Federal Judges Challenge Constitutional Basis of False Claims Act Whistleblower Provisions

Federal courts are increasingly questioning the constitutionality of the False Claims Act’s qui tam provisions, potentially threatening one of the government’s most powerful fraud-fighting tools. Recent rulings from judges in Florida and Texas suggest a growing judicial movement that could fundamentally reshape how fraud against the government is prosecuted.

In a landmark decision on October 1, 2024, U.S. District Judge Kathryn Mizelle of the Middle District of Florida ruled in United States ex rel. Zafirov v. Florida Medical Associates that the FCA’s qui tam mechanism violates the Constitution’s Appointments Clause. Judge Mizelle concluded that the law improperly allows private individuals to exercise executive power by litigating on behalf of the United States without being properly appointed under Article II.

The ruling represents a dramatic departure from decades of judicial precedent upholding the FCA’s whistleblower provisions, which permit private citizens, known as relators, to file lawsuits on the government’s behalf against entities that submit false claims for payment. Successful whistleblowers can receive up to 30% of any recovery.

Echoing these constitutional concerns, Judge James C. Ho of the Fifth Circuit Court of Appeals recently authored a concurring opinion in United States ex. rel. Gentry v. Encompass Health Rehab. Hosp. of Pearland, urging a reconsideration of “serious constitutional problems” with the qui tam structure. While agreeing with the court’s decision to dismiss the case on other grounds, Judge Ho specifically called on the Fifth Circuit to revisit its 2001 ruling in Riley v. St. Luke’s Episcopal Hospital that had previously affirmed the constitutionality of the FCA’s qui tam provisions.

“These recent opinions reflect a growing trend of judicial skepticism toward the FCA’s whistleblower mechanism,” said Michael Granston, former director of the Department of Justice’s Civil Fraud Section. “We’re seeing momentum building among conservative judges to fundamentally reconsider the constitutional foundation of qui tam actions.”

The judicial challenges come at a time when the Supreme Court has already shown interest in examining the FCA’s structure. In last year’s United States ex rel. Polansky v. Executive Health Resources, Inc. decision, Justice Clarence Thomas explicitly questioned the constitutionality of qui tam provisions in a dissenting opinion, while Justices Brett Kavanaugh and Amy Coney Barrett expressed similar concerns in a concurrence.

The Justice Department has appealed Judge Mizelle’s ruling to the Eleventh Circuit, where briefing is currently underway. If the Eleventh Circuit affirms Mizelle’s reasoning, it would create a circuit split with other federal appeals courts that have previously upheld the FCA’s constitutionality, potentially forcing the Supreme Court to resolve the issue.

Healthcare and defense industries are watching these developments with particular interest. Since the FCA’s modernization in 1986, the law has been the government’s primary tool for combating fraud in Medicare, Medicaid, and defense contracting, recovering over $72 billion. Significantly, whistleblower-initiated cases account for approximately 80% of all FCA recoveries.

“The implications for government contractors and healthcare providers are enormous,” explained Jennifer Arlen, professor at NYU School of Law. “If courts ultimately determine that qui tam provisions are unconstitutional, it would dramatically reduce the government’s ability to detect and prosecute fraud, as federal agencies lack the resources to identify most fraudulent schemes without whistleblower assistance.”

For now, the rulings apply only to the parties directly involved and, more broadly, to FCA cases where the government has not intervened. However, defendants facing qui tam lawsuits may increasingly raise constitutional challenges based on these recent decisions.

The FCA’s supporters argue that the law’s historical roots—dating back to the Civil War when President Lincoln sought to combat contractor fraud—and its long acceptance by courts should preserve its constitutionality. Critics counter that modern separation-of-powers doctrine demands stricter adherence to Article II’s appointment requirements for those exercising government authority.

As these cases progress through the federal judiciary, both whistleblowers and potential FCA defendants should closely monitor developments that could fundamentally reshape one of America’s oldest and most consequential anti-fraud statutes.
