Chilean Hydro Project Owner Overturns US Injunction in Global Arbitration

📅 2026-07-13 4 min read UCP 600 / ISBP 745

Introduction

When a Chilean hydro project owner obtained a global arbitration award and then sought enforcement in the United States, the respondent obtained a US injunction blocking enforcement. The project owner's successful appeal of that injunction demonstrates the limits of US courts' willingness to interfere with international arbitration awards.

Google News RSS surfaced a report from Global Arbitration Review confirming that the Chilean hydro project owner overturned the US injunction, with additional context from related GAR coverage of the case.

Failure Mode Analysis

Failure Mode 1: Assuming US courts will routinely interfere with international arbitration awards

US courts apply a strong presumption in favour of enforcing arbitration awards under the New York Convention and the FAA. An injunction blocking enforcement is an exception, not the norm. The respondent must meet a high burden.

Failure Mode 2: Using domestic litigation to relitigate the arbitration

The arbitration award is final and binding. Attempts to relitigate the merits of the dispute in US courts through injunction proceedings are disfavoured. The courts will assess the enforcement application on the Convention grounds, not on the underlying dispute.

Failure Mode 3: Failing to distinguish between the arbitration award and the enforcement proceeding

The arbitration award and the enforcement proceeding are separate. The enforcement proceeding assesses whether the award meets the Convention requirements. A party that conflates the two proceedings creates confusion and weakens its position.

Failure Mode 4: Overestimating the protection of a domestic injunction

A US injunction blocking enforcement does not necessarily block enforcement in other jurisdictions. The arbitration award remains enforceable worldwide; the injunction is limited to the US.

Deterministic Resolution Architecture

  1. Identify the specific grounds on which the US injunction was obtained.
  2. Assess whether those grounds meet the New York Convention requirements for refusing enforcement.
  3. Determine whether the injunction was based on merits arguments that should have been raised in the arbitration.
  4. Evaluate the strength of the enforcement application under the FAA.
  5. Prepare the appeal by addressing the specific legal errors in the injunction order.
  6. Monitor enforcement proceedings in other jurisdictions.
  7. Preserve the evidentiary record of the arbitration and the enforcement proceeding.

Conclusion

The overturning of the US injunction demonstrates that US courts will enforce international arbitration awards absent compelling grounds under the New York Convention. Parties seeking to block enforcement must meet a high burden. The arbitration award remains the final resolution of the dispute; the enforcement proceeding is a separate assessment.

FAQ

Can a US court block the enforcement of an international arbitration award?

Yes, but only on limited grounds under the New York Convention, such as public policy, lack of due process, or exceeding the scope of the arbitration agreement.

What is the standard for obtaining an injunction against enforcement?

The party seeking the injunction must demonstrate irreparable harm, a likelihood of success on the merits, and that the balance of equities favours injunctive relief.

Does the injunction affect enforcement in other countries?

No. The injunction is limited to the US. The award remains enforceable in other jurisdictions that are parties to the New York Convention.

Can the respondent relitigate the merits of the dispute in the enforcement proceeding?

No. The enforcement proceeding assesses whether the award meets the Convention requirements. The merits of the dispute were resolved in the arbitration.

What is the timeline for enforcement under the New York Convention?

The Convention requires courts to enforce awards unless the respondent raises specific grounds for refusal. The process varies by jurisdiction but is in most cases faster than relitigating the underlying dispute.
