The public disclosure bar

The False Claims Act can bar relators from proceeding if the fraud allegations are based on publicly disclosed information — such as news reports, government audits, or certain other proceedings — unless an exception applies.

2

The two statutory routes for an original source

Section 3730(e)(4)(B) describes two routes. One concerns a person who voluntarily disclosed the relevant information to the government before the public disclosure.

The other concerns independent knowledge that materially adds to the publicly disclosed allegations or transactions, coupled with voluntarily providing that information to the government before filing. Being an employee, or repeating a public report, does not by itself resolve the test.

3

Why insiders matter

Employees with firsthand documents, emails, billing data, or witness knowledge of how a scheme operated are more likely to survive public disclosure challenges than those repeating already-public allegations.

4

Work with counsel early

Public disclosure and first-to-file issues are among the earliest motions defendants file. Experienced qui tam attorneys evaluate these bars before filing. This article is general information, not legal advice.

Key takeaways

  • Public disclosure and original-source status are separate parts of the statutory test.
  • Independent knowledge must materially add to public allegations under one statutory route.
  • That route also requires voluntary disclosure to the government before filing.
