The court explains:
The usual method by which Hyman-Michaels, in Chicago, got the payments to the Banque de Paris in Geneva was to request the Continental Illinois National Bank and Trust Company of Chicago, where it had an account, to make a wire transfer of funds. Continental would debit Hyman-Michaels' account by the amount of the payment and then send a telex to its London office for retransmission to its correspondent bank in Geneva-Swiss Bank Corporation--asking Swiss Bank to deposit this amount in the Banque de Paris account of the Pandora’s owner.
To change the case into a breach of contract case, assume H-M a contract with Swiss Bank and that the contract was breached by the delay in the wire transfer.
