Bank Not Liable for Branch Manager's Unauthorized Guarantee: UCPB v. Planters Products

The Supreme Court's 2012 ruling in United Coconut Planters Bank v. Planters Products, Inc. clarifies a critical question in Philippine banking law: when is a bank responsible for its branch manager's unauthorized acts? The case involved a fertilizer manufacturer that lost P200,000 when a UCPB branch manager connived with a client to guarantee a loan payment the bank never authorized. The Court's answer protects banks from liability when officers act beyond their authority, but it also highlights the risks of dealing with bank officers who appear to act on their own.

The Facts of the Case

Planters Products, Inc. (PPI), a fertilizer manufacturer, agreed to deliver fertilizers to Janet Layson, who claimed she had an approved P200,000 loan from UCPB's Iloilo Branch. Layson executed documents called "pagares" on the back of UCPB promissory notes, assigning the loan proceeds to PPI as payment. Branch manager Gregory Grey signed the documents, stating: "Assignment accepted and payment unconditionally guaranteed within sixty (60) days."

The next day, however, Grey released the P200,000 loan proceeds directly to Layson—with her connivance—instead of turning them over to PPI. When PPI presented the documents for collection, UCPB denied liability, claiming Grey exceeded his authority. The bank noted that Grey's lending authority was limited to P10,000 for unsecured loans, and any larger loan required unanimous approval from the Branch Credit Committee.

The Legal Issue

The central question was whether UCPB was bound by Grey's undertaking to guarantee payment of Layson's fertilizer purchases. PPI argued that UCPB, as a corporation, was liable because it held Grey out as possessing authority to act for the bank.

The Supreme Court's Ruling

The Court ruled in favor of UCPB, reversing the Court of Appeals and reinstating the trial court's decision absolving the bank from liability.

First, the Court examined Grey's signature on the pagares. He signed simply as "GREGORY GREY, Manager"—not in the bank's name and without indicating he was acting on behalf of UCPB. The undertaking's wording made no reference to the bank at all. The Court concluded Grey was acting in his personal capacity.

Second, the Court emphasized that Grey's undertaking was a guarantee—a highly regulated banking transaction. Under Republic Act 8791 (the General Banking Act), bank guarantees are contracts that bind the bank and may only be entered into with authority from the bank's board of directors. No such authorization existed in this case.

Third, the evidence showed Grey connived with Layson to defraud PPI. Grey approved the assignment, then released the loan proceeds to Layson the very next day, knowing the funds were supposed to go to PPI.

The Court distinguished this case from situations where corporations are liable for their officers' acts within apparent authority. Here, Grey's guarantee was not part of UCPB's usual banking transactions, and PPI had no right to expect a branch manager to issue such a guarantee without board authorization.

Practical Takeaways

• Banks are not automatically liable for everything their branch managers sign. A manager's signature in a personal capacity, without bank authorization, does not bind the bank—especially for transactions like guarantees that require board approval.

• Guarantees are strictly regulated. Under the General Banking Act, bank guarantees require formal authorization. Third parties should verify that a bank officer has actual authority before relying on any guarantee.

• Dealings with bank officers should be documented through proper channels. If a transaction involves a bank's credit or guarantee, insist on documentation that clearly identifies the bank as a party and shows board approval where required.

• Connivance between a bank officer and a client can shield the bank from liability. When an officer acts in cahoots with a client to defraud a third party, the bank may escape liability if the officer exceeded his authority.

• Lending limits matter. Banks impose internal ceilings on officers' lending authority. Transactions beyond those limits, without proper committee approval, are unauthorized and may not bind the bank.
