law: Sale of Goods Act, 1930
  13. When condition to be treated as warranty
  (1) Where a contract of sale is subject to any condition to be
  
  fulfilled by the seller, the buyer may waive the condition or elect to treat
  
  the breach of the condition as a breach of warranty and not as a ground for
  
  treating the contract as repudiated.
  (2) Where a contract of sale is not severable and the buyer has
  
  accepted the goods or part thereof, 5[***] the breach of any
  
  condition to be fulfilled by the seller can only be treated as a breach of
  
  warranty and not as a ground for rejecting the goods and treating the contract
  
  as repudiated, unless there is a term of the contract, express or implied, to
  
  that effect.
  (3) Nothing in this section shall affect the case of any
  
  condition or warranty fulfillment of which is excused by law by reason of
  
  impossibility or otherwise.
