48 Cal.App.5th 952
Cal. Ct. App.2020Background
- Kurtz‑Ahlers (plaintiff) hired freelance bookkeeper Elizabeth Mulder, who for nearly five years directed the company’s tax‑payment checks to a DBA she added to her personal Bank of America account, then deposited them there, diverting over $700,000.
- Both Kurtz‑Ahlers and Mulder held accounts at Bank of America; Mulder endorsed the checks and deposited them into the account titled “Income Tax Payments.”
- Mulder was later convicted of federal crimes and imprisoned; Kurtz‑Ahlers submitted a claim to the Bank for the losses which the Bank denied.
- Kurtz‑Ahlers sued Bank of America for negligence (alleging the Bank should have detected and warned of the fraud after Mulder added the suspicious DBA); the Bank obtained summary adjudication on a conversion claim and moved for nonsuit on negligence grounds.
- The trial court granted nonsuit, holding the Bank owed no duty to monitor another depositor’s account; the Court of Appeal affirmed.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the Bank had a duty to investigate based on Mulder’s DBA “Income Tax Payments” (Sun ’n Sand exception) | DBA was an objectively suspicious “red flag” triggering the Bank’s duty of inquiry under Sun ’n Sand | Sun ’n Sand applies only where a third party attempts to negotiate checks payable to someone else; here checks were payable to the account in which they were deposited | Court: Sun ’n Sand does not apply because Mulder deposited checks payable to the payee/account; no duty to inquire on this basis |
| Whether courts should recognize a new duty requiring banks to monitor other depositors’ accounts for suspicious activity | Court should impose an intra‑bank monitoring duty to protect depositors when bank is uniquely positioned to detect fraud | Imposing such a duty would conflict with privacy, efficiency, and payment‑processing rules and impose undue burdens; existing law rejects policing duty | Court: Declines to create new duty; public policy and precedent preclude imposing an intra‑bank monitoring obligation; nonsuit affirmed |
