Opinion for the Court filed by Circuit Judge GRIFFITH.
The district court dismissed the breach-of-contract claims of a government contractor, concluding they were barred by the statute of limitations in 41 U.S.C. § 605(a) and the equitable doctrine of laches. For the reasons set forth below, we reverse the judgment of the district court and remand for further proceedings consistent with this opinion.
I.
The Contract Disputes Act of 1978(CDA), 41 U.S.C. §§ 601 et seq. (2006), established a comprehensive framework for resolving contract disputes between executive branch agencies and government contractors. See id. § 602(a). In 1994, Congress amended the CDA to require, with one exception not relevant here, that all claims relating to a government contract be submitted, within six years of accrual, to the contracting officer responsible for entering and administering contracts on behalf of the relevant agency. See Federal Acquisition Streamlining Act of 1994, Pub.L. No. 103-355, § 2351(a), 108 Stat. 3243, 3322 (codified at 41 U.S.C. § 605(a)). 1
Once the contracting officer issues a decision on a claim or is deemed to have denied the claim by failing to issue a timely decision,
see
41 U.S.C. § 605(a), (c), a dissatisfied contractor has two options. The contractor may, within ninety days, appeal the decision to the board of contract appeals for the relevant agency.
Id.
§ 606. Or the contractor may, within twelve months, file suit in the United States Court of Federal Claims.
Id.
§ 609(a). Although these two paths are mutually exclusive,
Tuttle/White Constructors, Inc. v. United States,
*522 This appeal found its way to our court— and not our sister circuit — by an unconventional third route, made possible because the case involves a contract authorized by the Indian Self-Determination and Education Assistance Act (ISDEAA). See 25 U.S.C. §§ 450 et seq. The ISDEAA permits Indian tribes to assume responsibility for federally funded programs or services that a federal agency would otherwise provide to the tribes’ members. See id. §§ 450b(j), 450f(a). After the tribe and agency memorialize the transfer of authority in a “self-determination contract,” they negotiate annual funding agreements, which become part of the contract. Id. § 450Z(c) (subsection (f)(2) of model agreemеnt). Though self-determination contracts are governed by the CDA, id. § 450m-l(d), the ISDEAA allows a tribe to bring an action arising under its contract in the district court rather than the Court of Federal Claims. Id. § 450m-1(a). The tribe exercised that option in this case.
The parties to the contract at issue are the Menominee Indian Tribe of Wisconsin and the Indian Health Service (IHS), the agency tasked with administering federal health programs for American Indians. Pursuant to a contract with IHS, Menominee has for many years operated a healthcare program for its members. The tribe alleges that the IHS has failed to pay all the “contract support costs” (reasonable administrative expenses and the like) to which it was statutorily entitled for the 1995 tо 2004 contract years. Id. § 450j~ 1(a)(2) (obligating agencies to reimburse tribes’ contract support costs). Menominee submitted its claims to the IHS contracting officer on September 7, 2005. After the contracting officer denied the claims in their entirety, Menominee timely filed this action for breach of contract in the district court.
The government filed a motion to dismiss for lack of subject-matter jurisdiction and for failure to state a claim. The district court lacked jurisdiction over the claims for 1996, 1997, and 1998, the government contended, because Menominee had not filed those claims with the contracting officer until after the six-year limitations period in the CDA had expired. Becausе that deadline does not apply to “contracts awarded prior to October 1, 1995,” 48 C.F.R. § 38.206, the government argued that the tribe’s claim for 1995 was barred by laches.
Menominee did not disagree that it filed its claims for 1996 to 1998 more than six years after their accrual, but argued that the limitations period should be tolled. The tribe’s argument relied on the fact that in 1999 two other tribes filed a putative class action on behalf of all Indian tribes “that were not fully paid their contract support cost needs, as determined by IHS,” under a self-determination contract.
Cherokee Nation of Okla. v. United States,
The district court dismissed the claims for 1995 to 1998. See Menominee Indian Tribe of Wise. v. United States, 539 *523 F.Supp.2d 152 (D.D.C.2008). The court rejected Menominee’s class-action tolling theory on the ground that “presentment to the contracting officer is a mandatory jurisdictional requirement and was not timely performed by the Tribe for its 1996-1998 claims.” Id. at 154 n. 2 (citation omitted). The court also declined to equitably toll the filing deadline, reasoning that “[statutory time limits are jurisdictional in nature, and courts do not have the power to create equitable exceptions to them.” Id. at 154. With respect to the claim for 1995, the district court held that laches applied because the tribe’s “11-year delay in bringing suit [was] nearly double the time allowed under the statute of limitations,” id., and caused the government economic prejudice, id. at 154-55.
