Buyer's Claim for Non-Conforming Goods Rejected on Evidentiary and Waiver Grounds

The dispute arose from a contract for the sale of goods where the buyer claimed non-conformity due to a defect in the material, which was discovered after delivery and payment, leading to a refusal to pay the remaining balance. The court of appeal upheld the lower court's decision, which had ruled against the buyer, finding that the buyer had failed to provide sufficient evidence demonstrating that the defect existed at the time of delivery and that the buyer had waived their right to complain by not acting promptly upon discovery. The highest court affirmed this decision, reasoning that the mere existence of a defect after delivery does not automatically imply that the goods were non-conforming at the time of transfer, and the findings regarding the buyer's conduct and lack of timely notification were matters of factual assessment that were sufficiently supported by the evidence presented below.
