How a Federal False Claims Act Case Works: Qui Tam, the Elements, and the Bars That End Cases Early

Most False Claims Act cases do not start with the government. They start with a private person, called a relator, who files suit in the government's name and under seal. The case then moves through a set sequence: a sealed investigation, a government decision whether to take over, and litigation if it proceeds. If your company has received a document subpoena in a sealed matter, learned that a former employee filed a complaint, or been named in an unsealed qui tam suit, the sequence explains what has already happened and what comes next. This guide walks through the process, and it also lays out what the government or a relator actually has to prove, because in the Eleventh Circuit those elements are well defined and several of them end cases before the merits. It is an evergreen explainer, not an update on any particular case.

A note on authority. The elements and standards below come primarily from Eleventh Circuit decisions, which bind federal courts in Florida, Georgia, and Alabama, layered over a few Supreme Court holdings that control everywhere. A rule from another circuit is persuasive here, not binding.

The statute and the two ways it is enforced

The False Claims Act, 31 U.S.C. §§ 3729 through 3733, imposes civil liability on anyone who knowingly presents a false or fraudulent claim for federal payment, or knowingly uses a false record material to such a claim. 31 U.S.C. § 3729(a)(1)(A)-(B). Liability is severe. Each violation carries treble damages plus a penalty for every individual false claim, so the totals can far exceed the government's actual loss.

The statute can be enforced two ways. The Attorney General can sue directly. Or a private person can sue "for the person and for the United States Government," in the government's name, through the qui tam provisions. 31 U.S.C. § 3730(a), (b). Private enforcement is how most cases begin, and it carries its own mechanics a defendant needs to understand.

What the claim actually requires: presentment

One principle organizes the whole statute in the Eleventh Circuit. Liability attaches to the claim, not to the underlying misconduct. In United States ex rel. Clausen v. Laboratory Corp. of America, 290 F.3d 1301 (11th Cir. 2002), the court held that without the presentment of a false claim to the government, "there is simply no actionable damage to the public fisc," and that the submission of a claim is "the sine qua non of a False Claims Act violation." Clausen, 290 F.3d at 1311. The statute does not create liability for a provider's disregard of regulations or sloppy internal procedures unless, as a result, the provider knowingly asks the government to pay money it does not owe. Clausen, 290 F.3d at 1311.

The Eleventh Circuit has held the line. In Olhausen v. Arriva Medical, LLC, 124 F.4th 851 (11th Cir. 2024), the court held that the false-record provision, § 3729(a)(1)(B), like the presentment provision, § 3729(a)(1)(A), includes a presentment requirement. The plaintiff must show that false or fraudulent claims were actually presented to the government for payment. Olhausen, 124 F.4th at 862-64. A relator cannot skip presentment by recasting the theory as a false-record claim. This is the newest word from the Circuit on the point, and it favors defendants.

The elements of a false-certification claim

Many health care False Claims Act cases proceed on a false-certification theory. On that theory, the defendant certified compliance with a law or regulation, the certification was false, and the government paid. The Eleventh Circuit has expressly adopted this theory and set out its elements. In Urquilla-Diaz v. Kaplan University, 780 F.3d 1039 (11th Cir. 2015), the court held that a relator must prove "(1) a false statement or fraudulent course of conduct, (2) made with scienter, (3) that was material, causing (4) the government to pay out money or forfeit moneys due." Urquilla-Diaz, 780 F.3d at 1045. The court reaffirmed that same four-element test in Ruckh v. Salus Rehabilitation, LLC, 963 F.3d 1089 (11th Cir. 2020). Ruckh, 963 F.3d at 1103. A defendant evaluating a certification theory should test each of the four elements separately, because a weakness in any one of them can be dispositive.

Scienter. The knowledge element is defined by statute and is narrower than it first looks. Under § 3729(b), "knowingly" means actual knowledge, deliberate ignorance, or reckless disregard, and proof of a specific intent to defraud is not required. Urquilla-Diaz, 780 F.3d at 1058. The Eleventh Circuit has explained that reckless disregard reaches gross negligence, the head-in-the-sand defendant, but not honest mistakes or ordinary negligence. Urquilla-Diaz, 780 F.3d at 1058. The Supreme Court has since made the inquiry subjective. In United States ex rel. Schutte v. SuperValu Inc., 598 U.S. 739 (2023), the Court held that scienter turns on what the defendant actually knew and believed, not on what an objectively reasonable person might have believed. Schutte, 598 U.S. at 740-41.

Materiality. The Supreme Court has set a high bar. In Universal Health Services, Inc. v. United States ex rel. Escobar, 579 U.S. 176 (2016), the Court held that "[t]he materiality standard is demanding." Escobar, 579 U.S. at 194. A requirement is not material merely because the government called compliance a condition of payment, and where the government "pays a particular claim in full despite its actual knowledge that certain requirements were violated, that is very strong evidence that those requirements are not material." Escobar, 579 U.S. at 195. The Eleventh Circuit applied that standard in Ruckh. A defendant who can show the government kept paying with knowledge of the alleged violation has one of the strongest defenses the statute allows.