After the district court dismissed the tribe’s remaining claims, Menominee appealed the dismissal of its claims for 1995 to 1998. We have jurisdiction under 28 U.S.C. § 1291.
II.
We first consider the timeliness of Menominee’s claims for 1996 to 1998, which are subject to the statute of limitations in 41 U.S.C. § 605(a). Menominee missed its deadline but argues that the limitations period should be tolled. The government argues that the limitations period is jurisdictional and therefore cannot be tolled, equitably or otherwise. We disagree that the limitations period is jurisdictional but agree with the government’s alternative argument that class-action tolling is unavailable in this case. Nevertheless, we conclude that the limitations period in § 605(a) is subject to equitable tolling in appropriate cases and remand for the district court to consider whether it would be proper here. Our conclusions regarding thе availability of class-action and equitable tolling under § 605(a) are the same as those reached by the Federal Circuit in
Arctic Slope Native Ass’n v. Sebelius,
A. Jurisdiction
The district court treated the six-year deadline in § 605(a) as jurisdictional.
Menominee,
“Subject matter jurisdiction defines the [tribunal’s] authority to hear a given type of case.”
Carlsbad Tech., Inc. v. HIF Bio, Inc.,
— U.S.-,
The different treatment of claim-processing rules and jurisdictional requirements has significant effects on the scope of authority held by adjudicatory tribunals. Claim-processing rules “typically permit [tribunals] to toll the limitations period in light of special equitable considerations,”
John R. Sand,
Whether a statutory time limit or other prerequisite to suit is jurisdictional is “discerned by looking to the condition’s text, context, and relevant historical treatment.”
Reed Elsevier, Inc. v. Muchnick,
- U.S. -,
The time limit for initiating a claim under the CDA is not stated in jurisdictional terms. Section 605(a) provides that all claims by a contractor “shall be in writing”; “shall be submitted to the contracting officer for a decision”; and “shall be submitted within 6 years after the accrual of the claim.” 41 U.S.C. § 605(a). The statute does not “refer in any way to ... jurisdiction,”
Zipes v. Trans World Airlines, Inc.,
The government asks the court to infer from the structure of the statutory regime for processing government contract claims that the limitations period in § 605(a) is jurisdictional. Specifically, the government argues that tolling the six-year deadline in § 605(a) would “undermine” 28 U.S.C. § 2501, Appellee’s Br. at 25, which generally limits the jurisdiction of the Court of Federal Clаims to claims filed
*525
within six years of their accrual.
John R. Sand, 552
U.S. at 134-38,
Likewise, the historical treatment of the type of limitation imposed by § 605(a) does not suggest that its six-year filing deadline is jurisdictional. In
John R. Sand, & Gravel Co. v. United States
and
Bowles v. Russell
the Supreme Court recognized the general rule that timе requirements do not affect subject-matter jurisdiction but concluded that the particular time limits at issue in those cases were jurisdictional based on their historical treatment.
See John R. Sand,
The government also makes a broader argument: that § 605(a) “run[s] for the benefit of the Government” and this type of time limit has “long been considered jurisdictional.” Appellee’s Br. at 13. The government has it precisely backwаrds.
Irwin v. Department of Veterans Affairs
established a “general rule” that time limits for suing the government are presumptively subject to equitable tolling,
Finally, the government argues that the limitations period in § 605(a) is jurisdictional because it facilitates administrative review and promotes judicial efficiency. That may be so, but such virtues do not make the limitations period jurisdictional. Many time limitations-including claim — processing rules — serve “system-related goal[s] such as facilitating the administration of claims,”
John R. Sand,
Because the time limit in § 605(a) is not jurisdictional in nature, the district court erred in dismissing Menominee’s claims for lack of subject-matter jurisdiction. We may still affirm, however, if we conclude that the district court should have dismissed for failure to state a claim.
EEOC v. St. Francis Xavier Parochial Sell.,
B. Class-Action Tolling
In
American Pipe & Construction Co. v. Utah,
the Supreme Court held “that the commencement of a class action” will in some cases “suspend[ ] the applicаble statute of limitations as to all asserted members of the class who would have been parties had the suit been permitted to continue as a class action.”
A party generally must exhaust administrative remedies before seeking relief in federal court.
See McCarthy v. Madigan,
Menominee contends that the pendency of the
Cherokee
class action brought by other Indian tribes against the IHS tolled the limitations period in § 605(a) for all putative class members, including Menominee, under
American Pipe.
