Stoppage in Transit under Sections 50 to 52 of the Sale of Goods Act, 1930: The Essentials, the Duration of Transit, How the Right Is Exercised, and Its Difference from Lien

Stoppage in transit is the unpaid seller's second line of defence. Once he has handed the goods to a carrier, his lien is gone, and the goods are travelling towards a buyer who may never pay. If that buyer becomes insolvent while the goods are still in transit, Section 50 lets the seller intercept them and resume possession. The right is narrow: it exists only on insolvency, only during transit, and only until the buyer or his agent takes delivery. Section 51 therefore defines with some care when transit begins and, more importantly, when it ends.

1. The Right and Its Essentials: Section 50

Section 50, Sale of Goods Act, 1930

Subject to the provisions of this Act, when the buyer of goods becomes insolvent, the unpaid seller who has parted with the possession of the goods has the right of stopping them in transit, that is to say, he may resume possession of the goods as long as they are in the course of transit, and may retain them until payment or tender of the price.

The seller must be unpaid within Section 45.
The buyer must be insolvent, in the commercial sense of Section 2(7A). Mere refusal to pay is not enough; this is the crucial difference from the lien.
The seller must have parted with possession, otherwise he has a lien and needs nothing more.
The goods must still be in transit, in the hands of a carrier or bailee who is an independent middleman rather than the buyer's own servant.
The effect is to restore the seller to possession, and with it something equivalent to his lien; it does not rescind the sale.

2. The Duration of Transit: Section 51

Transit begins when the goods are delivered to a carrier or other bailee for transmission to the buyer, and continues until the buyer or his agent takes delivery from that carrier or bailee.
Early delivery ends it. If the buyer or his agent obtains the goods before they reach the appointed destination, transit is over.
Acknowledgment ends it. If, after arrival at the appointed destination, the carrier acknowledges to the buyer that he holds the goods on his behalf and continues to hold them as his bailee, transit ends, and it does not matter that the buyer has indicated a further destination.
Rejection does not end it. If the buyer rejects the goods and the carrier keeps them, transit continues, even if the seller has refused to take them back.
Wrongful refusal ends it. If the carrier wrongfully refuses to deliver to the buyer, transit is deemed at an end, and the seller cannot stop goods the buyer was entitled to receive.
A ship chartered by the buyer raises a question of fact: whether the master holds as a carrier, in which case transit continues, or as the buyer's agent, in which case it does not.
Part delivery: the remainder may still be stopped, unless the part delivery shows an agreement to give up possession of the whole.

📖 Bethell & Co. v. Clark & Co., (1888) 20 QBD 615 (CA)

Facts: Goods were sold to a buyer in England who instructed the sellers to send them to a vessel bound for Australia, where he had already arranged a sub-sale. The sellers delivered them to the ship. The buyer became insolvent while the goods were at sea, and the sellers gave notice of stoppage.

Held: The stoppage was valid. Transit continued until the goods reached their ultimate destination and were taken by the buyer or his agent there. The shipowner held them as a carrier, not as the buyer's agent, so the goods were still in transit.

Ratio: Transit lasts until delivery at the destination contemplated by the contract. A carrier carrying the goods onward is not the buyer's agent for taking delivery.

📖 Lyons & Co. v. Hoffnung, (1890) 15 App Cas 391 (PC)

Facts: Goods were shipped to a buyer overseas, who sub-sold part of them while they were at sea. On arrival they were landed and placed in the possession of an agent, and the buyer became insolvent. The seller stopped the goods, and the question was whether transit had ended and whether the sub-sale defeated the right.

Held: The Privy Council upheld the stoppage. The goods had not yet been delivered to the buyer or an agent holding them for him as owner, so transit continued. The sub-sale did not defeat the seller's right, since no document of title had been transferred to the sub-buyer in the manner required.

Ratio: Transit continues until the buyer or his agent takes delivery as such, and a sub-sale alone does not defeat the right of stoppage.

3. How Stoppage Is Effected: Section 52

By taking actual possession of the goods, or
By giving notice of his claim to the carrier or other bailee in whose possession they are. The notice may be given to the person in actual possession or to his principal, and if to the principal, in time for him to communicate it to his servant or agent.
On notice, the carrier must redeliver the goods to the seller or according to his directions.
The expenses of redelivery are borne by the seller.
The carrier who ignores a valid notice delivers at his peril and may be liable in conversion to the seller.

4. Lien, Stoppage and Withholding Delivery

	Lien, ss. 47 to 49	Stoppage in transit, ss. 50 to 52
Possession	The seller still has the goods	The seller has parted with possession
Buyer's insolvency	Not required, except under s. 47(1)(c)	Essential
When available	Before delivery to a carrier	After delivery to a carrier, while in transit
How exercised	Simply by retaining the goods	By taking possession or giving notice, s. 52
Effect	The goods are held until payment	The goods are recovered and then held as before

Both differ from the right of withholding delivery under Section 46(2), which belongs to a seller who is still the owner because property has not passed. That seller does not need a lien over another's goods; he keeps what is his, and the Act gives him a right co-extensive with lien and stoppage.

5. The Position Stated Shortly

Section 50: an unpaid seller who has parted with possession may stop goods in transit if the buyer becomes insolvent.
Insolvency is essential, which distinguishes stoppage from the lien.
Transit runs from delivery to a carrier until the buyer or his agent takes delivery.
It ends on early delivery, on the carrier's acknowledgment that he holds for the buyer, and on wrongful refusal to deliver; it continues where the buyer rejects the goods.
Bethell v. Clark: transit lasted to the ultimate destination.
Lyons v. Hoffnung: a sub-sale alone did not defeat the right.
Section 52: stoppage is effected by taking possession or giving notice, and the carrier must redeliver at the seller's expense.
