Background

Mark Sundahl alleged that nearly $5,900 in unauthorized transactions followed the loss or theft of his Direct Express debit card. He said he promptly reported the card missing and told Comerica Bank and Conduent that later charges were fraudulent.

His amended complaint asserted financial elder abuse based on a direct taking and on assistance to the unknown fraudster. The defendants moved to dismiss after an earlier ruling had identified deficiencies in those theories.

The Court’s Holding

The court dismissed the financial-elder-abuse claim without leave to amend. Allegations that the defendants should have recognized suspicious transactions amounted at most to constructive knowledge, not the actual knowledge required for liability based on assisting another person’s taking.

The complaint also did not plausibly allege that the defendants retained property for a wrongful use or intentionally provided substantial assistance or encouragement to the fraud. Because an earlier amendment did not cure those defects and further amendment appeared futile, dismissal was final as to that claim.

Key Takeaways

  • A bank’s constructive notice of suspicious activity is insufficient for aiding financial elder abuse.
  • A customer’s fraud report does not by itself establish that the institution actually knew the transactions were fraudulent.
  • The complaint must allege substantial assistance or encouragement, not merely processing or failing to stop transactions.
  • Repeated inability to plead actual knowledge can justify dismissal without leave to amend.

Why It Matters

Financial institutions are not automatically liable under California’s elder-abuse statute whenever disputed transactions continue after a warning. Plaintiffs need specific facts showing actual knowledge and intentional assistance, while banks should preserve the timing and substance of fraud reports and investigative decisions.
