J sold a machine to K. K gave a cheque for the payment. The cheque was dishonoured. But J handed over a delivery order to K. K sold the goods to R on the basis of the delivery order. J wanted to exercise his right of lien on the goods. Can he do so under the provisions of the Sale of Goods Act, 1930?

The right of lien and stoppage in transit are meant to protect the seller. These will not be affected even when the buyer has made a transaction of his own goods which were with the seller under lien. But under two exceptional cases these rights of the seller are affected:-\n(i) When the buyer has made the transaction with the consent of the seller\n(ii) When the buyer has made the transaction on the basis of documents of title such as bill of lading, railway receipt or a delivery order etc. \nIn the given case, J has sold the machine to K and K gave a cheque for the payment. But the cheque was dishonoured that means J, the seller is an unpaid seller. So, he is entitled to exercise the right of lien, but according to section 53(1) his right of lien is defeated because he has given the document of title to the buyer and the buyer has made a transaction of sale on the basis of this document. So, R who has purchased the machine from K can demand the delivery of the machine.
