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.

What Makes A Whistleblower Law Successful In Today’s Globalized World? Part III
Originally published in Mondaq Part III: Tailored free speech and evidentiary standards should be explicitly incorporated into whistleblower legislation to ensure that whistleblowers are not chilled from making vital disclosures Any state considering a new or updated whistleblower law should consider certain basic principles underlying successful anti-retaliation laws, namely, whistleblower protection laws should adequately address the threat of retaliatory lawsuits and legal tactics and prohibit restrictive non-disclosure agreements that prevent or "chill" employee disclosures of violations of law. In enacting whistleblower laws, many states make the mistake of simply applying existing laws on free speech and ignoring the impact that retaliatory lawsuits, such as libel suits, have on whistleblowers. In order to make sure that whistleblowers are not chilled from making disclosures of violations of law and threats to public safety, tailored laws are essential for any whistleblower program to be successful. First, nations considering enacting or modifying whistleblower laws ...
What Makes A Whistleblower Law Successful In Today’s Globalized World? Part II
Originally posted in Mondaq Reward programs for whistleblowers are in nations' best interests and serve as a form of anti-retaliation insurance for whistleblowers. As explored in Part I of this series, whistleblower laws around the world are nonexistent or largely inadequate and focus primarily on post-retaliation remedies, which often cannot truly make a whistleblower whole and often raise the specter of prolonged and costly litigation against a very powerful and well-financed employer. This in turn has a chilling effect on the willingness of employees to report fraud and take advantage of anti-retaliation laws. To overcome these barriers to whistleblowing, following the overwhelming success of the U.S. Securities & Exchange Commission's whistleblower reward program, nations creating new whistleblower laws should begin by implementing an award provision for successful whistleblower tips (as recently implemented by Lithuania). An effective provision might read: If the whistleblower's original information is the proximate cause of ...
Rights Groups File Complaint Against ICE, Giving Credence to Whistleblower Allegations of Forced Hysterectomies
Project South, Georgia Detention Watch, Georgia Latino Alliance for Human Rights, South Georgia Immigrant Support Network filed a complaint with ICE officials condemning the inhumane conditions at the private Irwin County Detention Center in Georgia. This complaint is based, in large part, on the allegations of nurse-turned-whistleblower, Dawn Wooten. Amongst the shocking allegations is that detained women, who often don’t speak English, were receiving hysterectomies at an extremely high rate without informed consent or medical necessity. This harkens back to the U.S. funded forced sterilization of Black, Puerto Rican, Chicano, and Native American women until the 1970s, as well as the concentration camps of Nazi Germany. Therefore, these allegations are not as outrageous as they may seem and must be investigated with the utmost urgency. Ms. Wooten is incredibly brave for collecting information on the violations and reporting them to rights groups. Ms. Wooten’s report is particularly important because it ...
