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.
