Final answer:
An unpaid seller can exercise the right to possessory lien even after making partial delivery of the goods.
Step-by-step explanation:
Yes, an unpaid seller may still exercise the right to possessory lien even if they have made partial delivery of the goods. The right to possessory lien allows the seller to retain possession of the goods until payment is made by the buyer. This means that the seller can withhold the remaining goods until the buyer fulfills their payment obligations. The seller's right to possessory lien is not affected by the partial delivery of goods.
