Summary: written with AI from the case record.

What it's about
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.
The case clarifies how False Claims Act filing deadlines work when a private whistleblower brings a suit and the government declines to join.
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).
What the Court decided
Holding
The limitations period in §3731(b)(2) applies in a relatorinitiated suit in which the Government has declined to intervene. Both Government-initiated suits under §3730(a) and relator-initiated suits under §3730(b) are “civil action[s] under section 3730.” Thus, the plain text of the statute makes the two limitations periods applicable in both types of suits. Cochise claims that starting a limitations period when the party entitled to bring a claim learns the relevant facts is a default rule of tolling provisions, so subsection (b)(2) should apply only when the Government is a party.
