Who Can File a False Claims Act Whistleblower Lawsuit: What You Know Matters More Than Your Job Title

A private individual or organization with information about fraud involving federal money may file a False Claims Act lawsuit. You may know the work that was actually done, the diagnosis someone added or the instruction that changed a claim. You may have left the company, worked for a contractor or recognized the problem from outside the business. We start with what you know and how you learned it, then connect that account to the government’s payment or the money it was owed.

The False Claims Act allows a private person to bring a case in the government’s name. That is a qui tam lawsuit, and the whistleblower bringing it is called the relator. The injury at the center of the case is the government’s: taxpayers paid on a false account, or money owed to the government was improperly kept.

Must I Be an Employee?

No. False Claims Act whistleblowers include employees and former employees, but the role extends beyond the defendant’s payroll. A contractor’s knowledge of the work, a specialist’s understanding of a payment system or a competing business’s knowledge of the product can supply a different view of the same conduct.

We look at your relationship to the business alongside the information you can explain.

Employees and Former Employees

An employee may see a billing instruction, an altered record or the response to an internal audit. A former employee may be able to explain the same decisions from the work they did before leaving. The questions concern what happened inside the business and who knew about it.

A former employee brought the case against Duke University over alleged research fraud. The whistleblower alleged that fabricated research supported federal grant applications and progress reports. Duke agreed to a $112.5 million civil settlement.

Contractors, Specialists and Competitors

Work outside the defendant’s payroll can still put someone close to the transaction. Contract analysis, technical knowledge and an understanding of what was delivered can help explain the difference between the work and the account presented for payment.

The whistleblower in the Toyo Ink case was the president of a competing domestic producer. The government alleged that pigment made in China and India received finishing work in Japan and Mexico, then was declared as originating in those latter countries without the manufacturing change needed to support that claim. Toyo Ink agreed to a $45 million settlement. The federal money was customs duty the government alleged was owed, and the whistleblower came from a rival business.

For a competitor, product knowledge can be the starting point. We examine how that knowledge connects to what the business told the government and the payment advantage it allegedly obtained.

Organizations and Data Analysts

Organizations and people working with public data also bring qui tam cases. In its April 2026 FOCUS announcement, the Department of Justice attributed much of the recent increase in filings to people or companies analyzing public government data.

For an analyst, we want to understand the transactions behind the pattern and how the analysis connects them to the alleged fraud. Questions about public disclosure and the source of the information belong in that conversation with us. We assess the analysis and the potential filer’s role together.

What Your Position Lets You See

Useful information connects the conduct, the record carrying it and the government’s money. You might know who directed a change, what the original record said or why an internal finding contradicted the version used for payment. You can talk with us about that part of the story before you know how every department fits into it.

Health Care Staff Can See How a Diagnosis Becomes a Code

A healthcare whistleblower may understand how a clinical record became a billing input. The handoff between staff can reveal the decision that changed what the government was told.

In a whistleblower complaint concerning Kaiser, the allegation followed a Medicare Advantage malnutrition diagnosis from a dietician’s stamp through a physician’s signature to the coder:

United States ex rel. Stein v. Kaiser Foundation Health Plan, whistleblower complaint, paragraph 72

The allegation put the basis for the code inside an ordinary workflow: a stamp, a countersignature and a coding decision. Someone who understood that handoff could explain where the diagnosis came from without being the person who sent the final submission.

Contract Workers Can See What a Timecard Leaves Out

A contract worker may know whether the hours recorded match the work performed. The instruction to change a timecard can explain how the government’s bill acquired its false input.

In a whistleblower complaint concerning Halliburton and KBR, the whistleblower alleged that employees whose timecards differed from management’s required weekly total were called over the site radio to change them. The complaint also alleged that management changed custody of the timesheets before a government audit, requiring employees to leave them with management and sign daily entries in managers’ presence.

We would want to understand the work, the original entry and the instruction that changed it. In the alleged scheme, management’s desired total drove the timecard. Backwards.

The Payment Can Pass Through Another Business

The government-payment connection can run through a contractor or grant recipient. A false bill to a contractor or grant recipient can fall under the False Claims Act when the money serves a federal program and the government supplies or reimburses some of it.

That matters to someone working a step away from the agency paying the bill. We trace the contract, grant or program behind the transaction with you. We also examine money the business owed the government, including duties or retained overpayments, where the alleged fraud concerns keeping money rather than obtaining a new payment.

The Government Is Part of the Case

A private whistleblower starts the qui tam case for the United States, and the government decides whether to take it over. If it does, it leads the case and the whistleblower stays involved. If it declines, the whistleblower may continue the case.

The Congressional Research Service’s 2009 report, Qui Tam: The False Claims Act and Related Federal Statutes, explains this shared arrangement: a private party can start enforcement while the government retains authority over its claim. Your knowledge supplies an account the government can investigate, including the decisions behind the transaction.

The Duke case illustrates why the government’s decision to join is a separate question. The government did not take over that whistleblower’s case, which nevertheless produced the settlement described above.

When Your Role Needs a Closer Look

We work through questions about your role with you and False Claims Act whistleblower lawyers who understand the program involved.

If you helped carry out the conduct, tell us what you were asked to do and what you understood at the time. We address your participation with you.

We identify the government program and funding behind your account so the team assessing your case starts with the right questions.

What Share Is Possible?

A whistleblower case under the False Claims Act can pay 15% to 30% of what the government recovers. The reward comes from the money recovered on the claims in your case. The connection between your information and those claims matters to the case we build with you.
