G.R. No. 188412 ; November 22, 2010
CITIBANK, N.A., Petitioner, vs. ATTY. ERNESTO S. DINOPOL, Respondent.

FACTS

Respondent Atty. Ernesto Dinopol availed of petitioner Citibank’s “Ready Credit” facility, granting him a credit line of ₱30,000.00. He received a checkbook with a letter stating the account was “ready to use.” Citibank subsequently billed him for documentary stamp and membership fees, and later for interest and late payment charges, which he paid. On March 6, 1997, Dinopol issued a ₱30,000.00 check from this account. Upon presentment, it was dishonored for “Drawn Against Insufficient Funds” (DAIF). Citibank defended the dishonor, arguing Dinopol’s available credit was reduced by an outstanding ₱58.33 from unpaid interest and charges, rendering the check amount beyond his limit.
Dinopol filed a damages suit, alleging gross negligence and bad faith. He claimed Citibank failed to fully disclose account terms, never provided the essential Customer Guidebook, and gave him a “go signal” when he inquired about issuing the check without advising him of the minimal outstanding balance that would cause dishonor.

ISSUE

Whether Citibank is liable for damages due to its failure to exercise the requisite degree of diligence in handling Dinopol’s Ready Credit Account, leading to the wrongful dishonor of his check.

RULING

Yes, Citibank is liable. The Supreme Court affirmed the findings of the lower courts that Citibank failed to exercise the highest degree of diligence required of banks. The fiduciary nature of banking demands meticulous care, utmost good faith, and full disclosure to clients. Citibank’s failure to provide Dinopol with the Customer Guidebook containing crucial terms on fees and penalties constituted a lack of transparency. More critically, when Dinopol inquired before issuing the check, the bank gave an affirmative response without warning him that a minuscule outstanding balance of ₱58.33 would consume his credit line and cause dishonor. This balance was not even due for payment at the time the check was issued. The bank’s inaction, despite having the opportunity to alert Dinopol and avoid dishonor over a trivial amount, amounted to bad faith. This negligence directly caused the check’s dishonor, tarnishing Dinopol’s reputation as a lawyer and causing him humiliation. While the Supreme Court modified the appellate court’s award by reducing moral damages to ₱100,000.00, it upheld awards for exemplary damages and attorney’s fees to emphasize the bank’s culpability and to serve as a deterrent, reinforcing the stringent standards of care expected in the banking industry.
