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.
