Civil Code, Art. 1599

Where there is a breach of warranty by the seller, the buyer may, at his election: (1) Accept or keep the goods and set up against the seller, the breach of warranty by way of recoupment in diminution or extinction of the price; (2) Accept or keep the goods and maintain an action against the seller for damages for the breach of warranty; (3) Refuse to accept the goods, and maintain an action against the seller for damages for the breach of warranty; (4) Rescind the contract of sale and refuse to receive the goods or if the goods have already been received, return them or offer to return them to the seller and recover the price or any part thereof which has been paid. When the buyer has claimed and been granted a remedy in anyone of these ways, no other remedy can thereafter be granted, without prejudice to the provisions of the second paragraph of article 1191. Where the goods have been delivered to the buyer, he cannot rescind the sale if he knew of the breach of warranty when he accepted the goods without protest, or if he fails to notify the seller within a reasonable time of the election to rescind, or if he fails to return or to offer to return the goods to the seller in substantially as good condition as they were in at the time the ownership was transferred to the buyer. But if deterioration or injury of the goods is due to the breach or warranty, such deterioration or injury shall not prevent the buyer from returning or offering to return the goods to the seller and rescinding the sale. Where the buyer is entitled to rescind the sale and elects to do so, he shall cease to be liable for the price upon returning or offering to return the goods. If the price or any part thereof has already been paid, the seller shall be liable to repay so much thereof as has been paid, concurrently with the return of the goods, or immediately after an offer to return the goods in exchange for repayment of the price. Where the buyer is entitled to rescind the sale and elects to do so, if the seller refuses to accept an offer of the buyer to return the goods, the buyer shall thereafter be deemed to hold the goods as bailee for the seller, but subject to a lien to secure the payment of any portion of the price which has been paid, and with the remedies for the enforcement of such lien allowed to an unpaid seller by article 1526. (5) In the case of breach of warranty of quality, such loss, in the absence of special circumstances showing proximate damage of a greater amount, is the difference between the value of the goods at the time of delivery to the buyer and the value they would have had if they had answered to the warranty.
