The Public Disclosure Bar and the Original Source Exception
The statute will not pay a relator for repeating what the public already knew. It also will not let that principle swallow cases built by people who found the fraud themselves, so it defines an exception in two parts that operate on completely different timelines.

The rule in short
Section 3730(e)(4) requires dismissal, unless the government opposes it, where substantially the same allegations or transactions were publicly disclosed through one of three channels: a federal hearing in which the government is a party, a federal report or audit, or the news media. A relator survives as an original source either by voluntarily disclosing the information to the government before that public disclosure, or by holding independent knowledge that materially adds to it.
The False Claims Act pays for information, not for reading. Section 3730(e)(4) directs a court to dismiss an action if substantially the same allegations or transactions were already publicly disclosed, unless the government opposes dismissal or the relator is an original source. The provision generates more motions than any other part of the statute, and most of them turn on two questions: was there a qualifying disclosure, and did it say substantially the same thing.
The three channels of disclosure
Not every public statement counts. The provision lists three channels, and a disclosure outside them does not trigger the bar no matter how widely known the information is. The first is a federal criminal, civil or administrative hearing in which the government or its agent is a party. The second is a congressional, Government Accountability Office, or other federal report, hearing, audit or investigation. The third is the news media.
Two limits in that list are easy to miss. The hearing channel requires the government or its agent to be a party, so private civil litigation between two companies does not qualify even when the pleadings describe the fraud precisely. The report channel is federal only, so a state auditor's findings are outside it. The news media channel carries no such limitation and is the broadest of the three.
What counts as a federal report
The Supreme Court read the report channel broadly in Schindler Elevator. A federal agency's written response to a Freedom of Information Act request, including the records produced with it, is a report within the ordinary meaning of the word. The Court declined to narrow the term to formal published documents, and the practical consequence is significant: a relator who builds a case by filing information requests may be building the very disclosure that bars him.
Agency inspector general reports, audit findings, and administrative investigation files all fall comfortably within the channel. What matters is that the disclosure be public. Material provided to the government but not released, and material shared inside an agency, are not public disclosures merely because the government possesses them.
The substantially the same standard
The comparison is between the disclosed material and the relator's allegations or transactions. Courts commonly ask whether the public record contained enough to set the government on the trail of the fraud, either by stating the allegation outright or by disclosing both the misrepresented state of facts and the true state of facts, from which the inference of fraud follows.
That formulation explains most outcomes. A public report showing that a contractor billed for a service, without anything indicating the service was not performed, discloses only half the equation and does not bar the case. A report showing both the billing and the non-performance discloses the fraud even if nobody drew the conclusion in print.
Two further points recur in the motions. The disclosure need not name the defendant if it describes an industry practice specifically enough that the government could identify the participants, though courts differ on how specific that must be. And the comparison is made claim by claim, so a relator may lose part of a complaint and keep the rest. Defendants therefore attach the public material to the motion and match it against the pleading paragraph by paragraph, which is why the disclosure fight is usually resolved on documents rather than testimony.
The first route requires the relator to have gone to the government before the public disclosure happened. It cannot be satisfied retroactively, and a relator who learns of a disclosure and then reports is out of that route permanently. The second route allows disclosure after the public one, but it must come before filing the action and the knowledge must materially add to what was already out. Serving the disclosure statement at the moment of filing has been held insufficient in some courts, which is a needless risk.
The two routes to original source status
Section 3730(e)(4)(B) defines an original source in the alternative. The first branch covers a person who, prior to a public disclosure, voluntarily disclosed to the government the information on which the allegations or transactions in a claim are based. The second covers a person who has knowledge that is independent of and materially adds to the publicly disclosed allegations or transactions, and who has voluntarily provided the information to the government before filing.
| Requirement | First route | Second route |
|---|---|---|
| Timing of disclosure to the government | Before the public disclosure occurred | Before the action is filed |
| Relationship to the public material | Irrelevant; the relator was there first | Must be independent of it and materially add to it |
| Voluntariness | Required | Required |
| What usually defeats it | Reporting only after reading the disclosure | Adding detail that is merely cumulative |
| Typical proof | Dated correspondence with an agency or hotline record | Internal documents and firsthand observation |
The government's power to defeat the bar
The current text opens with a conditional: the court shall dismiss unless opposed by the Government. That clause gives the United States a veto over the bar. Where the government believes a case is worth pursuing despite an earlier disclosure, it can file a statement opposing dismissal and the motion fails on that ground alone.