At the same time, Menominee acknowledges that it did not submit its claims to the contracting officer until after class certification was denied, and it concedes that the submission of such a claim is a jurisdictional prerequisite to judicial review. Appellant’s Br. at 42 n. 17.
3
It follows that Menominee should have been excluded
*527
from the
Cherokee
class, had one been certified, because the tribe had not satisfied the jurisdictional exhaustion requirement. In arguing otherwise, the tribe relies on cases permitting class-action tolling of the administrative filing deadlines in Title VII and the Age Discrimination in Employment Act (ADEA).
See Armstrong v. Martin Marietta Corp.,
Menominee further argues that even if the
Cherokee
court could not have exercised jurisdiction over its claims, class-action tolling of the period for filing an administrative claim is nevertheless required. In keeping with this court’s “functional reading of
American Pipe,” McCarthy v. Kleindienst,
American Pipe
addressed what effect, if any, the timely filing of a complaint on behalf of an asserted class should have on the statute of limitations governing the claims of absent class members — a problem that arises from the delay between the commencement of the action and the district court’s determination “whether to certify the action as a class action” and how to “define the class and the class claims.” Fed.R.CivP. 23(c)(1)(B). If the statute of limitаtions on the claims of putative class members continued to run in the meantime, the unnamed plaintiffs would face a choice: act to preserve their rights (by moving to intervene or join or by initiating a separate action) or run the risk of forfeiting their rights if class certification is denied after their claims have grown stale. The
American Pipe
Court held that, where a class is certified, the commencement of the action by the named plaintiff satisfies the statute of limitations “as to all those who might subsequently participate in the suit.”
A contrary rule would defeat Rule 23’s objectives of “efficiency and economy of litigation” by forcing putative class members to file protective motions to intervene
*528
in the pending action or run the risk of their claims growing stale.
American Pipe,
We agree with the Federal Circuit that the
American Pipe
doctrine does not require courts to toll the time putative class members have to satisfy a jurisdictional prerequisite to judicial review when the failure to do so precludes them from obtaining relief via the class action.
See Arctic Slope,
Menominee contends that extending class-action tolling to the time limitation in § 605(a) would advance the goal of “efficiency and economy of litigation” described by the Court in
American Pipe,
Menominee further argues that the district court in Cherokee “conclusively decided the parameters of the putative class[,] ... that the Tribe was a member of that class,” and that the issue “cannot be re-litigated.” Reply Br. at 4-5 & n. 1. That argument has no merit. The Cherokee court denied class certification and therefore never defined a class. See Fed. R.CivP. 23(c)(1)(B).
*529
Finally, Menominee contends that class-action tolling should apply here because the tribe’s failure to present a timely claim resulted from its reliance upon the
Cherokee
class action and arguments the government allegedly made in the course of that litigation.
See
Appellant’s Br. at 17; Reply Br. at 6. But Menominee’s purported reliance on the pendency of the class action is not germane to the availability of class-action tolling, which benefits even those “asserted class members who were unaware of the proceedings brought in their interest or who demonstrably did not rely on the institution of those proceedings.”
American Pipe,
In sum, Menominee advocates extending the benefit of tolling to all members of the class described by the named plaintiff, including those jurisdictionally barred from participation due to their failure to exhaust administrativе remedies. Such a rule would serve only one function: Permitting plaintiffs who could not have participated in the class to initiate actions against the government after their claims have grown stale. Adopting the rule Menominee advances would not further the objectives of Rule 23 but rather “invit[e] abuse” of the class device by encouraging lawyers “to frame their pleadings ... [to] save members of the purported class who have slept on their rights.”
Crown, Cork & Seal,
C. Equitable Tolling
In the alternative, Menominee argues that the CDA’s six-year limitations period should be equitably tolled. We agree that the statute is subject to tolling and remand for the district court to consider whether tolling is appropriate in this case.
“It is hornbook law that limitations periods are customarily subject to equitable tolling unless tolling would be inconsistent with the text of the relevant statute.”
Young v. United States,
The requirement that all claims “shall be submitted within 6 years after the accrual of the claim,” 41 U.S.C. § 605(a), reads like a run-of-the-mill statute of limitations. Because this provision was enacted after
Irwin
established the presumption in favor of equitable tolling, Congress was on notice that courts would read § 605(a) to permit tolling unless it provided otherwise.
See Holland,
The government argues that § 605(a) is much like the statute at issue in
United States v. Brockamp,
in which the Supreme Court held that the
Irwin
presumption had been rebutted even though Congress had not expressly precluded tolling.
Brockamp
involved the time limitation for filing claims for tax refunds.
