law: Payment of Bonus Act, 1965 
  36. Power of exemption 
  If the appropriate government, having regard to the financial
  
  position and other relevant circumstances of any establishment or class of
  
  establishments, is of opinion that it will not be in public interest to apply
  
  all or any of the provisions of this Act thereto, it may, by notification in
  
  the Official Gazette, exempt for such period as may be specified therein and
  
  subject to such conditions as it may think fit to impose, such establishment or
  
  class of establishments from all or any of the provisions of this Act.
  Comment  : Bonus is treated as deferred wage. When
  
  the Parliament in its wisdom has enacted such a beneficial piece of social
  
  legislation which already guarantees minimum statutory bonus to employees
  
  governed by it, if the ir employers are to be allowed
  
  to earn exemption from the sweep of such a beneficial legislation which would
  
  ipso facto adversely affect entire class of their employees, the conditions for
  
  exercise of such power of exemption have to be strictly and objectively
  
  fulfilled by the repository of such a drastic power. A statutory right already
  
  accrues to employees under the Act. If the establishment employing such workmen
  
  or employees is desirous of depriving the statutory right of minimum bonus to
  
  its employees it may move the appropriate Government for exemption under
  
  Section 36 of the Act. State of T.N., Appellant v. K. Sabanayagam ,
