Document Summary
Claimant's to Respondent on Payment with the Award
This summary note is machine-generated. Always consult the original materials.

Procedural Posture and Purpose

This document comprises a formal demand letter submitted by counsel for the Claimant, The AES Corporation, to the Argentine Republic, seeking prompt compliance with the arbitral award rendered on 30 May 2025 in ICSID Case No. ARB/02/17. The correspondence formally requests the execution of a wire transfer to satisfy the Respondent's pecuniary obligations under the Award, invoking the Respondent's binding obligation to comply with the Award pursuant to Article 53(1) of the ICSID Convention.

Principal Issues and Claimant's Position

The Claimant outlines the specific financial liabilities established by the Tribunal, which include US$715.9 million in principal damages, alongside continuous pre- and post-award interest calculated at the 1-year United States Treasury Bill rate. Furthermore, the letter details the Respondent's obligation to reimburse legal fees and expenses amounting to US$15,807,955.30, as well as arbitration costs of US$1,273,176.52. According to the Claimant's calculations, the total outstanding quantum, inclusive of accumulated interest as of 31 May 2025, amounts to US$819,057,549.

Operative Demands

The Claimant establishes a deadline of 13 June 2025 for the Respondent to confirm that full payment will be executed no later than 20 June 2025. The correspondence expressly reserves the Claimant's rights to initiate recognition and enforcement proceedings across relevant jurisdictions should the Respondent fail to remit the demanded sums voluntarily.

Document Summary
Petition to Enforce Arbitration Award
This summary note is machine-generated. Always consult the original materials.

Procedural Posture

This document is a Petition to Recognize and Enforce an ICSID Arbitration Award filed by AES Corporation against the Argentine Republic in the United States District Court for the District of Columbia. The Petitioner seeks to enforce a May 30, 2025 ICSID award rendered in its favor, which found Argentina in breach of the fair and equitable treatment and non-impairment standards under the Argentina-U.S. Bilateral Investment Treaty (BIT).

Legal Issues and Petitioner's Positions

The Petitioner asserts that the District Court possesses subject matter jurisdiction under the Foreign Sovereign Immunities Act (FSIA), 28 U.S.C. § 1330(a), arguing that Argentina is not entitled to sovereign immunity due to the FSIA's implied waiver and arbitral award exceptions (28 U.S.C. § 1605(a)(1) and (6)). The Petitioner further relies on 22 U.S.C. § 1650a, which grants federal courts exclusive jurisdiction over actions to enforce ICSID awards and mandates that such awards be given the same full faith and credit as a final judgment of a state court.

Anticipating potential defenses, the Petitioner emphasizes that under Article 53(1) of the ICSID Convention and the Federal Arbitration Act (FAA), the Court is strictly precluded from entertaining any substantive challenges or collateral attacks on the merits of the arbitral award. The Petitioner notes that the exclusive remedy for challenging an ICSID award is through the Convention's annulment mechanism, which Argentina has not pursued.

Relief Sought

The Petitioner requests the entry of an order recognizing and enforcing the ICSID award in its entirety. Specifically, the Petitioner seeks judgment for the unpaid damages of $715,900,000, legal fees of $15,807,955.30, and arbitration costs of $1,273,176.52, alongside applicable pre-award and post-judgment interest.

Document Summary
Declaration of James Hosking
This summary note is machine-generated. Always consult the original materials.

Procedural Posture

This document is a Declaration by James Hosking, counsel for Petitioner AES Corporation, submitted to the United States District Court for the District of Columbia. The declaration is filed in support of a Petition to Recognize and Enforce an ICSID Arbitration Award rendered against the Argentine Republic on May 30, 2025, in ICSID Case No. ARB/02/17.

Factual and Procedural Background

The declaration outlines the procedural history and factual basis of the underlying ICSID arbitration, which arose from Argentina's regulatory measures affecting the electricity generation sector following its 2001 economic crisis. The declarant notes that the arbitral tribunal unanimously found Argentina in breach of its obligations under Articles II.2.a and II.2.b of the Argentina-U.S. Bilateral Investment Treaty (BIT), specifically regarding fair and equitable treatment and the non-impairment of investments through arbitrary or discriminatory measures.

Relief Sought

The declaration affirms that the tribunal awarded the Petitioner $715,900,000 in damages, alongside interest and a partial allocation of legal costs, bringing the total outstanding amount to $824,397,132.86. Noting that Argentina has neither moved to annul the award nor made any payments to satisfy the judgment, the Petitioner formally seeks entry of a judgment from the District Court recognizing and enforcing the ICSID award pursuant to 28 U.S.C. § 1746.

Document Summary
Procedural Order No. 2
This summary note is machine-generated. Always consult the original materials.

Procedural Background

This document constitutes Procedural Order No. 2, issued by the ad hoc Committee in the annulment proceeding initiated by the Argentine Republic against The AES Corporation. Following the first session held by video conference on March 10, 2026, the Committee issued this Order to establish the procedural framework governing the annulment phase, applying the 1984 ICSID Arbitration Rules mutatis mutandis pursuant to Rule 53.

Procedural Rules and Directions

The Order delineates comprehensive logistical and procedural protocols, including the apportionment of advance payments, which the Applicant (Argentina) is directed to bear solely in the first instance, without prejudice to the final allocation of costs. The Committee designated Washington, D.C. as the formal place of proceedings and established English and Spanish as the dual procedural languages.

Furthermore, the Committee set strict parameters for the evidentiary record, emphasizing that annulment proceedings rely primarily on the underlying arbitration record. The introduction of new documentary evidence, witness statements, or expert reports is expressly prohibited absent a showing of special circumstances and subsequent Committee authorization. The Order concludes with a detailed procedural calendar (Annex B), scheduling the exchange of written submissions and reserving dates for the hearing on annulment in March 2027.

Document Summary
General Order for Civil Cases before the Honorable Reggie B. Walton
This summary note is machine-generated. Always consult the original materials.

Procedural Posture and Purpose

This document is a General Order issued by the United States District Court for the District of Columbia, establishing the mandatory procedural framework and rules of conduct for all civil cases assigned to the calendar of Judge Reggie B. Walton. The Order governs the proceedings in the enforcement action brought by AES Corporation against the Argentine Republic.

Procedural Directives and Court Requirements

The Order delineates strict compliance requirements regarding court communications, filing mechanics, and motion practice. It expressly prohibits ex parte communications with chambers and mandates that all motions be accompanied by a proposed order. The Court further outlines specific protocols for initial scheduling conferences, discovery dispute resolution, and the filing of administrative records. Notably, the Order establishes a presumption that all cases will be referred to alternative dispute resolution (ADR) and requires parties to engage in early settlement discussions.

Directives on Generative AI and Extrajudicial Statements

Addressing modern practice considerations, the Court permits the use of generative artificial intelligence tools but imposes strict ethical obligations on counsel to ensure the accuracy and completeness of all representations and citations. Violations of these obligations are subject to sanctions under Federal Rule of Civil Procedure 11(c). Additionally, the Order restricts counsel from making extrajudicial statements that are substantially likely to have a materially prejudicial effect on the proceedings, ensuring the integrity of the judicial process.
