Answer:
The plaintiff bank wins the case
Explanation:
The banks may provide overdraft services to it's customers and pay check even in the case of unavailability of funds in their accounts. An overdraft creates obligation on the customer to pay later in future.
In this case the defendant did not report the loss or theft of the check until the bank finally contacted for paying overdraft. The plaintiff bank could pay the properly presented check even if it created an overdraft. Although it is up to the bank that it may consider the check not to be properly payable and deny paying without risk of liability for wrongful dishonour, it does not prevent the bank from paying the overdraft check alternatively.
