CERTIORARI TO THE UNITED STATES COURT OF APPEALS FOR 

THE ELEVENTH CIRCUIT 

No. 18–315. Argued March 19, 2019—Decided May 13, 2019 

The False Claims Act permits a private person, known as a relator, to 

bring a qui tam civil action “in the name of the [Federal] Government,” 31 U. S. C. §3730(b), against “any person” who “knowingly 

presents . . . a false or fraudulent claim for payment” to the Government or to certain third parties acting on the Government’s behalf, 

§§3729(a), (b)(2). The Government may choose to intervene in the action. See §§3730(b)(2), (4). Two limitations periods apply to a “civil 

action under section 3730.” §3731(b). An action must be brought 

within either 6 years after the statutory violation occurred, 

§3731(b)(1), or 3 years after the “the official of the United States 

charged with responsibility to act in the circumstances” knew or 

should have known the relevant facts, but not more than 10 years after the violation, §3731(b)(2). The period providing the later date 

serves as the limitations period. 

In November 2013, respondent Hunt filed a complaint alleging that

petitioners—two defense contractors (collectively, Cochise)—

defrauded the Government by submitting false payment claims for 

providing security services in Iraq up until early 2007. Hunt claims 

that he revealed Cochise’s allegedly fraudulent scheme during a November 30, 2010, interview with federal officials about his role in an 

unrelated contracting fraud in Iraq. The United States declined to 

intervene in the action, and Cochise moved to dismiss the complaint

as barred by the statute of limitations. Hunt countered that his complaint was timely under §3731(b)(2). In dismissing the action, the 

District Court considered three potential interpretations: that 

§3731(b)(2) does not apply to a relator-initiated action in which the 

Government elects not to intervene; that §3731(b)(2) applies in non-

intervened actions, and the limitations period begins when the relator knew or should have known the relevant facts; or that §3731(b)(2)

applies in nonintervened actions, and the limitations period begins

when the Government official responsible for acting knew or should

have known the relevant facts. The court rejected the third interpretation and found that Hunt’s complaint would be untimely under either of the first two. The Eleventh Circuit reversed and remanded, 

adopting the third interpretation. 

Held: 

1. 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. But treating a 

relator-initiated, nonintervened suit as a “civil action under section 

3730” for purposes of subsection (b)(1) but not subsection (b)(2) is at

odds with fundamental rules of statutory interpretation. Because a 

single use of a statutory phrase generally must have a fixed meaning, 

see Ratzlaf v. United States, 510 U. S. 135, 143, interpretations that

would “attribute different meanings to the same phrase” should be 

avoided, Reno v. Bossier Parish School Bd., 528 U. S. 320, 329. Here, 

the clear text of the statute controls. Cochise’s reliance on Graham 

County Soil & Water Conservation Dist. v. United States ex rel. Wilson, 545 U. S. 409, is misplaced. Nothing in Graham County supports giving the phrase “civil action under section 3730” in §3731(b)

two different meanings depending on whether the Government intervenes. While the Graham County Court sought “a construction that 

avoids . . . counterintuitive results,” there the text “admit[ted] of two 

plausible interpretations.” Id., at 421, 419, n. 2. Here, Cochise 

points to no other plausible interpretation of the text, so the “ ‘judicial

inquiry is complete.’ ” Barnhart v. Sigmon Coal Co., 534 U. S. 438, 

462. Pp. 4–8.

2. The relator in a nonintervened suit is not “the official of the 

United States” whose knowledge triggers §3731(b)(2)’s 3-year limitations period. The statute provides no support for such a reading.

First, a private relator is neither appointed as an officer of the United 

States nor employed by the United States. Second, the provision authorizing qui tam suits is entitled “Actions by Private Persons.” 

§3730(b). Third, the statute refers to “the” official “charged with responsibility to act in the circumstances.” Regardless of precisely

Syllabus 

which official or officials the statute is referring to, §3731(b)(2)’s use

of the definite article “the” suggests that Congress did not intend for 

private relators to be considered “the official of the United States.” 

See Rumsfeld v. Padilla, 542 U. S. 426, 434. Nor are private relators 

“charged with responsibility to act” in the sense contemplated by

§3731(b), as they are not required to investigate or prosecute a False 

Claims Act action. Pp. 8–9. 

887 F. 3d 1081, affirmed.

No. 18–315 

COCHISE CONSULTANCY, INC., ET AL., PETITIONERS 

v. UNITED STATES, EX REL. BILLY JOE HUNT 

ON WRIT OF CERTIORARI TO THE UNITED STATES COURT OF 

APPEALS FOR THE ELEVENTH CIRCUIT 

[May 13, 2019] 

JUSTICE THOMAS delivered the opinion of the Court. 

