Whistleblower attorney Stephen M. Kohn and partners of Kohn, Kohn & Colapinto regularly advise congress on crafting whistleblower laws. 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. Our firm has filed numerous internal revenue service rulemaking petitions, filed extensive briefs to the IRS and testified at IRS rulemaking hearsing to strengthen the tax whistleblower program.

Danske Bank Whistleblower Releases Slides from his EU Parliament Presentation
The full terms of Wilkinson's restrictive NDA are disclosed On November 21, 2018 Danske Bank whistleblower Howard Wilkinson testified before the European Parliament. His PowerPoint presentation has been made publicly available and is linked here: Money Laundering in the EU Banking Sector: what is failing? For the first time the full contents of the nondisclosure agreement (NDA) restrictions placed on Mr. Wilkinson as part of his severance agreement have been made public. According to statements by Danske Bank executives, these types of restrictions are common. Although difficult to confirm, we believe that Mr. Wilkinson's testimony constitutes the first time a European bank whistleblower or employee has publicly disclosed the types of contractual restrictions that hinder whistleblowing at financial institutions and often permits crimes to go undetected for years. The full contents of the restrictions placed on Mr. Wilkinson are set forth here: AGREEMENT ON TERMINATION OF EMPLOYMENT CONTRACT 28 April ...
