law: Contact Labour (Regulation and Abolition) Act, 1970
  30. Effect of laws and agreements inconsistent with this
  
  Act
  (1) The provisions of this Act shall have effect notwithstanding
  
  anything inconsistent therewith contained in any other law or in the terms of
  
  any agreement or contract of service, or in any standing orders applicable to
  
  the establishment whether made before or after the commencement of the Act:
  PROVIDED that where under any such agreement, contract
  
  of service or standing orders the contract labor employed, in the establishment
  
  are entitled to benefits in respect of any matter which are more favorable to
  
  them than those to which they would be entitled under this Act, the contract
  
  labor shall continue to be entitled to the more favorable benefits in respect
  
  of that matter, notwithstanding that they received benefits in respect of other
  
  matters under this Act.
  (2) Nothing contained in this Act shall be construed as
  
  precluding any such contract labor from entering into an agreement with the
  
  principal employer or the contractor, as the case may be, for granting them
  
  rights or privileges in respect of any matter which are more favorable to them
  
  than those to which they would be entitled under this Act.