The False Claims Act contains two limitations periods 

that apply to a “civil action under section 3730”—that is, 

an action asserting that a person presented false claims to

the United States Government. 31 U. S. C. §3731(b). The 

first period requires that the action be brought within 6

years after the statutory violation occurred. The second 

period requires that the action be brought within 3 years

after the United States official charged with the responsibility to act knew or should have known the relevant facts, 

but not more than 10 years after the violation. Whichever 

period provides the later date serves as the limitations 

period.

This case requires us to decide how to calculate the 

limitations period for qui tam suits in which the United 

States does not intervene. The Court of Appeals held that

these suits are “civil action[s] under section 3730” and that

the limitations periods in §3731(b) apply in accordance 

with their terms, regardless of whether the United States

intervenes. It further held that, for purposes of the second 

period, the private person who initiates the qui tam suit 
 

2 COCHISE CONSULTANCY, INC. v. 

 UNITED STATES EX REL. HUNT 

Opinion of the Court 

cannot be deemed the official of the United States. We 

agree, and therefore affirm. 

I 

As relevant, the False Claims Act imposes civil liability 

on “any person” who “knowingly presents, or causes to be

presented, a false or fraudulent claim for payment or 

approval” to the Government or to certain third parties

acting on the Government’s behalf. 31 U. S. C. §§3729(a), 

(b)(2). Section 3730 authorizes two types of actions: First,

the Attorney General, who “diligently shall investigate a 

violation under section 3729,” may bring a civil action 

against the alleged false claimant. §3730(a). Second, a 

private person, known as a relator, may bring a qui tam

civil action “for the person and for the United States Government” against the alleged false claimant, “in the name 

of the Government.” §3730(b).

If a relator initiates the action, he must deliver a copy of

the complaint and supporting evidence to the Government,

which then has 60 days to intervene in the action.

§§3730(b)(2), (4). During this time, the complaint remains 

sealed. §3730(b)(2). If the Government intervenes, it 

assumes primary responsibility for prosecuting the action, 

though the relator may continue to participate. §3730(c).

Otherwise, the relator has the right to pursue the action.

§§3730(b)(4), (c)(3). Even if it does not intervene, the 

Government is entitled to be served with all pleadings 

upon request and may intervene at any time with good 

cause. §3730(c)(3). The relator receives a share of any 

proceeds from the action—generally 15 to 25 percent if the

Government intervenes, and 25 to 30 percent if it does

not—plus attorney’s fees and costs. §§3730(d)(1)–(2). See 

Vermont Agency of Natural Resources v. United States ex 

rel. Stevens, 529 U. S. 765, 769–770 (2000). 

At issue here is the Act’s statute of limitations, which 

provides: 
Cite as: 587 U. S. ____ (2019) 3 

Opinion of the Court 

“(b) A civil action under section 3730 may not be

brought—

“(1) more than 6 years after the date on which the

violation of section 3729 is committed, or 

“(2) more than 3 years after the date when facts material to the right of action are known or reasonably

should have been known by the official of the United

States charged with responsibility to act in the circumstances, but in no event more than 10 years after 

the date on which the violation is committed, 

“whichever occurs last.” §3731(b). 

On November 27, 2013, respondent Billy Joe Hunt filed 

a complaint alleging that petitioners—two defense contractors (collectively, Cochise)—defrauded the Government by submitting false claims for payment under a

subcontract to provide security services in Iraq “from some

time prior to January 2006 until early 2007.” App. 43a. A 

little less than three years before bringing his complaint, 

Hunt was interviewed by federal agents about his role in

an unrelated contracting fraud in Iraq. Hunt claims to 

have revealed Cochise’s allegedly fraudulent scheme 

during this November 30, 2010, interview. 

The United States declined to intervene in Hunt’s action, and Cochise moved to dismiss the complaint as

barred by the statute of limitations. Hunt conceded that 

the 6-year limitations period in §3731(b)(1) had elapsed

before he filed suit on November 27, 2013. But Hunt 

argued that his complaint was timely under §3731(b)(2) 

because it was filed within 3 years of the interview in

which he informed federal agents about the alleged fraud 

(and within 10 years after the violation occurred). 

The District Court dismissed the action. It considered 

three potential interpretations of §3731(b). Under the 

first interpretation, §3731(b)(2) does not apply to a relatorinitiated action in which the Government elects not to

 UNITED STATES EX REL. HUNT 

Opinion of the Court 

intervene, so any such action must be filed within six

years after the violation. Under the second interpretation, 

§3731(b)(2) applies in nonintervened actions, and the 

limitations period begins when the relator knew or should 

have known the relevant facts. Under the third interpretation, §3731(b)(2) applies in nonintervened actions, and 

the limitations period begins when “the official of the

United States charged with responsibility to act in the 

circumstances” knew or should have known the relevant 

facts. The District Court rejected the third interpretation 

and declined to choose between the first two because it 

found that Hunt’s complaint would be untimely under 

either. The Court of Appeals reversed and remanded,

adopting the third interpretation. 887 F. 3d 1081 (CA11 

2018).

