- What it's about
This case asked how the False Claims Act’s statute of limitations applies when a private whistleblower brings a qui tam suit and the United States chooses not to intervene. The Court held that the whistleblower may rely on the Act’s 3-year knowledge-based limitations period in that situation, but the whistleblower is not the "official of the United States" whose knowledge starts that period.
Question presented
The question presented is whether a relator in a False Claims Act qui tam action may rely on the statute of limitations in 31 U.S.C. § 3731(b)(2) in a suit in which the United States has declined to intervene and, if so, whether the relator constitutes an "official of the United States" for purposes of Section 3731(b)(2).
