Notable False Claims Act Whistleblower Cases

Our qui tam attorneys have represented all types of government and non-government whistleblowers who report fraud across several sectors. The partners currently represent qui tam whistleblowers from every continent on earth (except Antarctica) in pursuing whistleblower reward cases under U.S. laws.

Furthermore, our approach is unique. Our attorneys work as a team on many qui tam cases, which allows us to be more effective in winning cases. Our False Claims Act cases are filed under seal. This means they are confidential until the government decides to intervene and the court unseals the case. However, we’ve curated a list of the firm’s landmark whistleblower cases which are public, including:

  • Qui tam whistleblower Daniel Richardson, a former Senior District Business Manager for Bristol-Myers Squibb (BMS), prevailed in one of the largest qui tam cases filed against a major pharmaceutical company for “off label” marketing and illegal kickbacks.
  • False Claims Act James Connolly, who successfully used the California False Claims Act to hold the multinational financial services company HSBC accountable for overcharging the California Public Employees Retirement System in foreign currency trading.
  • False Claims Act whistleblower Dr. Aaron Westrick, who forced the recall of thousands of unsafe bulletproof vests sold to law enforcement and the U.S. military – effectively saving thousands of lives as a result.
  • False Claims Act whistleblower Shahiq Khawaja, who successfully filed a federal and state qui tam lawsuits against the Washington Metropolitan Area Transit Authority for illegally awarding a $14M contract to Metaformers Inc.
