Bank of the Philippine Islands v. The Hon. Court of Appeals (Seventh Judicial)

Summary

This landmark banking case involved forged cashier's checks totaling P2.4 million where an impostor impersonated money market client Eligia G. Fernando. The impostor convinced BPI to preterminate Fernando's placement, obtained checks, then opened a CBC account and withdrew the funds. Both banks were found negligent - BPI for inadequate verification procedures and CBC for suspicious account opening practices and allowing large immediate withdrawals. The Supreme Court applied comparative negligence, allocating the loss 60% to BPI and 40% to CBC, establishing important precedent for inter-bank liability in fraud cases involving the clearing system. The decision balanced the Negotiable Instruments Law's forgery provisions with practical banking operations and emphasized both banks' duty of extraordinary diligence in preventing fraud.
