Aetna Casualty & Surety Co. v. Phoenix National Bank & Trust Co.

Background

A national bank paid thirty-nine checks drawn on a corporate depositor’s account; many endorsements were forged or amounts were raised by the depositor’s vice president, Fulton. The bank charged the payments to the depositor’s account, sent monthly statements with cancelled checks, and later recredited the depositor about $5,512.72 after being notified of the forgeries. The bank held an indemnity bond from a bond issuer, who agreed to cover losses from forged or raised checks for a premium. The bank then asked the bond issuer to pay; the issuer argued the depositor’s negligence and the bank’s later crediting and release of claims relieved it of liability.

Reasoning

The core question was whether the bank’s later actions—crediting its depositor and abandoning claims against the wrongdoers—defeated the bond issuer’s obligation to indemnify. The Court explained that an indemnity contract necessarily includes the issuer’s right to step into the bank’s position to pursue recovery from others who are liable. By recrediting the depositor and relinquishing claims without preserving the issuer’s recovery rights, the bank impaired the issuer’s subrogation privilege and thus discharged the issuer from liability. The Court reversed the lower court’s view that the bank’s loss was fixed at payment and that later events were immaterial.

Real world impact

Banks that accept indemnity bonds cannot give up or extinguish underlying claims against customers or endorsers without jeopardizing the bond issuer’s duty to pay. Bond issuers are protected when indemnitees surrender recovery rights; disputes over who ultimately bears loss may depend on whether recovery rights were preserved.
