law: Companies Act, 1956
  Sec 145    -    
  
  Application of Part to charges requiring registration under it but not under
  
  previous law. 
  In respect of any charge created before, and remaining
  
  unsatisfied at, the commencement of this Act, which, if this Act had been in
  
  force at the relevant time, would have had to be registered by the company in
  
  pursuance of this Part but which did not require registration under the Indian
  
  Companies Act, 1913 (7 of 1913), and in respect of all matters relating to such
  
  charge, the provisions of this Part shall apply and have effect in all
  
  respects, as if the date of commencement of this Act had been substituted
  
  therein for the date of creation of the charge, or the date of completion of
  
  the acquisition of the property subject to the charge as the case may be.
  
  Nothing contained in this section shall be deemed to affect the relative
  
  priorities as they existed immediately before the commencement of this Act, as
  
  between charges on the same property.