Given a conflict between the Courts of Appeals,* we

granted certiorari. 586 U. S. ___ (2018). 

II 

The first question before us is whether the limitations 

period in §3731(b)(2) is available in a relator-initiated suit 

in which the Government has declined to intervene. If so, 

the second question is whether the relator in such a case 

should be considered “the official of the United States” 

whose knowledge triggers §3731(b)(2)’s 3-year limitations 

period. 

A 

Section 3731(b) sets forth two limitations periods that

apply to “civil action[s] under section 3730.” Both

Opinion of the Court 

Government-initiated suits under §3730(a) and relatorinitiated 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 agrees with that view as to the limitations 

period in §3731(b)(1), but argues that the period in 

§3731(b)(2) is available in a relator-initiated suit only if 

the Government intervenes. According to Cochise, 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 be read to apply

only when the Government is a party. In short, under 

Cochise’s reading, a relator-initiated, nonintervened suit 

is a “civil action under section 3730” for purposes of subsection (b)(1) but not subsection (b)(2).

This reading is at odds with fundamental rules of statutory interpretation. In all but the most unusual situations, a single use of a statutory phrase must have a fixed

meaning. See Ratzlaf v. United States, 510 U. S. 135, 143 

(1994). We therefore avoid interpretations that would 

“attribute different meanings to the same phrase.” Reno 

v. Bossier Parish School Bd., 528 U. S. 320, 329 (2000).

Here, either a relator-initiated, nonintervened suit is a 

“civil action under section 3730”—and thus subject to the 

limitations periods in subsections (b)(1) and (b)(2)—or it is 

not. It is such an action. Whatever the default tolling rule

might be, the clear text of the statute controls this case.

Under Cochise’s reading, a relator-initiated civil action 

would convert to “[a] civil action under section 3730” for 

purposes of subsection (b)(2) if and when the Government 

intervenes. That reading cannot be correct. If the Government intervenes, the civil action remains the same—it 

simply has one additional party. There is no textual basis 

to base the meaning of “[a] civil action under section 3730” 

on whether the Government has intervened. 
 

6 COCHISE CONSULTANCY, INC. v. 

 UNITED STATES EX REL. HUNT 

Opinion of the Court 

Cochise relies on our decision in Graham County Soil & 

Water Conservation Dist. v. United States ex rel. Wilson, 

545 U. S. 409 (2005), which addressed the question

whether §3731(b)(1) or federal common law provided the

limitations period for §3730(h) retaliation actions. Section 

3730(h) creates a cause of action for an employee who

suffers retaliation for, among other things, assisting with

the prosecution of a False Claims Act action. At the time, 

§3730(h) did not specify a time limit for bringing a retaliation action, so the question before us was whether the 

phrase “civil action under section 3730” in §3731(b) encompassed actions under §3730(h). We considered the 

statute “ambiguous because its text, literally read, admits

of two plausible interpretations.” Id., at 419, n. 2. One 

reading was that a “civil action under section 3730” includes §3730(h) actions because such actions arise under 

§3730. Id., at 415. “Another reasonable reading” was that

a “civil action under section 3730” “applies only to actions

arising under §§3730(a) and (b)” because “§3731(b)(1) 

t[ies] the start of the time limit to ‘the date on which the 

violation of section 3729 is committed.’” Ibid. That reading had force because retaliation claims need not involve 

an actual violation of §3729. Ibid. Looking to statutory 

context, we explained that the phrase “‘civil action under

section 3730’ means only those civil actions under §3730 

that have as an element a ‘violation of section 3729,’ that 

is, §§3730(a) and (b) actions”—not §3730(h) retaliation

actions. Id., at 421–422. 

A relator-initiated, nonintervened suit arises under 

§3730(b) and has as an element a violation of §3729. 

Graham County supports our reading. Nonetheless, Cochise points out that in considering the statutory context, 

we discussed a similar phrase contained in §3731(c) (now 

§3731(d)), which stated: “In any action brought under 

section 3730, the United States shall be required to prove

all essential elements of the cause of action, including 
 

Cite as: 587 U. S. ____ (2019) 7 

Opinion of the Court 

damages, by a preponderance of the evidence.” (Emphasis

added.) We explained that §3731(c) “use[d] the similarly 

unqualified phrase ‘action brought under section 3730’ to

refer only to §§3730(a) and (b) actions.” Id., at 417–418. 

