UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA

SIGMA CONSTRUCTORES, S.A.,

Plaintiff,

Civil Action No. 24 - 3055 (SLS)

v. Judge Sparkle L. Sooknanan

REPUBLIC OF GUATEMALA, Defendant.

MEMORANDUM OPINION

This case involves two treaties ratified by the United States: the U.N. Convention on the Recognition and Enforcement of Foreign Arbitral Awards (New York Convention) and the Inter- American Convention on International Commercial Arbitration (Panama Convention). Together, these treaties espouse an emphatic federal policy in favor of arbitral dispute resolution and establish an international legal regime to ensure the efficient satisfaction of arbitral awards in signatory countries. Congress has implemented both treaties in the Federal Arbitration Act (FAA).

Relying on this framework, Sigma Constructores, S.A. (Sigma), a construction and engineering company, sued the Republic of Guatemala to enforce an arbitral award that resolved a dispute between the Parties over the early termination of a highway construction contract. The arbitral award was rendered in Guatemala, which is a party to both the New York and Panama Conventions. In parallel proceedings, Guatemala is currently challenging that arbitral award in its domestic courts.

Guatemala now seeks to dismiss this action for lack of subject matter jurisdiction or personal jurisdiction under the Federal Sovereign Immunities Act (FSIA). In the alternative, Guatemala asks this Court to dismiss this action under the forum non conveniens doctrine or to

stay proceedings pending the ongoing judicial proceedings in Guatemala. Because none of these arguments are availing, the Court denies Guatemala’s motion in its entirety. Sigma’s petition falls squarely within the framework set out in the FAA and the New York and Panama Conventions. Thus, the Court is required to exercise jurisdiction in this case. And the Court expects to move expeditiously in resolving this dispute.

BACKGROUND

A. Statutory Background 1. Foreign Sovereign Immunities Act (FSIA)

“For much of the Nation’s history, the United States adhered to the ‘classical’ or ‘absolute’

theory of foreign sovereign immunity,” where “foreign states were generally granted complete immunity from suit.” Republic of Hungary v. Simon, 604 U.S. 115, 119 (2025) (cleaned up). “This posture reflected the venerable international law principle that states are independent sovereign entities, and it encouraged others to respect the sovereignty of the United States in their courts.” CC/Devas (Mauritius) Ltd. v. Antrix Corp., 605 U.S. 223, 228 (2025). But in the mid-20th Century, “an emerging consensus . . . developed among nations” favoring a “restrictive theory” of sovereign immunity, where “a foreign sovereign generally is immune from civil suit for sovereign acts but not for its commercial acts.” Simon, 604 U.S. at 119. And in 1952, the State Department “announced the United States’ decision to join the majority of other countries by adopting the ‘restrictive theory’ of sovereign immunity.” Permanent Mission of India to the United Nations v. City of New York, 551 U.S. 193, 199 (2007).

“While this shift brought the United States into parity with the emerging international consensus, it also provoked tension and confusion.” Antrix, 605 U.S. at 229. Courts “relied heavily upon the advice of [the Executive] branch when deciding just when and how th[e] ‘restrictive’ sovereign immunity doctrine applied.” Bolivarian Republic of Venezuela v. Helmerich & Payne

Int’l Drilling Co., 581 U.S. 170, 180 (2017). But “[f]oreign nations often placed diplomatic pressure on the State Department, and, on occasion, political considerations led to suggestions of immunity in cases where immunity would not have been available. Furthermore, in instances where the State Department simply failed to file any suggestion, courts were forced to determine immunity based on standards that were neither clear nor uniformly applied.” Antrix, 605 U.S. at 229 (cleaned up).

“Congress addressed the problem in 1976 by enacting the FSIA[.]” Id. That statute “codif[ied] . . . international law at the time of [its] enactment” by statutorily adopting the “restrictive view of sovereign immunity.” Permanent Mission, 551 U.S. at 199. “Instead of case- by-case determinations that were governed by fuzzy legal standards and prone to manipulation, the FSIA imposes a bright-line rule: foreign states and their instrumentalities are immune from suit unless one of the Act’s enumerated exceptions applies.” Antrix, 605 U.S. at 229. “The Act for the most part embodies basic principles of international law long followed both in the United States and elsewhere,” Helmerich & Payne Int’l Drilling, 581 U.S. at 179, and serves as “the sole basis for obtaining jurisdiction over a foreign state in our courts,” Antrix, 605 U.S. at 229 (citation omitted).

2. New York Convention The New York Convention is a multinational treaty that seeks “to encourage the recognition and enforcement of commercial arbitration agreements in international contracts and to unify the standards by which agreements to arbitrate are observed and arbitral awards are enforced in the signatory countries.” Scherk v. Alberto-Culver Co., 417 U.S. 506, 520 n.15 (1974). The New York Convention was designed to replace and succeed the preceding League of Nations Geneva Convention on the Execution of Foreign Arbitral Awards, Sep. 26, 1927, 92 L.N.T.S. 301

(Geneva Convention). See Charles H. Sullivan, 1958 Report of the U.S. Delegation to the United Nations Conference on International Commercial Arbitration, Office of the Legal Advisor U.S. Department of State, reprinted in 19 Am. Rev. Int’l Arb. 91, 94 (2008) (1958 State Department Delegation Report).

Specifically, the New York Convention sought to eliminate hurdles to the confirmation and enforcement of arbitral awards in light of concerns that “[t]he continuing expansion of world trade and the acceleration of the commercial process had . . . caused the business community to regard the provisions of the [Geneva] Convention as inadequate.” United Nations Conference on International Commercial Arbitration, Summary Record of the First Meeting 3–4, U.N. Doc. E/CONF.26/SR.1 (Sep. 12, 1958). “The primary defect of the Geneva Convention was that it required an award first to be recognized in the rendering state before it could be enforced abroad, the so-called requirement of ‘double exequatur.’” Yusuf Ahmed Alghanim & Sons v. Toys “R” Us, Inc., 126 F.3d 15, 22 (2d Cir. 1997) (citation omitted). So a party needed the “court of the country of origin” to either render a judgment or otherwise “give leave” in order “to allow enforcement” of the arbitral award elsewhere. Karaha Bodas Co. v. Perusahaan Pertambangan Minyak Dan Gas Bumi Negara, 335 F.3d 357, 367 n.41 (5th Cir. 2003). “This requirement was an unnecessary time-consuming hurdle, and greatly limited the Geneva Convention’s utility.” Yusuf Ahmed Alghanim & Sons, 126 F.3d at 22 (cleaned up). The Geneva Convention also “placed the burden of proof on the party seeking enforcement of a foreign arbitral award and did not circumscribe the range of available defenses to those enumerated in the convention.” Parsons & Whittemore Overseas Co. v. Societe Generale De L’Industrie Du Papier, 508 F.2d 969, 973 (2d Cir. 1974).

The New York Convention resolved these issues. Most importantly, it “eliminate[d]” the requirement of “double exequatur” altogether. 1958 State Department Delegation Report, 19 Am.