The veto is used sparingly and cannot be relied on. It is most likely where the relator brought real value, where the disclosure was technical rather than substantive, or where the government has already invested in the investigation. Relators facing the bar therefore argue original source status as the primary position and treat government opposition as a fortunate second line.
Because the bar is decided early, it interacts with the other threshold defenses. A defendant will ordinarily raise it alongside the first-to-file bar and any pleading challenge to the falsity theory described in express and implied certification. Where the disclosure question depends on documents outside the complaint, courts resolve it using the ordinary tools discussed in judicial notice, burdens and presumptions, and a relator who preserved dated proof of his own reporting during the sealed filing process is in a far stronger position on the record than one relying on recollection.
Points to carry away
- The bar applies only where the disclosure came through one of three statutory channels.
- The test is whether substantially the same allegations or transactions were disclosed, not whether the relator read them.
- A response to a Freedom of Information Act request is a report for this purpose, as the Supreme Court held in Schindler.
- The government can defeat the bar by opposing dismissal.
- One route to original source status requires disclosure to the government before the public disclosure occurred.
- The other requires independent knowledge that materially adds to what was public, provided to the government before filing.
Questions readers ask
Does it matter that the relator never saw the public disclosure?
Not to the bar itself. The provision asks whether substantially the same allegations or transactions were publicly disclosed, not whether the relator derived anything from them. A relator who independently uncovered a scheme can still be barred because a federal audit described it years earlier. That result is what makes original source status so important, since the second route is designed for exactly this position: genuine independent knowledge that adds materially to what was already available to the public.
Is a state court filing a public disclosure?
Under the current text, generally no. The hearing channel is limited to a federal criminal, civil or administrative hearing in which the government or its agent is a party, and the report channel is limited to congressional, Government Accountability Office or other federal sources. State proceedings and state reports fall outside those descriptions. They can still cause practical trouble, because material filed in a state case often gets picked up by the news media, and the news media channel has no federal limitation at all.
How much extra information counts as materially adding?
Enough to make a real difference to the government's ability to investigate. Courts have said the addition must be substantive rather than merely cumulative, and that filling in details of a scheme already described in outline may not be enough. What tends to satisfy the standard is information that changes the picture: naming the participants where the disclosure was anonymous, showing that conduct described as isolated was systematic, or supplying the internal documents proving knowledge. Volume alone does not help.

Filing a Qui Tam Complaint Under Seal
Under 31 U.S.C. 3730(b) a private relator may sue in the name of the United States. The complaint is filed in camera, remains under seal for at least sixty days, and is not served on the defendant until the court orders it. A copy of the complaint and a written disclosure of substantially all material evidence and information the relator possesses must be served on the government. The United States is the real party in interest throughout.
Employment Agreements That Try to Bar Whistleblowing
Rule 21F-17 provides that no person may take any action to impede an individual from communicating directly with Commission staff about a possible securities law violation, including by enforcing or threatening to enforce a confidentiality agreement. The commodities rules contain a parallel prohibition. Section 3730(h) separately entitles an employee, contractor or agent who suffers retaliation to reinstatement, double back pay with interest and special damages.
The Seal Period, Extensions and What May Not Be Said
Section 3730(b)(3) allows the government to move for extensions of the sixty-day seal for good cause, and those motions are made in camera. The seal binds the relator as well as the government: the existence of the action, its contents and the identity of the defendant are not to be disclosed. Breaking the seal does not automatically end the case, and courts weigh the harm to the government, the severity of the violation and evidence of bad faith.
