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.”

What Makes a Whistleblower Law Successful In Today’s Globalized World? Part V
Originally posted in Mondaq Specific considerations for European States implementing the EU Directive On October 23, 2019, the European Union passed a Directive designed to protect citizens who report violations of law, i.e., whistleblowers. Pursuant to this mandate, twenty-seven countries must now adopt individual whistleblower protection laws fulfilling the Directive's requirements by December 17, 2021. Therefore, right now, and throughout the remainder of 2020, each EU nation is debating the contents of a domestic whistleblower law that, at a minimum, implements the Directive. In order to provide guidance on how such national legislation should look, Part V of this series focuses on the most important special considerations for EU nations in this process, in order to ensure that these laws both successfully implement the framework provided by the Directive and sufficiently encourage and protect whistleblowers. Article 6 (Anonymous Reporting) Under Article 6 of the EU Directive, Member States have the discretion ...
The International State of Corruption: Why the Foreign Corrupt Practices Act Continues to be the Most Successful Mechanism Available to Fight Corruption
Originally posted in The National Law Review Corruption has severe damaging effects on democratic institutions, undermining public accountability and diverting public resources from important priorities such as health, education, and infrastructure. As stated by former Secretary-General of the United Nations, Kofi Annan, on the passage of the United Nations Convention Against Corruption: Corruption is an insidious plague that has a wide range of corrosive effects on societies. It undermines democracy and the rule of law, leads to violations of human rights, distorts markets, erodes the quality of life and allows organized crime, terrorism and other threats to human security to flourish. Essentially, if left unchecked, corruption becomes more than just an economic or international development issue, it begins to threaten basic human rights. One of the primary ways corruption manifests is through bribery and improper uses of official funds. And despite the damage such crimes cause to global development, there ...
What Makes A Whistleblower Law Successful In Today’s Globalized World? Part IV
Originally published in Mondaq In order to be truly successful at preventing fraud, whistleblower protections must cover disclosures permitted under international anti-corruption conventions and encourage whistleblowers to cooperate with foreign governments' law enforcement agencies as permitted by these conventions. Explicitly permitting certain whistleblowers to cooperate with such law enforcement agencies without being subject to retaliation in their home countries is important for several reasons. First, corruption (particularly bribery and fraud) and dangers to public health and the environment are often transnational in nature. For example, the current COVID-19 pandemic is worldwide, and whistleblowers from China providing information as to the nature and severity of the virus would have been instrumental combating its spread. Additionally, pollution and other environmental problems are inherently incapable of adhering to national boundaries. Moreover, as clearly illustrated by Foreign Corrupt Practices Act (a U.S. law prohibiting amongst other things, the bribery of foreign officials) cases, ...
