Chua vs. Bank of Commerce

A notarized document's presumption of regularity is a disputable presumption that can be overcome by clear and convincing evidence to the contrary, such as consistent denial of execution, glaring irregularities in the notarization process, and lack of a rational basis for the signatory's obligation. For valid continuing suretyship agreements, the surety's liability attaches to future loans, and a contractual waiver of notice and demand is binding.

Interbrand Logistics secured a credit line from Bank of Commerce. As a condition, the bank required CSAs from Interbrand's key officers, majority shareholders, and Gil Chua (who claimed no connection to the company). Interbrand subsequently obtained multiple loans evidenced by promissory notes but eventually defaulted.

• Filed in RTC (Makati City) as a complaint for sum of money.
• The RTC initially absolved Chua but later reversed itself, holding all sureties liable.
• The CA affirmed the RTC's modified decision.
• Elevated to the SC via consolidated Petitions for Review on Certiorari.

• Interbrand's board authorized securing a PHP 150M loan from Bank of Commerce, with CSAs to be signed by its officers, shareholders, and Gil Chua.
• CSAs were executed and notarized. They contained a waiver of, among others, notice of acceptance and presentment/demand.
• Interbrand received the loan but later defaulted.
• The bank filed a complaint. Four years later, it amended the complaint to substitute a new set of eight matured promissory notes (for the same total principal) for the original seven.
• Chua denied signing the CSA, appearing before the notary, or having any stake in Interbrand.
• Interbrand et al. (other sureties) did not present evidence but argued the CSAs lacked consideration as they pre-dated the sued-upon promissory notes, and that the amended complaint introduced a new cause of action.

• Chua (G.R. No. 263632):
  • The presumption of regularity of his notarized CSA was overcome by clear and convincing evidence of forgery and irregular notarization.
  • He had no connection to Interbrand, making it illogical for him to assume its debts.
  • The bank failed to present the notary or witnesses to prove due execution.
• Interbrand et al. (G.R. No. 264110):
  • Their CSAs were void for lack of consideration because they were executed before the specific promissory notes sued upon.
  • The amended complaint was improper as it constituted an entirely new cause of action, requiring a separate suit.
  • They were not given prior demand before being sued as sureties.

• Bank of Commerce:
  • The notarized CSAs carry a presumption of regularity, which Chua failed to overcome with clear and convincing evidence.
  • The CSAs are continuing suretyships, expressly covering future loans, so consideration exists.
  • The amendment of the complaint was proper under the Rules; the cause of action (collection of sum of money based on the CSAs) remained the same.
  • The CSAs contain a valid waiver of demand, which the sureties signed.

• Procedural Issues: Whether the trial court erred in admitting the amended complaint that substituted an entirely new set of promissory notes.
• Substantive Issues:
  1. Whether the presumption of regularity of Chua's notarized CSA was overcome by evidence.
  2. Whether Interbrand et al. are liable under CSAs executed before the specific promissory notes sued upon.
  3. Whether prior demand on the sureties was necessary.

• Procedural: The SC found no reversible error. While the "amended complaint" was effectively a new complaint superseding the original, it was filed before pre-trial and did not prejudice the defendants. Given the case's 14-year delay, the defendants' bad faith in causing delay, and the fact they waived presentation of evidence, requiring a new suit would be an injustice.
• Substantive:
  1. Yes, as to Chua. The SC found the presumption of regularity was overcome. Evidence showed: (a) Chua had no logical reason to guarantee Interbrand's debt; (b) he consistently denied signing; (c) the bank's witness had no personal knowledge and no signature card; (d) the notary and witnesses were not presented; (e) patent irregularities existed (same witnesses for documents notarized on the same day in different cities).
  2. No, as to Interbrand et al. The CSAs are continuing suretyships. Their nature is to secure present and future indebtedness. The dates of execution relative to the promissory notes are irrelevant.
  3. No. The CSAs contained a clear and valid waiver of "presentment, demand protest and notice of dishonor." This stipulation is the law between the parties.

• Presumption of Regularity of Notarized Documents — A notarized document is a public document that enjoys the presumption of regularity. However, this is a disputable presumption that can be overturned by clear and convincing evidence showing irregularity or lack of due execution. The SC applied this by detailing the evidence that successfully impeached Chua's CSA.
• Continuing Suretyship Agreement — A contract where a surety guarantees not only existing but also future obligations of the principal debtor, up to a specified limit. It avoids the need for a new surety contract for each loan transaction. The SC applied this to hold Interbrand et al. liable for the later promissory notes.
• Waiver of Demand in Suretyship — A surety may validly waive the requirement of prior demand or notice of default through a stipulation in the contract. Such a waiver is binding and enforceable. The SC applied this to reject the defense of lack of prior demand.

• "Although the notarization of the subject CSA carries with it the presumption of regularity, it is not the intention nor the function of the notary public to validate and make it binding when such CSA, in the first place, was never intended to have any binding legal effect upon Chua."
• "The essence of a continuing suretyship agreement is to anticipate a series of commercial transactions with projected principal debtors already equipped with a suretyship agreement to cover present and future loans."
• "Justice delayed is justice denied—an old adage that must be realized and must be given meaning by the Court."

• Dela Rama v. Papa — Cited to support the principle that evidence challenging a notarized document can shift the burden of evidence to the party relying on it to prove its due execution, especially when the notary is not presented.
• Lim v. Security Bank Corp. — Cited to affirm the validity and binding effect of a waiver of demand in a continuing suretyship agreement.
• Tan v. First Malayan Leasing and Finance Corp. — Cited to explain the nature of a surety's liability as principal, direct, and joint and several, distinct from a mere guarantor.
• Nacar v. Gallery Frames — Cited for the imposition of legal interest (6% per annum) on the final monetary award from the date of finality until full payment.

• Article 1169, Civil Code — On the necessity of demand for delay to occur (raised by petitioners but rendered moot by the waiver).
• Article 2229, Civil Code — On penalty clauses as indemnity for damages in monetary obligations.
• Article 2208, Civil Code — On the award of attorney's fees when a defendant acts in gross and evident bad faith in refusing to satisfy a plainly valid claim.
• Rule 10, Section 8, Rules of Court — Provides that an amended pleading supersedes the original one.
