G.R. No. L-27058 January 17, 1973
AMERICAN EXPRESS COMPANY, INC., plaintiff-appellee, vs. CIRIO H. SANTIAGO, defendant-appellant.

FACTS

Plaintiff-appellee American Express Company, a duly registered foreign corporation, operates a credit card system. Defendant-appellant Cirio H. Santiago applied for and was issued an American Express Credit Card in New York in 1959. Using this card before its cancellation in 1961, Santiago incurred charges totaling $15,297.53 for purchases and services obtained from various establishments in multiple foreign countries. After demands for payment were refused, American Express filed a collection suit.
The defendant’s main defense was that American Express was not the real party-in-interest. He argued the credit card merely introduced him to the establishments, which should have been the proper parties to sue for collection. The parties entered into a stipulation of facts, and the plaintiff presented evidence, including a deposition from its employee, detailing the credit system’s operation.

ISSUE

Whether American Express Company is the real party-in-interest with a valid cause of action to collect the unpaid credit card charges from Santiago.

RULING

Yes, the Supreme Court affirmed the lower court’s decision, holding American Express as the proper party to sue. The legal logic is grounded in the contractual relationships established by the credit card system. The evidence, particularly the uncontroverted deposition, established the operational mechanics: establishments appointed by American Express extend credit to cardholders, bill American Express directly for the charges, and are reimbursed by the company. American Express, in turn, bills the cardholder. By paying the establishments, American Express became subrogated to their rights, making it Santiago’s direct creditor.
The Court found the appellant’s procedural objections to the deposition’s admission unmeritorious. The minor deviation in the filing procedure—where plaintiff’s counsel, at the Department of Foreign Affairs’ request, delivered the sealed deposition to the Clerk of Court—did not compromise its integrity or admissibility, especially since the core fact of indebtedness was undisputed. The only substantive issue was the identity of the proper plaintiff, which was conclusively resolved by the evidence demonstrating American Express’s role as the paying entity and subsequent biller. The judgment was modified only as to the exact principal amount and the directive for payment in Philippine currency at the prevailing exchange rate.
