Promoting International Qui Tam Whistleblowing
Kohn, Kohn and Colapinto has played an instrumental role in advancing whistleblower rights worldwide. Currently the partners represent whistleblowers from every continent on earth (except Antarctica) in pursuing whistleblower reward cases under U.S. laws.
Steve Kohn has been sponsored by the U.S. Department of State to promote whistleblowing on a world-wide scale, including special seminars and programs in the Czech Republic, Hungary, Bosnia, Serbia and Thailand. 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. Mike Kohn has made major international presentations in Poland, South Korea and Israel. The firm filed extensive comments supporting greater whistleblower protections in the now-approved European Directive on Whistleblowing.
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.
In recognition of the growing importance of whistleblower litigation, The National Law Journal named the whistleblower attorney and advocacy law firm of Kohn, Kohn & Colapinto as one of top fifty plaintiff’s law firms in the United States. The firm’s partners were officially named as among “America’s Elite Trial Lawyers.” In its September 29, 2014 article, “Elite Trial Lawyers: The 50 Leading Plaintiff’s Firms in America,” the National Law Journal named Kohn, Kohn & Colapinto as one of the firm’s “doing the most creative and most important work in the courtroom.”

The CFTC: An Increasingly Necessary Agency for Combatting International Fraud
The Commodities Exchange Act (“CEA”) essentially provides the Commodity Futures Trading Commission (“CFTC”) broad jurisdiction over trades and transactions involving swaps or contracts of sale of a commodity for future delivery. This means, in the commodity futures context, the CFTC is the analog of the Securities and Exchange Commission (“SEC”), and overall, the CEA and its promulgating rules mirror those of the SEC, including in its whistleblower program. Although few are aware of this program and even fewer understand the CEA rules when it comes to commodities, the reach of the CFTC enforcement has steadily expanded in direct correlation with changing market trends and increased commodity futures fraud. Futures contracts for commodities have been traded in the United States for the past 150 years. Federal regulation of such contracts began in the 1920s and matured in 1974 when the CFTC was created. With the shift in futures traded commodities ...
The SEC Turns Its Attention to Climate and Environmental Enforcement
Last week the U.S. Securities & Exchange Commission ("SEC") announced that it would be creating a new taskforce to focus on climate and environmental, social, and governance (“ESG”) enforcement. This focus reflects a growing trend of investors basing their decisions, at least in part, on the climate and environmental impacts of the companies and said companies’ ability to survive the increasing effects of global climate change. For this reason, the new SEC task force will focus on violations of Climate and ESG disclosure requirements, such as misrepresentations to the investing public as to a company’s sustainability efforts or environmental footprint. This policy change is important for whistleblowers to be aware of because a corporation’s misleading statements on these subjects are now likely to be treated as material by the SEC and may actually be prosecuted. Corporate insiders, i.e.,whistleblowers, are well-positioned to report to the SEC when they know that ...
The Netherlands Must Step Up Whistleblower Protections According to the OECD and Dutch Authorities
As reported by the Wall Street Journal, recently, the OECD published a report substantiating what whistleblower advocates and nonprofits concluded years ago: anticorruption efforts in the Netherlands have been stymied, in part due to an ineffective whistleblower system. Although the Netherlands has a whistleblower law in place, a 2015 study showed that it has not encouraged or protected whistleblowers. Eighty-five percent of the true whistleblowers who made reports under this law suffered some type of adverse consequence for reporting, and one-fourth deciding against making or continuing with a report. Now, the OECD has reported that still no foreign bribery cases have been detected and reported under this law in the Netherlands. The law has failed to provide real protection to whistleblowers. This is particularly concerning given the recent public retaliation against Jonathan Taylor, the British whistleblower who blew the whistle on the Dutch oil company SBM Offshore. SBM Offshore sued ...
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.
