On November 9, Jane Jones writes a check for $500 payable to Ralph Rodgers in payment for goods to be received later in the month. Before the close of business on the ninth, Jane notifies the bank by telephone to stop payment on the check. On Monday, December 19, Ralph gives the check to Bill Briggs for value and without notice.
On the twentieth, Bill deposits the check in his account at Bank A. On the twenty-first, Bank A sends the check to its correspondent, Bank B. On the twenty-second, Bank B presents the check through the clearinghouse to Bank C.
On the twenty-third, Bank C presents the check to Bank P, the payor bank. On Wednesday, December 28, the payor bank makes payment of the check final. Is Jane Jones' stop payment order effective against the payor bank? Explain.
