Nutrimix Feeds Corporation vs. Spouses Evangelista

A seller cannot be held liable for breach of warranty against hidden defects absent proof that the defect existed at the time the product left the seller's control, especially where there is a substantial delay in testing and a break in the chain of custody of the product.

Spouses Efren and Maura Evangelista procured animal feeds on credit from Nutrimix Feeds Corporation starting April 5, 1993. After the massive death of their broilers and hogs in late July 1993, the respondents ceased payment on their outstanding account of ₱766,151.00, which comprised both unissued checks and dishonored checks drawn on a closed bank account. The respondents attributed the animal deaths to contaminated feeds supplied by the petitioner.

• Credit Purchases: Respondents purchased animal feeds from petitioner on a 30- to 45-day credit term, issuing postdated checks. The respondents accumulated an unpaid balance of ₱766,151.00, representing deliveries not covered by checks and checks dishonored due to a closed account.
• Animal Mortality: On July 26 and 27, 1993, feeds were delivered and fed to the respondents' broilers and hogs. By the evening of July 26 and throughout July 27, approximately 18,000 broilers and the hogs died.
• Delayed Testing: The surviving feeds were not submitted for laboratory examination until October 20, 1993, nearly three months after the animal deaths.
• Laboratory Findings: Tests conducted by various government agencies yielded conflicting or inconclusive results. The Bureau of Animal Industry found high aflatoxin levels but noted it would not cause instantaneous death. The Philippine Nuclear Research Institute found that feeds given to healthy chickens caused death, but the scientist admitted the feeds were in an unmarked plastic bag and could not confirm they were manufactured by the petitioner. The NBI detected rat poison (Coumatetralyl), and the Bureau of Plant Industry detected Warfarin.
• Chain of Custody Flaws: The feeds submitted for testing were taken from a sealed bag, not from the specific batches fed to the animals. No examination of the dead animals' stomachs was conducted to determine the actual cause of death.
• Feeding Practices: Respondent Maura Evangelista admitted to mixing different types of animal feeds, such as chicken booster mash with hog feed, without veterinary advice.
• Shifting Justifications: During a meeting with the petitioner's president in early August 1993, the respondents claimed their animals were suffering from a disease and requested continued credit. They only later claimed that the feeds were contaminated with poison.

• Insufficiency of Evidence: Petitioner argued that the testimony of Dr. Rodrigo Diaz regarding the sealed sack of Nutrimix feeds is not conclusive evidence of hidden defects attributable to the petitioner.
• Lack of Identity of Feeds: Petitioner contended that even assuming the tested feeds came from a sealed sack bearing the Nutrimix brand, it cannot be presumed that these were the exact same feeds delivered to the respondents' farm and consumed by the animals.

• Breach of Warranty: Respondents countered that the Court of Appeals correctly dismissed the collection complaint because the petitioner was guilty of breach of warranty against hidden defects.
• Sufficiency of Evidence: Respondents maintained that there was sufficient basis to hold the petitioner liable, releasing them from the obligation to pay their outstanding debt.

• Breach of Warranty: Whether there is sufficient evidence to hold the petitioner guilty of breach of warranty due to hidden defects in the animal feeds sold.

• Breach of Warranty: The petitioner was not guilty of breach of warranty due to hidden defects. To establish liability for breach of implied warranty, the buyer must prove that the defect existed when the product left the seller's control. The three-month delay between the animal deaths and the laboratory examination enfeebles the claim, as the feeds could have been contaminated by outside factors beyond the seller's control. Furthermore, there was no evidence establishing that the feeds submitted for testing were the same ones delivered and consumed. The tested feeds came from a sealed bag, and the dead animals were never subjected to necropsy or stomach analysis to determine the actual cause of death. The respondents' practice of mixing different feeds and their initial attribution of the animal deaths to disease further undermine the claim of hidden defects attributable to the seller.

• Warranty Against Hidden Defects — The vendor is responsible for hidden defects that render the thing sold unfit for its intended use or diminish its fitness to such an extent that the vendee would not have acquired it or would have given a lower price. The requisites to recover are: (a) the defect must be hidden; (b) the defect must exist at the time the sale was made; (c) the defect must ordinarily have been excluded from the contract; (d) the defect must be important; and (e) the action must be instituted within the statute of limitations. The Court applied this doctrine by requiring strict proof that the defect existed at the time of sale, which the respondents failed to provide due to the delay in testing and lack of chain of custody.
• Implied Warranty in Sale of Animal Feeds — There is an implied warranty that animal feeds are reasonably fit and suitable for the purpose for which both parties contemplated their use. The Court found this warranty was not breached because the respondents failed to prove the feeds were defective upon delivery.
• Burden of Proof in Products Liability — To prove liability based on breach of implied warranty, the buyer must establish: (1) injury sustained because of the product; (2) the injury occurred because the product was defective or unreasonably unsafe; and (3) the defect existed when the product left the seller's hands. The Court held that the respondents failed to satisfy the third requirement, as the three-month gap and lack of identity between tested and consumed feeds broke the causal link.

• "A difference of approximately three months enfeebles the respondents’ theory that the petitioner is guilty of breach of warranty by virtue of hidden defects. In a span of three months, the feeds could have already been contaminated by outside factors and subjected to many conditions unquestionably beyond the control of the petitioner."
• "Mere sickness and death of the chickens is not satisfactory evidence in itself to establish a prima facie case of breach of warranty."
• "The respondents’ case of breach of implied warranty was fundamentally based upon the circumstantial evidence that the chickens and hogs sickened, stunted, and died after eating Nutrimix feeds; but this was not enough to raise a reasonable supposition that the unwholesome feeds were the proximate cause of the death with that degree of certainty and probability required."

• Swift & Company v. Redhead, 122 N.W. 140 (1909) — Cited as basis for the implied warranty that animal feeds are reasonably fit for the purpose contemplated by the parties.
• Lee Worden v. John Gangelhoff, 241 N.W.2d 650 (1976) — Cited for the three elements a buyer must establish to prove liability for breach of implied warranty.
• Poovey v. International Sugar Feed No. 2 Co., 133 S.E. 12 (1926) — Followed. Mere sickness and death of animals is not satisfactory evidence in itself to establish a prima facie case of breach of warranty.
• Edgar Green v. Ralston Purina Co., 376 S.W.2d 119 (1964) — Followed. Circumstantial evidence of sickness and death after consuming feeds is insufficient to raise a reasonable supposition that the feeds were the proximate cause of death with the required certainty.

• Article 1561, Civil Code — Renders the vendor responsible for hidden defects that render the thing sold unfit for its intended use or diminish its fitness. Applied to determine the seller's liability for the alleged contaminated feeds.
• Article 1566, Civil Code — Holds the vendor responsible for hidden faults or defects even if unaware of them. Applied in conjunction with Art. 1561 to assess liability.
• Article 1567, Civil Code — Provides the remedies for violations of warranty against hidden defects: accion redhibitoria (withdrawal from the contract) or accion quanti minoris (proportionate reduction of price), with damages in either case. Cited to note the proper remedies, even though the breach was not proven.
