Hagens Berman—among the largest plaintiff-side law firms in the world—has decades of experience filing and prosecuting cases on behalf of whistleblowers in False Claims Act qui tam litigation, and has successfully represented dozens of Dodd-Frank whistleblowers with claims of securities fraud and commodities fraud under the SEC and CFTC programs, as well as IRS whistleblowers reporting tax fraud.

Hagens Berman’s litigation experience is unsurpassed. We have succeeded for our whistleblower clients where other lawyers have failed. We have unmatched global resources to fight for whistleblowers—unlike most other firms, Hagens Berman fights daily and wins against the world’s “too big to jail” corporations.

We Only Represent Whistleblowers

Our firm does not represent corporate or other business interests. We represent whistleblowers who challenge them. Our clients are located throughout the United States and around the world. Hagens Berman prosecutes cases in nearly every federal district and dozens of state courts. We litigate False Claims Act cases in courts across the country. We also handle Dodd-Frank whistleblower cases on behalf of our SEC and CFTC whistleblower clients with cases in nearly every Regional Enforcement office of the SEC and several CFTC Enforcement offices.

Cases brought under federal and state False Claims Act laws and under the Dodd-Frank whistleblower programs of the SEC and CFTC provide financial rewards to private citizens who properly report wrongdoing to the government.

Hagens Berman litigates False Claims Act cases on behalf of whistleblowers challenging health care fraud, defense contractor fraud, financial/banking fraud, procurement fraud, education fraud, and other fraud committed by entities that receive government funding or government insurance. 

We also represent dozens of Dodd-Frank whistleblowers under the SEC and CFTC programs, many of whom have been awarded for their reporting. Unlike the vast majority of whistleblower law firms, Hagens Berman has proven expertise in the area of financial fraud, with noted experts in securities and commodities and victories against large public companies and investment firms who committed financial fraud.

Our Law Firm is Different—And Our Cases Overcome the Odds

The law firm you choose can make all the difference. More than 90% of False Claims Act cases are unsuccessful. Less than 1% of SEC and CFTC whistleblower complaints result in an award—in fact, less than 3% of whistleblower complaints even cause the SEC or CFTC to even open an investigation. We build successful cases with our whistleblower clients that beat those odds.

Most defendants in high-stakes False Claims Act litigation retain large, powerful defense law firms to represent them. Hagens Berman is one of the few False Claims Act whistleblower law firms that successfully litigates cases against the largest and wealthiest defense firms every day in high-stakes litigation. Most whistleblower law firms do not. And choosing a firm with that kind of experience and talent can make the difference in your False Claims Act case.

Among many others, Hagens Berman represents the two most prominent whistleblowers under the SEC and CFTC whistleblower programs. Both of our clients brought successful, record-setting cases under the SEC and CFTC whistleblower programs. Other clients of ours are doing the same. We take a small number of cases—ones that will beat the odds and trigger enforcement investigations.
