D.C. Circuit Adopts Twelve-Year Statute of Limitations for Enforcing ICSID Awards
August 6, 2026

Signing of the International Centre for Settlement of Investment Disputes (ICSID) Convention
Last week, the D.C. Circuit held in Titan Consortium 1 v. Argentine Republic that suits brought in the District of Columbia to enforce arbitral awards issued by the International Centre for the Settlement of Investment Disputes (“ICSID”) are subject to a twelve-year statute of limitations. Both the rule and reasoning in Titan Consortium underscore the unique enforcement process for ICSID awards, how it differs from the process under the New York Convention, and the very different limitations periods that apply to enforcing ICSID and non-ICSID awards against foreign sovereigns.
The Basics of ICSID
ICSID was created in 1965 by the Convention on the Settlement of Investment Disputes Between States and Nationals of Other States, often called the ICSID Convention or the Washington Convention. ICSID only arbitrates investor-state disputes – “legal dispute[s] arising directly out of an investment, between a Contracting State … and a national of another Contracting State.” But although ICSID’s ambit is limited, its awards are potent. Under the ICSID Convention, no national court can vacate an ICSID award; rather, all review of an award is conducted by an internal “annulment committee.” And enforcement of ICSID awards is mandatory: Article 54 of the Convention provides that signatories “shall recognize” an ICSID award “as if it were a final judgment of a court in that State,” with no exceptions. Both of those features of the ICSID regime contrast with the New York Convention, the principal treaty governing non-ICSID international arbitral awards. That treaty permits courts in the arbitral seat to vacate an award, and Article V sets out several (narrow) grounds on which other states can refuse to enforce an award.
The United States ratified the ICSID Convention and created a federal cause of action to enforce ICSID awards, codified at 22 U.S.C. §1650a. Tracking the Convention, §1650a provides that such awards “shall be enforced” and “given the same full faith and credit as if the award were a final judgment of a court of general jurisdiction of one of the several States.”
The Titan Consortium Decision
The facts in Titan Consortium follow a familiar pattern. Three Spanish companies invested in Argentina’s airline industry. Argentina then imposed price caps and other policies that severely depressed the value of the investments, and ultimately bought out the investors. The investors initiated arbitration at ICSID, alleging expropriation of their property. The shareholders prevailed, winning a $320 million award they assigned to Titan Consortium 1. Four years after the award was issued, Titan brought suit in the U.S. District Court for the District of Columbia to enforce the award in the United States. Argentina moved to dismiss, arguing that Titan’s suit was time-barred.
Neither the ICSID Convention nor §1650a prescribe a statute of limitations, so the district court borrowed a twelve-year limitations period from D.C. Code §15-101. Titan’s suit was easily timely under that rule, and the court ultimately enforced the award. Argentina appealed on the timeliness question.
The D.C. Circuit affirmed, in an opinion by Judge Patricia Millett. When a federal cause of action does not prescribe a statute of limitations, the court explained, federal courts borrow “the most closely analogous statute of limitations,” with a presumption favoring state law unless a federal rule is both clearly the closest analogue and federal policy interests render that rule “significantly more appropriate.” Here, the D.C. Circuit agreed with Titan and the district court that D.C. Code §15-101 was the most closely analogous statute of limitations.
Section 15-101 provides that “every final judgment or final decree for the payment of money” rendered by a D.C. federal or local court is “enforceable, by execution issued thereon, for the period of twelve years only from the date when an execution might first be issued thereon.” According to the D.C. Circuit, this law thus covers the “same types of pecuniary obligations as those covered by Section 1650a.” And when a federal court “enforce[s] a judgment pursuant to the terms of Section 15-101,” the D.C. Circuit said, it is “affording a D.C. judgment full faith and credit,” just as §1650a requires courts to treat ICSID awards. Finally, §15-101 does not contemplate any discretion to act on the judgment or not, mirroring the mandatory enforcement regime for ICSID awards and for out-of-state judgments.
The D.C. Circuit then rejected Argentina’s two proffered alternatives: §207 of the Federal Arbitration Act, which establishes a three-year statute of limitations for petitions to enforce awards under the New York Convention; and the D.C. Arbitration Act, which Argentina argued is subject to D.C.’s three-year catch-all limitations period.
Although the first alternative was intuitively appealing, the court noted several problems with borrowing §207’s three-year limitations period. For one, §1650a expressly states that the FAA “shall not apply” to ICSID awards; conversely, chapter 2 of the FAA is explicitly limited to awards governed by the New York Convention. Further undercutting the analogy, the FAA incorporates the New York Convention’s standards for deciding whether to enforce an award – an approach the ICSID Convention specifically rejected in favor of mandatory enforcement.
