Alvin Tan v. Court of Appeals

Summary

Alvin Tan sold a Mercedes Benz to Arthur Dy Guani through a lease-financing arrangement, allegedly misrepresenting that customs duties were paid by showing photocopies of payment documents. When the Bureau of Customs later seized the vehicle for non-payment of duties, Dy Guani sued for fraud and damages. The Regional Trial Court and Court of Appeals found Tan liable, awarding moral damages and attorney's fees. However, the Supreme Court reversed the decision, dismissing the case on procedural grounds. The Court held that Dy Guani, acting merely as agent of Guani Marketing corporation in the transaction, was not the real party in interest and thus lacked standing to sue. The case establishes the fundamental principle that only the real party in interest - the party who stands to be benefited or injured by the judgment - can maintain a civil action, reinforcing corporate personality and agency principles in Philippine civil procedure.
