A Belgian court has lifted an attachment over approximately €75.76 million in Spanish air-navigation revenues, finding that enforcing the underlying investment arbitration award would conflict with EU law. The decision represents a setback for Blasket Renewable Investments, an ICSID award creditor pursuing Spain over changes to renewable-energy subsidies. It also highlights the obstacles facing intra-EU investment award enforcement within the European Union.
What Were the Frozen Spanish Funds?
The dispute concerned payments collected by Eurocontrol, the Brussels-based organisation that administers air-navigation charges paid by airlines. Eurocontrol distributes those revenues to participating states and their service providers, including Spain’s state-owned air-navigation company, Enaire. That cross-border payment structure created an opportunity for creditors to target Spanish revenues in Belgium.
Blasket obtained an attachment order on June 17, 2025, freezing €75.76 million connected with Enaire. Spain subsequently deposited €75,759,538 on May 4, 2026, during the enforcement dispute. The amount involved in this attachment should not be confused with the total value of Spain’s outstanding arbitration liabilities.
How the Renewable-Energy Arbitration Reached Belgium
The enforcement proceedings arose from an award associated with RREEF, whose rights Blasket acquired. The underlying dispute belonged to a wider group of investment cases triggered by Spain’s overhaul of renewable-energy incentives. Investors argued that changes to the support framework damaged investments made in reliance on earlier arrangements.
Spain’s subsidy reforms, introduced more than a decade ago, generated arbitration claims involving wind and solar investments. Successful claimants subsequently sought payment through courts outside Spain, including attempts to attach assets and revenue streams abroad. The Belgian proceedings therefore concerned collection of an existing award, rather than a fresh determination of the investors’ original compensation claims.
Why the Belgian Court Lifted the Attachment
Spain challenged the attachment, supported by the European Commission. Belgium also argued that the measure breached EU law. The court ultimately lifted the freeze and ordered Blasket to pay legal costs.
The Belgian court considered enforcement contrary to EU law.

What the Decision Means for Investors and Spain
For Spain, the judgment removes a significant attachment and strengthens its position in EU enforcement litigation. For creditors, it demonstrates that obtaining an award and identifying reachable assets in the European Union may still be insufficient to secure payment when EU-law objections intervene.

The central lesson is enforcement. An investment award’s practical value depends on where creditors pursue assets and which legal constraints apply there. This Belgian outcome should not automatically be treated as resolving proceedings elsewhere: reporting identifies continuing enforcement efforts in the United Kingdom and United States, where litigation follows separate procedural paths.
Spain is a Contracting State of the Convention on the Settlement of Investment Disputes between States and Nationals of Other States (ICSID Convention) signed and ratified in 1994. Under Article 54 of the ICSID Convention, Contracting States are required to recognize and enforce awards made under the Convention.
