law: Sale of Goods Act, 1930
  38. Installment deliveries
  (1) Unless otherwise agreed, the buyer of goods is not bound to
  
  accept delivery thereof by installments.
  (2) Where there is a contract for the sale of goods to be
  
  delivered by stated installments which are to be separately paid for, and the
  
  seller makes no delivery or defective delivery in respect of one or more
  
  installments, or the buyer neglects or refuses to take delivery of or pay for
  
  one or more installments, it is a question in each case depending on the terms
  
  of the contract and the circumstances of the case, whether the breach of
  
  contract is a repudiation of the whole contract, or whether it is a severable
  
  breach giving rise to a claim for compensation, but not to a right to treat the
  
  whole contract as repudiated.
