Distinguish between seller's right of lien and stoppage of goods in Transit

The Seller's Lien — Section 47

Section 47(1) entitles the unpaid seller who is in actual possession of the goods to retain that possession until payment or tender of the price, in three specified situations: where the goods were sold without any stipulation as to credit; where sold on credit but the credit period has since expired; and where the buyer has become insolvent. This right is purely possessory, depending on the seller's continuing physical control of the goods rather than on his ownership of them, and it survives even where he holds the goods merely as agent or bailee rather than in his original capacity as seller.

The illustration of sugar sold on three months' credit, remaining throughout in the seller's own warehouse, shows the lien reviving automatically once the credit period lapses without payment, entirely independent of any insolvency. Where insolvency occurs even before the credit period expires, the seller may retain the goods immediately, since an insolvent buyer could not demand delivery in any event. The lien secures only the price itself, not incidental expenses such as storage charges, and it is extinguished by a valid tender of the price even if wrongfully refused. It is equally extinguished automatically once the seller parts with possession, as in an FOB contract, where the lien ends the instant goods are placed on board the vessel.

The Right of Stoppage in Transit — Section 50

Section 50 provides that where the buyer becomes insolvent, the unpaid seller who has already parted with possession of the goods may resume possession of them while they remain in the course of transit, retaining them until payment or tender of the price. This right rests on the equitable principle that one man's property should not be applied to satisfy another man's debts. Four conditions must all coexist: the seller must be unpaid; the buyer must be insolvent; the seller must have already parted with possession; and the buyer must not yet have obtained actual possession. Section 51 defines the transit period as beginning upon delivery to a carrier and ending upon the buyer's actual receipt, subject to earlier termination through premature delivery or the carrier's attornment to the buyer. Section 52 permits exercise of this right either by actual repossession or by timely notice to the carrier, who must then re-deliver the goods according to the seller's directions at the seller's expense.

Points of Distinction

Why the Two Rights Are Complementary, Not Overlapping

The lien and stoppage in transit never operate simultaneously over the same goods — the moment the seller delivers goods to a carrier for transmission without reserving a right of disposal, his lien is extinguished under Section 49, and it is at exactly this point that the possibility of stoppage in transit arises, provided the buyer subsequently becomes insolvent while the goods are still in the carrier's hands. In this sense, the two remedies form a continuous chain of protection for the unpaid seller — the lien covers him while the goods remain under his own roof, and stoppage in transit extends that protection into the interval after dispatch but before actual delivery to the buyer, closing what would otherwise be a dangerous gap in his ability to secure payment.

Illustration Distinguishing the Two Rights

A seller who sells specific goods on credit and retains them in his own warehouse throughout the credit period exercises his lien if the buyer fails to pay once that period expires. If, instead, the seller had already sent the goods off by rail before the credit period expired, and the buyer became insolvent while the goods were still with the railway carrier, the seller could no longer rely on his lien, since he no longer possesses the goods — but he could instead invoke his right of stoppage in transit, giving notice to the railway administration to withhold delivery from the insolvent buyer. This side-by-side comparison shows precisely why the Act treats these as two distinct, though closely related, remedies rather than a single undifferentiated right.

Common Features Shared by Both Rights

Despite their differences, both rights share certain features. Neither right, by itself, rescinds the underlying contract of sale — this is expressly confirmed for stoppage under Section 54(1), and the same principle applies equally to the lien. Both rights operate purely against the goods themselves, giving the seller no personal claim beyond what the goods can satisfy. Both are also defeated, in similar fashion, where the buyer has transferred a document of title to an innocent sub-purchaser or pledgee for value under Section 53, subject to the qualification that a sub-sale defeats the seller's rights entirely, while a sub-pledge only subordinates them to the pledgee's interest.
