When is the condition reduced to the status of warranty?

The Statutory Text

Section 13 identifies three distinct situations in which a buyer, though otherwise entitled to treat a stipulation as a condition and reject the goods, is instead confined to treating the breach as a breach of warranty. The provision recognises that the right to reject, though valuable, is not absolute — it can be lost through the buyer's own conduct or through the peculiar structure of the contract itself.

First Ground: Voluntary Waiver by the Buyer

Section 13(1) provides that where a contract of sale is subject to any condition to be fulfilled by the seller, the buyer may waive the condition. Once he has done so, he cannot afterwards insist on its fulfilment or treat its breach as entitling him to reject the goods. Waiver here means a deliberate, voluntary relinquishment of a known right — the buyer, being aware that a condition has been broken, nonetheless elects, expressly or by clear implication, to proceed with the contract as though the condition did not matter. Having made that election, the law will not permit him to reverse it later merely because it becomes convenient to do so.

Second Ground: Election to Treat Breach of Condition as Breach of Warranty

Section 13(1) further provides that the buyer may elect to treat the breach of any such condition as a breach of warranty, and not as grounds for treating the contract as repudiated. This differs subtly from outright waiver — here, the buyer does not overlook the breach altogether, but instead accepts the goods while reserving his claim for compensation, treating the defect as though it were merely a warranty violation rather than a condition failure. This flexible right of election was applied by the Supreme Court in Svenska Handelsbanken v. Indian Charge Chrome, where the contract had stipulated, as a condition, the establishment of a power plant of a specified 108 MW capacity. Though this condition was breached, the plaintiff continued operating the plant rather than repudiating the contract, and the Court held that by this conduct the plaintiff had elected under Section 13 to treat the breach as one of warranty only — confining its remedy to damages, with no right to reject or terminate.

Third Ground: Acceptance of Goods Under an Indivisible Contract

The most far-reaching of the three grounds is found in Section 13(2), which provides that where a contract of sale is not severable, and the buyer has accepted the goods, or part thereof, the breach of any condition to be fulfilled by the seller can only be treated as a breach of warranty, and not as a ground for rejecting the goods and treating the contract as repudiated — unless the contract contains a term, express or implied, to that effect. In other words, once a buyer has accepted goods under a single, indivisible contract, he permanently loses the right to reject them for breach of condition, however serious that breach may have been in substance, and his remedy shrinks to a claim for damages alone.

This provision must be read together with Section 42, which tells us precisely what conduct amounts to "acceptance" for this purpose. A buyer is deemed to have accepted the goods when he intimates to the seller that he has accepted them; or when, having received the goods, he does any act in relation to them that is inconsistent with the ownership of the seller — such as reselling them or using them without proper inspection; or when he retains the goods beyond a reasonable time without intimating to the seller that he has rejected them. It is worth noting, however, that under Section 41 a buyer is entitled to a reasonable opportunity to examine the goods before he is deemed to have accepted them, so mere receipt of the goods, without such an opportunity, does not by itself amount to acceptance.

The Supreme Court's approach in C.N. Anantharam v. Fiat India Ltd. illustrates how this framework operates in a modern consumer dispute. There, a buyer complained of a manufacturing defect in a car and sought its outright replacement, treating the defect as amounting to breach of a fundamental condition. The Court examined whether the defect was of such a nature as to justify rejection, or whether it was a curable defect that the buyer had, in substance, accepted by continuing to use the vehicle — in which case the appropriate remedy would lie in damages for breach of warranty, once the defective part was repaired, rather than outright rejection of the goods. This case shows the practical operation of Section 13(2): prolonged use and retention of goods after knowledge of the defect tends strongly to reduce what might otherwise be a condition to the level of a warranty, since such conduct is itself treated as acceptance.

Why the Contract Being "Severable" Matters

The qualification in Section 13(2) — that this reduction applies only where the contract "is not severable" — deserves emphasis. Where a contract is severable, meaning it can be divided into separate parts corresponding to separate consideration (as under Section 38, which deals with instalment deliveries), acceptance of one instalment does not necessarily bar the buyer from rejecting a later, defective instalment as a breach of condition. It is only in an indivisible, single contract that acceptance of the goods as a whole locks the buyer into treating any condition-breach as a mere warranty-breach going forward.

Bringing the Three Grounds Together

Taken together, these three grounds reflect a single underlying policy — the law does not wish to leave a seller perpetually exposed to rejection long after the buyer has, through his own conduct, treated the transaction as concluded. Once a buyer has knowingly waived a defect, elected to proceed despite it, or accepted the goods under an indivisible bargain, fairness to the seller demands that the buyer's remedy be confined to compensation rather than the more drastic remedy of rescission that a true, unspent breach of condition would otherwise have afforded him.
