Understanding Whistleblower and Qui Tam Actions
In the United States, the legal framework surrounding fraud against the government is largely anchored by the False Claims Act (FCA). This federal law is designed to protect taxpayer funds by holding individuals and corporations accountable for submitting false or fraudulent claims for payment to the government. A unique and powerful component of the FCA is the “qui tam” provision, which allows private citizens—often referred to as whistleblowers or “relators”—to file lawsuits on behalf of the United States government against entities that have defrauded federal programs.
The term “qui tam” is derived from a Latin phrase meaning “who sues in this matter for the king as well as for himself.” In modern practice, this means that a whistleblower acts as a private attorney general. By bringing evidence of fraud to light, the relator initiates a civil action that can lead to the recovery of significant government funds. Because these cases involve complex allegations of fraud, the law requires that a relator be represented by an attorney to navigate the procedural requirements of the court system.
The Process of Filing a Qui Tam Lawsuit
Initiating a qui tam action is a highly structured process that differs from standard civil litigation. When a whistleblower files a complaint, it is initially filed “under seal.” This means the lawsuit is kept confidential, and the defendant is not immediately notified of the action. This period of secrecy allows the Department of Justice (DOJ) and relevant federal agencies to investigate the allegations without alerting the party accused of fraud.
During this time, the relator must serve the government with a copy of the complaint and a written disclosure of all material evidence and information they possess. The government then reviews the case to determine whether it will “intervene.” If the government chooses to intervene, it takes the lead in litigating the case, though the whistleblower remains a party to the action. If the government declines to intervene, the whistleblower may still choose to proceed with the lawsuit on their own, although the government retains the right to intervene at a later stage if circumstances change.
The Role of the Whistleblower and Potential Recovery
Whistleblowers are often employees, contractors, or industry insiders who have direct and independent knowledge of fraudulent activity. Because they are exposing wrongdoing that might otherwise go undetected, the law provides a financial incentive for their participation. If a qui tam action is successful—resulting in a settlement or a judgment in favor of the government—the whistleblower is typically entitled to a percentage of the total recovery.
Under the False Claims Act, this share generally ranges between 15% and 30%, depending on factors such as whether the government intervened in the case and the extent to which the relator contributed to the prosecution of the action. These recoveries can be substantial, as the False Claims Act is a primary tool for recovering billions of dollars in taxpayer money annually. However, it is important to understand that the primary purpose of the statute is to protect the public interest and ensure that government funds are used for their intended purposes.
Government Oversight and Dismissal
While the qui tam provision empowers private citizens, the government maintains significant oversight. The Department of Justice evaluates each case to ensure it aligns with federal interests and enforcement priorities. In some instances, the government may seek to dismiss a qui tam action if it determines that the case does not support the government’s objectives or if it interferes with other ongoing investigations. The decision to intervene or dismiss is made on a case-by-case basis, reflecting the government’s role as the ultimate party on whose behalf the suit is brought.