The pleading standard: Rule 9(b)

A False Claims Act complaint pleads fraud, so it must satisfy the heightened particularity standard of Federal Rule of Civil Procedure 9(b), and many complaints fail there. In Clausen, the court held that a relator must give "some indicia of reliability" that an actual false claim was submitted, and that a plaintiff who cannot identify a single claim by amount, date, or number does not get a ticket to discovery. Clausen, 290 F.3d at 1311. The Eleventh Circuit has framed the requirement as the familiar "who, what, when, where, and how" of the alleged fraud. Urquilla-Diaz, 780 F.3d at 1052. A complaint that describes a fraudulent scheme in general terms, without connecting it to claims actually presented, is vulnerable at the threshold.

The life of a qui tam case

The sealed filing. The relator files the complaint under seal and serves it, with the supporting evidence, on the government alone, not on the defendant. The complaint stays sealed at least 60 days while the government investigates. 31 U.S.C. § 3730(b)(2). In practice the seal is often extended, sometimes for years, and a defendant may first learn of a sealed matter through a subpoena or a civil investigative demand rather than the complaint.

The government's investigation. During the seal, the government evaluates the allegations, often through document demands and interviews. This is when a company may receive a civil investigative demand, and it is a critical window, because the government's view of the case is still forming.

The intervention decision. At the end of the seal, the government decides whether to intervene and take the lead, or to decline and let the relator proceed alone. 31 U.S.C. § 3730(b)(4). The government intervenes in a minority of cases. Intervention signals how the government reads the case, though a declined case can still proceed and settle.

The government's continuing dismissal power. Even after declining, the government may later intervene and move to dismiss over the relator's objection. In United States ex rel. Polansky v. Executive Health Resources, Inc., 599 U.S. 419 (2023), the Supreme Court held that a court reviews such a motion under the ordinary voluntary-dismissal standard of Federal Rule of Civil Procedure 41(a), and should grant it in all but the most exceptional cases. Polansky, 599 U.S. at 422. For a defendant facing a weak declined case, persuading the government to use that power is a real, if deferential, avenue.

Litigation and resolution. If the case proceeds, it moves like any other civil fraud suit, through pleadings, motions, discovery, and either settlement or judgment. A successful relator recovers between 15 and 30 percent of the proceeds, depending on whether the government intervened and on the relator's contribution. 31 U.S.C. § 3730(d). Most cases resolve by settlement, without an admission of liability.

The threshold bars that end cases early

Several provisions can end a qui tam case before the merits, and they are among the first things a defendant's counsel evaluates.

• The first-to-file bar blocks a later relator from suing on the same underlying facts as an earlier pending action. 31 U.S.C. § 3730(b)(5).
• The public-disclosure bar defeats claims already aired publicly, unless the relator is an "original source." 31 U.S.C. § 3730(e)(4). The Eleventh Circuit applies a three-part inquiry: whether the allegations were publicly disclosed; if so, whether the disclosed information is the basis of the suit; and if so, whether the relator is an original source of that information. United States ex rel. Saldivar v. Fresenius Medical Care Holdings, Inc., 841 F.3d 927, 933 (11th Cir. 2016). An original source is one with "direct and independent knowledge" who "voluntarily provided the information to the Government before filing." Saldivar, 841 F.3d at 932-33.
• How the public-disclosure bar is raised changed in 2010. In United States ex rel. Osheroff v. Humana, Inc., 776 F.3d 805 (11th Cir. 2015), the court held that the post-2010 version of § 3730(e)(4) "creates grounds for dismissal for failure to state a claim rather than for lack of jurisdiction." Osheroff, 776 F.3d at 811. The bar is now an affirmative defense raised under Rule 12(b)(6), which affects how and when it is litigated.
• The pleading standard, Rule 9(b), as discussed above, ends many complaints at the threshold.

None of these reaches whether the conduct was actually fraudulent. They are gatekeeping rules, and they dispose of a meaningful share of cases without the court ever weighing the merits.

A short glossary

• Qui tam: a suit brought by a private person on the government's behalf under the False Claims Act.
• Relator: the private person who brings a qui tam suit, sometimes called a whistleblower.
• Seal: the period during which the complaint is confidential and served only on the government.
• Presentment: the requirement that a false or fraudulent claim actually be submitted to the government, the "sine qua non" of liability under Clausen.
• Intervention: the government's decision to take over the lead role.
• Treble damages: three times the government's actual damages, plus per-claim penalties.
• Materiality: whether the alleged falsehood was important to the government's payment decision, a "demanding" standard under Escobar.
• First-to-file bar / public-disclosure bar: threshold rules that can defeat a later or already-public claim.
• Original source: a relator with direct and independent knowledge who can overcome the public-disclosure bar.

Questions a business reader should be ready to ask

These are prompts for a conversation with counsel, not steps to take alone.

• If we received a subpoena or civil investigative demand, is there a sealed qui tam case behind it?
• What does a preservation obligation require of us right now?
• Can the relator identify specific claims we presented, or is the complaint vulnerable under Rule 9(b)?
• Do any threshold bars apply, such as first-to-file or public disclosure?
• Did the government keep paying our claims with knowledge of the alleged problem, which bears on materiality under Escobar?
• Is this a case the government is likely to intervene in, decline, or move to dismiss?

The mechanics above are stable, but the constitutional questions surrounding qui tam are not all settled. Our separate article on the Eleventh Circuit's September 2026 decision covers the constitutional challenge to the qui tam structure, including which theories a court has resolved and which remain open. This guide and that analysis answer different questions.
