In Jonathan Jung v. Discover Bank, Judge Breyer granted Discover’s dismissal motion, ending the Electronic Funds Transfer Act claim but allowing amendment of two others.
Jonathan Jung’s claims against Discover Bank were affected. The EFTA claim was dismissed without leave to amend, while the California Commercial Code and Unfair Competition Law claims were dismissed with leave to amend within 30 days. The opinion also concerns the proposed class action Jung filed, but it does not rule on class certification.
What happened
In Jonathan Jung v. Discover Bank, Jonathan Jung alleged that a fraudster used information obtained from his wife to transfer $110,000 from their joint Discover savings account. After Discover refused to reimburse him, Jung filed a proposed class action under the federal Electronic Funds Transfer Act, California’s Commercial Code, and California’s Unfair Competition Law.
The court ruled that the Electronic Funds Transfer Act does not cover consumer wire transfers and dismissed that claim without leave to amend. It dismissed the Commercial Code claim because Jung did not adequately allege that Discover used an unreasonable security procedure, but allowed him to amend that claim. It also dismissed the Unfair Competition Law claim because Jung did not allege that he lacked an adequate legal remedy, while allowing amendment.
Judge Charles R. Breyer granted Discover’s motion to dismiss. Jung may amend the Commercial Code and Unfair Competition Law claims within 30 days; the order states that failing to amend on time could result in dismissal with prejudice.

Background
Jonathan Jung and his wife, Karen Chiu, had a joint online savings account with Discover. According to the amended complaint, the account had been breached several times between October 2023 and December 2024. On December 5, 2024, a fraudster who appeared to be calling from Discover’s official phone number persuaded Chiu to verify her identity through Socure, a third-party vendor used by Discover. Jung then received notice that a $110,000 wire transfer had been initiated from the account.
Jung promptly disputed the transfer. Discover closed the account, opened a replacement account, investigated, and determined that the wire was sent to a Bank of America account. Discover refused to reimburse Jung, stating that the transaction had passed its internal security measures. Jung filed a proposed class action alleging violations of the Electronic Funds Transfer Act (EFTA), California’s Commercial Code, and California’s Unfair Competition Law (UCL). After Jung amended his complaint in response to Discover’s first dismissal motion, Discover filed another motion under Federal Rule of Civil Procedure 12(b)(6), which permits dismissal for failure to state a legally sufficient claim.
EFTA claim
Jung alleged that the wire transfer was an unauthorized electronic fund transfer under the EFTA. The court held that the EFTA does not apply to consumer wire transfers. It relied on the statute’s exclusion of certain transfers made through services transferring funds held at banks and on the implementing regulation’s exclusion of wire and similar transfers. The court therefore dismissed the EFTA claim without leave to amend.
California Commercial Code claim
Jung alleged that the wire transfer was a payment order that Discover had to refund. Under the California Commercial Code, a bank generally bears the loss if a payment order was unauthorized and was not verified through a commercially reasonable security procedure that the bank followed in good faith.
The court found Jung’s allegation that the payment order was unauthorized adequate at the motion-to-dismiss stage. It distinguished a case in which an employee knowingly confirmed a transfer after being deceived by a fraudster; here, Jung did not know about the wire transfer, and Chiu did not think she was authorizing one.
However, the court found Jung’s allegation that Discover did not maintain or apply a reasonable security procedure conclusory and insufficient. Jung did not provide enough information about the customer’s usual payment activity, Discover’s security measures, alternative procedures, or comparable security practices to support an inference that Discover’s procedures were commercially unreasonable. The court dismissed the Commercial Code claim with leave to amend if Jung could add allegations explaining why Discover’s security procedures were unreasonable under the statute.
Unfair Competition Law claim
Jung alleged that Discover violated both the unlawful and unfair prongs of California’s Unfair Competition Law. The court addressed only Discover’s argument that Jung was not entitled to equitable relief. Because the UCL provides equitable remedies, the court said Jung had to plead that he lacked an adequate legal remedy. The complaint alleged economic harm but did not explain why legal remedies were inadequate. The court dismissed the UCL claim with leave to amend if Jung could add those allegations and directed him to consider Discover’s other dismissal arguments.
Disposition
The court granted Discover’s motion to dismiss. It dismissed the EFTA claim without leave to amend and dismissed the Commercial Code and UCL claims with leave to amend. Jung had 30 days to amend the complaint if he wished to do so. The order states that failure to amend on time could result in dismissal with prejudice.
