Promoting International Qui Tam Whistleblowing

He has given major keynote addresses in Peru and Greece and presented in numerous international conferences and has testified on behalf of whistleblowers before the European Parliament and the Danish Parliament.

And play an instrumental role in drafting whistleblower protection laws, such as the Sarbanes-Oxley Act (SOX), The Whistleblower Protection Enhancement Act, and the Dodd-Frank Act.
SEC & IRS Rulemaking
During the Dodd-Frank rulemaking process, our partners worked closely with the SEC to create an effective whistleblower program. Kohn, Kohn & Colapinto’s partners met personally with each of the five SEC Commissioners. They presented them with detailed reports and proposals setting forth rules that were essential to make the law work for Dodd-Frank whistleblowers as intended by Congress. Furthermore, Kohn, Kohn & Colapinto’s whistleblower attorneys seek to protect and enhance legal protections for tax fraud whistleblowers.