Nor was the court convinced that the policy interest in a uniform limitations rule justified borrowing from federal law. Congress had every opportunity to prescribe a uniform rule and hadn’t done so. Moreover, any concern about disuniformity was “more theoretical than practical,” since the Foreign Sovereign Immunities Act’s venue provisionswould funnel suits to enforce ICSID awards (which by definition will nearly always involve a “foreign state” subject to the FSIA) to the District of Columbia.
Finally, the court expressed practical concerns about a three-year limitations period. Because review by an ICSID annulment committee can take several years, an award holder might be time-barred in the U.S. by the time that review concluded. The panel was not swayed by the option to file an enforcement action and seek a stay from the court while internal review proceeds – it even suggested that such an action might not be justiciable as unripe. (The court did not mention that this is precisely what petitioners under the New York Convention must do when set-aside proceedings are pending at the arbitral seat.)
The D.C. Circuit also declined to borrow a limitations period from the D.C. Arbitration Act. The biggest problem, the court explained, was that that Act does not have an express limitations period for enforcement petitions. But even assuming (as Argentina did) that D.C. Code §12-301(8)’s catch-all three-year limitations period applied, that analogue had many of the same problems as §207. The court reiterated its concern that three years is unworkably short, and it noted that the D.C. Arbitration Act contains even more grounds to refuse enforcement than the New York Convention, again contrary to ICSID’s mandatory enforcement regime.
And yet, the court’s preferred analogue is not a perfect fit either. Section 15-101 is not actually about “enforcement” in the relevant sense of reducing an obligation to a judgment in a particular jurisdiction. Rather, §15-101 governs execution on existing judgments, barring execution on D.C. judgments older than twelve years. It does not address when or how a party can obtain an executable judgment based on an out-of-state judgment or arbitral award.
The court addressed this problem only obliquely, explaining that the District’s process for enforcing sister-state judgments “will not work for Washington Convention awards” because D.C. borrows the issuing state’s limitations period for such actions. But the opinion appears to conflate two related but meaningfully distinct usages of the word “enforcement”: reducing an arbitral award to judgment in a particular jurisdiction (as used in §1650a) versus executing on a judgment that is already valid in the jurisdiction (as used in §15-101). Or perhaps the court recognized the problem but concluded that, of the options presented, §15-101 was still “the closest, albeit imperfect, statute of limitations analogue.” One wonders if the D.C. Circuit felt about §15-101 the way Winston Churchill felt about democracy: It’s the worst analogue, except for all the others.
Comparing the New York Convention
Titan Consortium’s limitations rule underscores the contrast between the ICSID enforcement and the New York Convention’s – and the desirability of the ICSID regime. As the D.C. Circuit repeatedly noted, a key feature of the ICSID Convention is its non-discretionary enforcement mandate. Suits under §1650a thus do not involve the debates about public policy or procedural fairness often seen in New York Convention proceedings under chapter 2 of the FAA. And now, ICSID award holders also benefit from a limitations period four times longer than the FAA’s. That is a significant boon: As my colleague Robert Kry explained at TLB last year, the FAA’s three-year statute of limitations is far shorter than the rule in most jurisdictions and can pose practical obstacles for a multi-jurisdictional enforcement and recovery strategy.
The contrast between ICSID and non-ICSID enforcement is especially stark for award creditors of foreign states. Award holders can sometimes skirt the FAA’s three-year limitations period by first enforcing the award in another country and then seeking U.S. recognition of that judgment under a state law with a longer limitations period. The Fourth Circuit’s recent decision in J. Robert van Faassen, LLM v. Lindberg perfectly illustrates this strategy. Four years after winning an arbitral award, the award holder applied to enforce the award under the FAA and to recognize a Dutch judgment confirming the award using a North Carolina law with a ten-year limitations period. The Fourth Circuit held the FAA petition was untimely but approved the award holder’s attempt to recognize the foreign judgment.
But that strategy is not available against foreign states in the D.C. Circuit. In Amaplat Mauritius Ltd. v. Zimbabwe Mining Development Corp., the D.C. Circuit split with the Second Circuit and held that neither the arbitration nor waiver exceptions to foreign sovereign immunity apply to actions to enforce a foreign judgment, even when that judgment is itself based on an arbitral award. As a result, to enforce their awards in the United States, holders of non-ICSID awards against foreign states must use the FAA and comply with its three-year limitations period. Yet after Titan Consortium, a similarly situated party holding an ICSID award has twelve years to enforce its award in the United States.
Conclusion
Titan Consortium is thus an important decision for the victors of ICSID arbitrations, allowing them to structure their enforcement and recovery strategies without the pressure of enforcing their awards in the United States within three years. More generally, Titan Consortium’s outcome and reasoning underscore the differences between the ICSID enforcement regime and the New York Convention, especially for award creditors of foreign states in light of Amaplat Mauritius.