We then stated: “As [respondent] and the United States

concede, the context of this provision implies that the 

phrase ‘any action brought under section 3730’ is limited 

to §3730(a) actions brought by the United States and 

§3730(b) actions in which the United States intervenes as

a party, as those are the types of §3730 actions in which 

the United States necessarily participates.” Id., at 418. 

Cochise contends that we should adopt a similar construction of the phrase “civil action under section 3730” in 

§3731(b). We disagree. Our discussion of §3731(c) was

focused on “the context of th[at] provision” and on whether

it could be read to impose the burden of proof on the Government even in cases where the Government did not 

participate. Id., at 418. Those considerations do not apply 

here; there is nothing illogical about reading §3731(b) to 

apply in accordance with its plain terms. Moreover, if a 

“civil action under section 3730” included only an action in 

which the Government participates for purposes of 

§3731(b)(2), then we would be obligated to give it a like 

meaning for purposes of §3731(b)(1). This would mean 

that a relator-initiated, nonintervened suit would be subject to neither §3731(b)(1) nor §3731(b)(2)—a reading

Cochise expressly disclaims. See Brief for Petitioners 20, 

n. 3. Nothing in Graham County supports giving the same

phrase in §3731(b) two different meanings depending on

whether the Government intervenes. 

Again pointing to Graham County, Cochise next contends that our reading would lead to “‘counterintuitive 

results.’” Brief for Petitioners 26. For instance, if the 

Government discovers the fraud on the day it occurred, it

would have 6 years to bring suit, but if a relator instead 

discovers the fraud on the day it occurred and the Gov-
 

8 COCHISE CONSULTANCY, INC. v.

 UNITED STATES EX REL. HUNT 

Opinion of the Court 

ernment does not discover it, the relator could have as 

many as 10 years to bring suit. That discrepancy arises 

because §3731(b)(2) begins its limitations period on the 

date that “the official of the United States charged with 

responsibility to act” obtained knowledge of the relevant 

facts. But we see nothing unusual about extending the 

limitations period when the Government official did not 

know and should not reasonably have known the relevant 

facts, given that the Government is the party harmed by

the false claim and will receive the bulk of any recovery.

See §3730(d). In any event, a result that “may seem odd 

. . . is not absurd.” Exxon Mobil Corp. v. Allapattah Services, Inc., 545 U. S. 546, 565 (2005). Although in Graham 

County we sought “a construction that avoids . . . counterintuitive results,” there the text “admit[ted] of two plausible interpretations.” 545 U. S., at 421, 419, n. 2. Here, 

Cochise points to no other plausible interpretation of the

text, so the “‘judicial inquiry is complete.’” Barnhart v. 

Sigmon Coal Co., 534 U. S. 438, 462 (2002). 

B 

Cochise’s fallback argument is that the relator in a

nonintervened suit should be considered “the official of the 

United States charged with responsibility to act in the 

circumstances,” meaning that §3731(b)(2)’s 3-year limitations period would start when the relator knew or should

have known about the fraud. But the statute provides no 

support for reading “the official of the United States” to 

encompass a private relator. 

First, a private relator is not an “official of the United 

States” in the ordinary sense of that phrase. A relator is 

neither appointed as an officer of the United States, see 

U. S. Const., Art. II, §2, cl. 2, nor employed by the United

States. Indeed, the provision that authorizes qui tam

suits is entitled “Actions by Private Persons.” §3730(b). 

Although that provision explains that the action is 
 

 

Cite as: 587 U. S. ____ (2019) 9 

Opinion of the Court 

brought “for the person and for the United States Government” and “in the name of the Government,” ibid., it 

does not make the relator anything other than a private

person, much less “the official of the United States” referenced by the statute. Cf. Stevens, 529 U. S., at 773, n. 4 

(“[A] qui tam relator is, in effect, suing as a partial assignee of the United States” (emphasis deleted)). 

Second, the statute refers to “the” official “charged with

responsibility to act in the circumstances.” The Government argues that, in context, “the” official refers to the 

Attorney General (or his delegate), who by statute “shall 

investigate a violation under section 3729.” §3730(a).

Regardless of precisely which official or officials the statute is referring to, §3731(b)(2)’s use of the definite article 

“the” suggests that Congress did not intend for any and all 

private relators to be considered “the official of the United

States.” See Rumsfeld v. Padilla, 542 U. S. 426, 434 

(2004) (explaining that the “use of the definite article . . . 

indicates that there is generally only one” person covered).

More fundamentally, private relators are not “charged

with responsibility to act” in the sense contemplated by

§3731(b), as they are not required to investigate or prosecute a False Claims Act action.

Appeals is 

Affirmed.
