  46. Unpaid seller's rights
  (1) Subject to the provisions of this Act and of any law for the
  
  time being in force, notwithstanding that the property in the goods may have
  
  passed to the buyer, the unpaid seller of goods, as such, has by implication of
  
  law-
  (a) a lien on the goods for the price while he
  
  is in possession of them;
  (b) in case of the insolvency of the buyer a
  
  right of stopping the goods in transit after he has parted with the possession
  
  of them;
  (c) a right of re-sale as limited by this Act.
  
  
  (2) Where the property in goods has not passed to the buyer, the
  
  unpaid seller has, in addition to his other remedies, a right of withholding
  
  delivery similar to and co-extensive with his rights of lien and stoppage in
  
  transit where the property has passed to the buyer.
