There is a provision in the False Claims Act that allows whistleblowers to sue the wrongdoers and recoup a percentage of whatever compensation the government recovers. This is called “qui tam” and essentially means a private citizen is filing a lawsuit on behalf of the U.S. government. In any qui tam, the government can choose whether to join the lawsuit. The whistleblower may continue if the government declines. Fraud in qui tam actions means the intentional, significant theft or misuse of taxpayer money.
