Investment Awards vs Sovereign Immunity: Navigating the Enforcement Maze

By Cara North, Counsel, Ashurst

The intersection of international State immunity and the enforcement of worldwide arbitral awards has been a hotly contested points in recent times. First the query was whether or not a State has waived immunity from courtroom processes regarding recognition and enforcement of arbitral awards by ratifying the 1965 Conference of Settlement of Funding Disputes (ICSID Conference) – to which the reply has been sure in Australia and the  England and Wales (amongst different jurisdictions). Extra lately, the query has been whether or not a State’s ratification of the 1958 New York Conference on the Recognition and Enforcement of Overseas Arbitral Awards (New York Conference) constitutes an implicit waiver of sovereign immunity, to which the Excessive Court docket of Australia most lately held no.

In CCDM Holdings, LLC v The Republic of India [2026] HCA 9, the Excessive Court docket of Australia unanimously held that ratification of the New York Conference doesn’t, of itself, waive international State immunity below the Overseas States Immunities Act 1985 (Cth). The choice aligns Australia with the present place in the USA, Canada, and England and Wales, reinforcing an rising frequent legislation consensus in that regard.

Factual and Procedural Background

The dispute arose from an funding by Mauritian corporations in an Indian Authorities-owned company. In 2011, the Indian Authorities annulled the underlying settlement on public coverage and nationwide safety grounds. The buyers commenced arbitral proceedings in opposition to India below Article 8 of the India-Mauritius bilateral funding treaty (BIT), which contemplated ICSID arbitration. As India shouldn’t be a Contracting State to the ICSID Conference, the arbitration proceeded below UNCITRAL Guidelines.

In 2020, the tribunal rendered an award of US$111 million. The award collectors sought enforcement in Australia below the New York Conference. India resisted, invoking immunity below part 9 of the Overseas States Immunities Act 1985 (Cth).

The Waiver Query within the Decrease Courts

At first occasion, Jackman J held that India had waived immunity by ratifying the New York Conference, discovering a “clear” and “unmistakable” implication—notably from Article III, learn with Articles I(1) and II(1)—that ratification concerned waiver and submission to the jurisdiction of different Contracting States.

On attraction, the Full Federal Court docket didn’t determine the waiver query definitively. It assumed ratification constituted a waiver, however held that India’s reservation—limiting the Conference to disputes “thought-about industrial below the Regulation of India”—circumscribed any such waiver. Discovering the dispute was not industrial below Indian legislation, it held that India had not waived immunity in respect of the award.

The Excessive Court docket’s Evaluation

The Excessive Court docket addressed the basic query immediately: whether or not ratification of the New York Conference is able to constituting a waiver of international State immunity.

The governing precept is that any waiver in a world settlement have to be “clear and unmistakeable”, derived from the categorical phrases of the settlement, together with mandatory implications.

The Excessive Court docket noticed that the textual content of the New York Conference comprises no categorical reference to international State immunity. The travaux préparatoires revealed an intention to protect immunity within the courts of different States—a consideration militating in opposition to implied waiver.

Crucially, the Court docket examined Article III, which requires Contracting States to recognise awards as binding and implement them “in accordance with the principles of process of the territory the place the award is relied upon”. The Excessive Court docket held this phrase encompasses international State immunity guidelines, qualifying the enforcement obligation by reference to immunity guidelines within the related discussion board.

The Court docket additionally thought-about subsequent State follow below Article 31(3)(b) of the Vienna Conference on the Regulation of Treaties. It discovered that choices from the USA, Canada, and England and Wales pointed in the wrong way: ratification of the New York Conference shouldn’t be, by itself, a ample act of waiver.

Distinguishing the ICSID Conference

The appellants sought to attract an analogy with Kingdom of Spain v Infrastructure Companies Luxembourg Sàrl [2023] HCA 11, the place Spain was held to have waived immunity by ratifying the ICSID Conference. The Excessive Court docket rejected this analogy, figuring out materials distinctions:

First, the ICSID Conference is expressly involved with disputes to which a State is a celebration, and its travaux préparatoires addressed international State immunity intimately.
Second, Article 55 of the ICSID Conference preserves immunity solely from execution—implying waiver of immunity from recognition and enforcement. Article III of the New York Conference helps preservation of immunity from jurisdiction altogether.

Third, the Worldwide Regulation Fee supplies relied upon by the appellants didn’t equate the 2 Conventions in any dispositive approach.

Implications for Enforcement In opposition to States

CCDM Holdings supplies an authoritative demarcation between the 2 principal conventions. For ICSID awards, Kingdom of Spain establishes that enforcement in opposition to a Contracting State in Australia won’t be barred by claims of immunity from jurisdiction. For non-ICSID awards—together with funding treaty awards below UNCITRAL or different guidelines—enforcement in opposition to an unwilling State below the New York Conference is foreclosed absent clear and unmistakeable waiver.

Buyers should give cautious consideration to the provision of ICSID arbitration when contracting with States. The place unavailable, events ought to search clear waivers of immunity if enforcement in Australia or related jurisdictions is contemplated.

Conclusion

The Excessive Court docket’s unanimous choice brings welcome readability. Ratification of the New York Conference doesn’t, of itself, waive international State immunity, aligning Australia with the USA, Canada, and (topic to the pending attraction) England and Wales.

For practitioners in cross-border dispute decision, the message is obvious: the selection of arbitral regime and the presence of an categorical waiver are issues of essential significance warranting consideration from the earliest phases of funding planning.
