the right of the applicant to receive
  
  the amount of gratuity.
  (5) For the purpose of conducting an inquiry under sub-section
  
  (4), the controlling authority shall have the same powers as are vested in a

  within sixty days from the date of the receipt of the order, prefer an appeal
  
  to the appropriate Government or such other authority as may be specified by
  
  the appropriate Government in this behalf :
  Provided that the appropriate Government or the
  
  appellate authority, as the case may be, may, if it is satisfied that the
  
  appellant was prevented by sufficient cause from preferring the appeal within
  
  the said period of sixty days, extend the said period by a further period of
  
  sixty days.
  (8) The appropriate Government or the appellate authority, as
  
  the case may be, may, after giving the parties to the appeal a reasonable opportunity
  
  of being heard, confirm, modify or reverse the decision of the controlling
  
  authority.
