After procuring a checking account, the depositor issued several checks. He was surprised to learn later that they had been dishonored for insufficient funds. Investigation disclosed that deposits made by the depositor were not credited to its account. Is the bank liable for damages?
Yes, the depositor expects the bank to treat his account with utmost fidelity, whether such account consist only of a few hundred pesos or of millions. The bank must record every single transaction accurately, down to the last centavo, and as promptly as possible. This has to be done if the account is to reflect at any given time the amount of money the depositor can dispose of as he sees fit, confident that the bank will deliver it as and to whomever he directs. A blunder on the part of the bank, such as the dishonor of the check without good reason, can cause the depositor not a little embarrassment if not also financial loss and perhaps even civil and criminal litigation.
