Imagine spending years, even decades, fighting for justice in an international dispute, finally winning a substantial arbitration award, only to discover you can't simply transfer that victory to another party. That's the harsh reality revealed in a recent English court ruling that's sending shockwaves through the world of international arbitration.
On November 10, 2025, the English Commercial Court delivered a landmark judgment stating that arbitration awards issued under the International Centre for Settlement of Investment Disputes (ICSID) Convention and the Energy Charter Treaty (ECT) cannot be assigned. This means that if you win an award under these frameworks, you generally can't sell it, gift it, or transfer it to someone else.
Why is this such a big deal? Well, consider scenarios like corporate reorganizations where assets are routinely transferred between subsidiaries, or situations where a company needs to raise capital by selling its assets, including pending or realized arbitration awards. This ruling potentially throws a wrench into those plans when ICSID or ECT awards are involved. It could prevent a new owner, for instance, a related company after restructuring, or even a third-party investor who bought the award, from directly enforcing it in England and Wales. This significantly impacts the liquidity and value of these awards.
Let's delve into the specifics of the case: Operafund Eco-Invest SICAV Plc v The Kingdom of Spain [2025] EWHC 2874 (Comm). Between 2008 and 2009, Operafund Eco-Invest SICAV Plc and Schwab Holding AG invested heavily in Spanish solar energy plants. They claim they did so based on Spain's promises of attractive minimum tariffs and incentives for renewable energy projects. However, Spain later changed the rules, allegedly breaching the ECT by revoking those incentives.
The investors initiated arbitration against Spain in 2015 under the ICSID Convention, leveraging Article 26 of the ECT. In 2019, they won an award of EUR 29.3 million. The award was then registered in England & Wales in 2021, effectively giving it the same legal standing as a High Court judgment for enforcement purposes.
Spain tried to overturn the order registering the award, citing state immunity, but that issue is currently on hold, awaiting a decision from the UK Supreme Court in a similar case (Infrastructure Services Luxembourg S.à r.l. v The Kingdom of Spain [2024] EWCA Civ 1257).
And this is the part most people miss... In 2024, the investors attempted to assign their rights to the award to Blasket Renewable Investments LLC. They then applied to substitute Blasket as the claimant in the ongoing proceedings. Spain objected, arguing that the award wasn't assignable under international law. This is where the English Commercial Court stepped in.
The Court's decision was multifaceted:
- First, it found that there's no established rule in customary international law that either allows or prohibits the assignment of ICSID awards.
- However, upon examining the ICSID Convention itself, the Court concluded that ICSID awards are not assignable. The Court emphasized the unique nature of the ICSID system and the importance of maintaining its integrity.
- Furthermore, even if other ICSID awards could be assigned, the Court ruled that awards related to ECT claims specifically are not assignable based on the treaty's construction. This determination highlights the specific wording and intent behind the ECT, creating a potential distinction even within the ICSID framework.
- Finally, any rights the original claimants gained through the registration order were also deemed non-assignable, consistent with the core finding.
But here's where it gets controversial... The court's interpretation hinges on the intent of the ICSID Convention and the ECT. Some legal scholars argue that prohibiting assignment restricts the free flow of capital and potentially harms investors, especially smaller ones who might need to liquidate their assets. Others contend that allowing assignment could open the door to speculative trading in arbitration awards, potentially undermining the integrity of the arbitration process and leading to abusive practices.
This judgment could have far-reaching implications. While the decision is currently subject to potential appeals to the Court of Appeal and ultimately the UK Supreme Court, it immediately raises questions. For example, does this ruling apply only to enforcement in England and Wales, or could it influence courts in other jurisdictions? How will this affect future investment decisions related to countries that are signatories to the ICSID Convention and the ECT? Could this lead to a re-evaluation of how these treaties are drafted and interpreted?