See
26 U.S.C. § 6511. In holding that Congress did not want the deadline equitably tolled, the Court relied on several factors including the provision’s “detail, its technical language, the iteration of the limitations in both procedural and substantive forms, and the explicit listing of exceptions,”
The government describes the CDA as “a detailed, technical, complex scheme that sets forth precise procedures and deаdlines for the assertion of a claim.” Appellee’s Br. at 31. Be that as it may, the government’s focus on the regulatory scheme as a whole is misplaced. The
Brockamp
Court did not concern itself with the complexity of the Tax Code taken as a whole, but the complexity of the time limitations found in § 6511.
See
The
Brockamp
Court also drew on the several “explicit exceptions to [the] basic time limits” in § 6511 to conclude that it would be inappropriate to allow equitable tolling.
*531 We agree with the Federal Circuit that the time limitation in § 605(a) is subject to equitable tolling. Because the parties dispute facts relevant to application of the equitable tolling doctrine, we remand for the district court to determinе whether tolling is appropriate under the circumstances of this case.
III.
Neither party suggests that Menominee’s claim for 1995 is subject to the CDA’s six-year time limit, which is inapplicable to “contracts awarded prior to October 1, 1995.” 48 C.F.R. § 33.206. The district court still dismissed Menominee’s claim for 1995, but it did so based on the doctrine of laches.
The equitable defense of laches “is designed to promote diligence and prevent enforcement of stale claims” by those who have “ ‘slumber[ed] on their rights.’ ”
Gull Airborne Instruments, Inc. v. Weinberger,
The parties dispute the applicable standard of review. Menominee urges us to review the dismissal de novo, and the government advocates review under an abuse-of-discretion standard. We have observed that “both standards are relevant” when the district court’s laches determination comes at summary judgment,
Harjo,
First, the district court incorrectly calculated the length of the tribe’s delay. As the government now acknowledges, the tribe submitted its claim for 1995 “nine years and nine months after the claims accrued,” Appellee’s Br. at 43, not the eleven years suggested by the district court.
Cf. Gull Airborne,
Second, the district court erred in failing to consider the tribe’s arguments that its delay was reasonable. “[L]aches is not, like limitation, a mere matter of time,”
Holmberg v. Armbrecht,
Third, the district court provided inadequate reasons for concluding that Menominee’s delay prejudiced the government. The court оffered only the terse observation that “[fjunding for the 1995 contract year has long since expired.”
Menominee,
We close by noting that “a motion to dismiss generally is not a useful vehicle for raising the issue [of laches].” 5 Charles Alan Wright
&
Arthur R. Miller, Federal Practice and Procedure § 1277, at 644 (3d ed.2004).
But see, e.g., Love v. Stevens,
IV.
The dismissal of Menominee’s claims is reversed and the case is remanded for further proceedings consistent with this opinion.
So ordered.
Notes
. As amended, section 605(a) of Title 41, titled "Contractor claims,” reads in relevant part:
All claims by a contractor against the government relating to a contract shall be in writing and shall be submitted to the contracting officer for a decision. All claims by the government against a contractor relating to a contract shall be the subject of a decision by the contracting officer. Each claim by a contractor against the government relating to а contract and each claim by the government against a contractor relating to a contract shall be submitted within 6 years after the accrual of the claim. The preceding sentence does not apply to a claim by the government against a contractor that is based on a claim by the contractor involving fraud. The contracting officer shall issue his decisions in writing, and shall mail or otherwise furnish a copy of the decision to the contractor. The decision shall state the reasons for the decision reached, and shall inform the contractor of his rights as provided in this chapter. Specific findings of fact are not required, but, if made, shаll not be binding in any subsequent proceeding.
41 U.S.C. § 605(a) (emphasis added).
. In dismissing for lack of subject-matter jurisdiction, the district court implicitly concluded that the time limitation in § 605(a) demarcates the jurisdiction of the reviewing court, not only the jurisdiction of the contracting officer. Our holding that the time limit is not jurisdictional eliminates the need for us to doubt the district court's conclusion. In any event, the distinction between jurisdictional requirements and claim-processing rules applies.
See Union Pacific,
. The concession is well taken. The Federal Circuit and the Court of Claims have long held that the court may not exercise jurisdiction until the contracting officer either issues a decision on the claim or is deemed to have denied it.
See Bath Iron Works Corp. v. United States,
. The government also argues that tolling the limitations period in § 605(a) would undermine the statute of limitations for filing actions in the Court of Federal Claims, 28 U.S.C. § 2501, which cannot be equitably tolled,
