  of the first category to be presumed to  be correct throughout the territory of
  
  India. -
  (1)Every
  
  weight or measure of the first category which is stamped with the special seal
  
  referred to in sub-section (3) of Sec. 41 shall be presumed to be correct
  
  throughout the territory of India and shall not be required, until its
  
  re-verification in the transferee State becomes due to efflux of time, to be
  
  verified or stamped in the transferee State:
  Provided that where the local
  
  Inspector in the transferee State has any reason to believe that any weight or
  
  measure of the first category has lost its accuracy in transit or has, for any
  
  other reason, ceased to conform to the standards of weight or measure
  
  established by or under this Act, he may, for reasons to be recorded by him in
  
  writing, and communicated to the Controller of the transferor State, through
  
  the Controller of the transferee State, -
  (a) Verify such weight
  
  or measure: and
  (b) If, on
  
  verification such weight or measure is found to be inaccurate, -
  (i)
  
  Cause such adjustment as is necessary to be made so as to make it conform to t
  
  lie standards established by or under this Act, or
  (ii)
  
  Where he is of opinion that such adjustment is not possible, reject it and
  
  obliterate the stamp thereon:
  Provided further that where any 
  
  verification, adjustment or obliteration is made in exercise of the powers 
  
  conferred by the foregoing proviso, no fee shall be charged for such 
  
  verification, adjustment or obliteration.
  (2) In computing the
  
  time when the re-verification of a weight or measure of the first category
  
  shall become due in the transferee State, the period during which such weight
  
  or measure remains unsold or undistributed in the transferee State, shall be
  
  excluded.
