Chang v. Citibank

Background

Ching P. Chang, who is over 80, held a deposit account at Citibank. On June 10, 2022, a person identifying himself as a Citibank employee named “John” contacted Chang. Chang gave that person remote access to his computer and entered his debit-card number and password. A payee named Xu Gao was then added for a $49,000 wire transfer.

Citibank evaluated the transaction for fraud, determined that the request came from a Windows device associated with Chang, emailed him a fraud alert, and received a response indicating no fraud. Citibank also called the phone number on file, but the person who answered did not respond. Chang later told Citibank that he had not authorized the transaction. Citibank tried but could not retrieve the funds and did not reimburse Chang.

Chang filed an arbitration demand against Citibank on August 16, 2023. The arbitrator dismissed claims under the Electronic Funds Transfer Act and for elder abuse. The arbitrator found that the Electronic Funds Transfer Act claim failed because Chang had given “John” remote access to his account, that there was no evidence Citibank knew about or assisted in “John’s” fraudulent conduct, and that Citibank had used reasonable security measures in attempting to detect fraud.

Chang filed this federal lawsuit on May 14, 2025. His six-count complaint asserted financial elder abuse, fraud, negligence, breach of contract, a claim under California’s Unfair Competition Law, and violations of the Electronic Fund Transfer Act. He also alleged misconduct during the arbitration, including an aggressive deposition, inadequate responses to discovery requests, and false evidence submitted to the arbitrator. He argued that these circumstances and later communications equitably extended the deadline for seeking to overturn the arbitration award.

Analysis

Deadline for challenging the arbitration award. Under the Federal Arbitration Act, a party must serve notice of a motion to vacate an arbitration award within three months after the award is filed or delivered. California law sets a 100-day deadline. The court found that the award was issued and served on October 21, 2024, and that Chang filed his complaint 205 days later. The court therefore found his challenge untimely and denied his petition to vacate the arbitration award.

The court rejected Chang’s arguments that the deadlines were extended by his request to the American Arbitration Association for reconsideration or by Citibank’s statement that it would review his complaint to the Office of the Comptroller of the Currency. The arbitration was closed three days after Chang requested reconsideration, and the court found no authority establishing that Citibank’s internal review process extended the deadline.

Claim preclusion. The court also applied res judicata, also called claim preclusion. This doctrine bars a later lawsuit involving claims that were raised or could have been raised in an earlier proceeding when there are the same claims, a final judgment on the merits, and the same parties or legally equivalent parties. The court found that the arbitration award qualified as a final judgment on the merits and that the parties were the same.

Although Chang asserted fraud, negligence, breach of contract, and unfair-competition claims that he had not separately asserted in arbitration, the court found that those claims arose from the same underlying events considered by the arbitrator: the alleged deception, the $49,000 transfer, Citibank’s fraud alert and response, Chang’s later notification to Citibank, and the unsuccessful effort to retrieve the money. The court dismissed the remaining claims as precluded by the arbitration award.

Amendment and disposition

The court found that amendment would be futile and denied Chang leave to amend. It concluded: “Defendant’s motion to dismiss is granted with prejudice.” Thus, the court denied the petition to vacate the arbitration award, dismissed the remaining claims as precluded, denied leave to amend, and granted Citibank’s motion to dismiss with prejudice.
