He used the internal hotline, senior staff lost their jobs - then the bank turned on him
A former quality assurance associate at Sumitomo Mitsui Banking Corporation says the bank pushed him out after he reported regulatory reporting fraud - then dressed the firing up as restructuring.
Charles Lamus filed his complaint on May 5, 2026, in the Southern District of New York. He sues under the Sarbanes-Oxley Act and New York Labor Law § 740, the state's whistleblower statute.
The setting matters. According to the filing, the bank entered a written agreement with the Federal Reserve Bank of New York in April 2019 after examiners flagged anti-money laundering and Bank Secrecy Act problems. To clean things up, the complaint says, the bank brought in roughly 200 consultants, most assigned to Know Your Client (KYC) and quality assurance testing.
Lamus joined that effort in May 2021 at $125,000 a year, became a permanent employee in June 2022, and was earning $131,300 by 2024 after two merit raises.
He says he quickly noticed a pattern. Between five and 20 findings each month, the complaint alleges, were flagged "Material" by a primary analyst, confirmed by a secondary analyst, verified by a team lead and approved by the QA director - then deleted or downgraded to "Immaterial" at the final stage.
The complaint says his team leader and director agreed something was wrong and pointed to QA Executive Director Yvette Irving. According to the filing, his director told him Irving and KYC Executive Director Bob Benson were working to "Massage the number of Material fails" each month so the bank would hit a 90% pass-rate target meant to show the Federal Regulator improvement.
Lamus says he was shown internal text messages. In one dated April 1, 2021, the filing alleges Irving wrote, "I talked to [Mr. Benson] def a fail but don't submit it until next [week], think another 3 HR files came in," and "Thanks he wants to take the hit next [week], all hell will break lose if there pass rate goes under 80% if it does let it be next week mentally no one can take the senior beat down." In another dated July 21, 2021, she allegedly wrote, "[Mr. Benson] said to hold on materials until next week, we are at 90% but let's see how many total we have to submit."
On November 16, 2022, Lamus submitted a formal whistleblower complaint through the bank's internal "Speak Up" portal. The bank brought in the law firm Cleary Gottlieb Steen & Hamilton LLP to investigate. According to the complaint, three senior figures - Irving, Benson, and Managing Director Andre Burrell - were later terminated.
Then, Lamus alleges, things turned on him.
He says he was iced out of meetings, dropped from email chains, and pulled off the most complex KYC testing. He claims Managing Director Kevin Choi mocked him in front of colleagues with lines like, "Is this a QA finding or a [Plaintiff] finding?" According to the filing, those comments never made it into the official meeting minutes.
In late November 2023, the complaint alleges, his team lead told him the new QA executive director, So-Ok Kim, had submitted his name for termination as part of "Target Operating Model" cuts - and that Chief Compliance Officer Lissette Lieberman blocked it because she wanted to "Avoid a lawsuit." His director allegedly confirmed the same account on December 4, 2023.
Lamus stayed. From April through October 2024 he ran the QA KYC Americas Testing team and, according to the complaint, brought it to 80% complete after months of backlog. He says he took no vacation. He alleges his May 2024 bonus was $10,000 - the same amount he had received the year before in a smaller role - and that in August 2024 he was told a promotion might be reconsidered in another seven to eight months.
On November 4, 2024, Lamus says, Kim called him and terminated him, telling him "the Bank was going in a different direction." He alleges the bank offered $12,000 in severance contingent on a release of claims. He also alleges the bank kept advertising for substantially similar Compliance Monitoring & Testing and Quality Assurance roles after his exit, which he argues undercuts the restructuring rationale.
For HR leaders, the filing reads as a case study in what can go wrong after a whistleblower complaint succeeds. A worker used the official channel. An external investigation followed. Three named senior figures were let go. And then, on the plaintiff's account, the same worker who triggered the cleanup found himself sidelined, passed over for promotion, and quietly steered toward a "restructuring" exit.
The two "Avoid a lawsuit" comments, attributed by Lamus to two separate managers, are the kind of internal remark that lands hard in a retaliation case - and the kind HR teams are usually trained never to put in writing, let alone say out loud.
Lamus is seeking reinstatement, back pay with interest, compensatory and punitive damages, and attorney's fees. He has demanded a jury trial.
The allegations have not been tested in court. Sumitomo Mitsui Banking Corporation has not yet filed a response, and no court has ruled.
