The Railway Express Agency delivered a shipment of goods to Lorraine. Payment for the goods was made with a certified check, payable to the order of the Railway Express Agency. The check was drawn by Lorraine on the First National Bank of Detroit. Thereafter, the bank refused to pay the check when presented by Railway Express, the holder, because the bank had become insolvent and stopped doing business. The Railway Express Agency sued Lorraine. She claimed that she was not liable on the check because it was certified. Is she correct?
