Acme Markets Inc. v. Federal Armored Express Inc.

Acme Markets Inc. (plaintiff) contracted with Federal Armored Express Inc. (defendant) for armored-car service, with Federal agreeing to reimburse Acme for 'service-related losses.' When a loss occurred, Federal argued that a requirement that Acme provide a receipt was a condition precedent to Federal's obligation to pay, excusing it entirely.

Whether a condition precedent must be strictly enforced under Pennsylvania law where doing so would cause a disproportionate forfeiture and the condition was not a material part of the contract.
