About Whistleblower Attorney Stephen M. Kohn

Stephen M. Kohn is widely recognized as one of the nation’s leading qui tam and whistleblower attorneys. He won the largest ever individual whistleblower reward/qui tam payment for UBS whistleblower Bradley Birkenfeld ($104 million reward for Mr. Birkenfeld). His record of winning whistleblower cases dates back to 1984, and he was peer-review rated by the National Law Journal as one of the 50-top plaintiff’s lawyers in the United States, the only whistleblower rights lawyer to achieve this distinction. His successful advocacy has resulted in landmark precedents in whistleblower and qui tam law.

Kohn helped draft key whistleblower legislation and regulatory rules, including those incorporated into the Sarbanes-Oxley Act, Dodd-Frank Act, the IRS Qui Tam whistleblower amendments, and Whistleblower Protection Enhancement Act. He is the author of the first legal treatise on whistleblowing and is the world’s most published author on whistleblower protection. His most recent book is The New Whistleblower’s Handbook: A Step-by-Step Guide to Doing What’s Right and Protecting Yourself. In 1988 he helped found the National Whistleblower Center, where is currently serves, pro bono, as Chairman of the Board. Steve Kohn also teaches an annual seminar on Whistleblower Law at the Northeastern University School of Law.

Our Client Received the Largest Whistleblower Reward in World History of $104 Million

Bradley Birkenfeld broke the back of Swiss bank secrecy. He was the first Swiss banker to file a case under the IRS whistleblower law. The results were unprecedented. UBS bank (at the time the largest bank in the world) had to pay a fine of $780 million. They also had to close all known U.S. accounts, and for the first time in history, the bank turned over the names of 4450 U.S. taxpayers for prosecution in the United States. Mr. Birkenfeld obtained the largest ever individual qui tam whistleblower award in history, $104 million.
