E. Zobel v. The Court of Appeals

Summary

This Supreme Court case clarified the distinction between contracts of guaranty and surety under Philippine civil law. E. Zobel Inc. sought to escape liability on a continuing guaranty by arguing that the bank's failure to register a chattel mortgage extinguished their obligation under Article 2080 of the Civil Code. The Supreme Court held that despite being titled 'Continuing Guaranty,' the contract actually created a surety relationship based on its terms obligating Zobel as an 'original promissor.' Since Article 2080 applies only to guarantors and not sureties, and because Zobel contractually waived reliance on collateral security, their liability was not extinguished. The decision reinforced that contract interpretation depends on the parties' actual intention and terms, not merely the document's title, and established important precedent distinguishing guaranty from surety obligations in commercial lending contexts.
