A través de una decisión publicada el 30 de julio de 2021, en Antin Infrastructure Services Luxembourg S.à.r.l. y Antin Energia Termosolar B.V. v. Kingdom of Spain, el tribunal ha rechazado que existan razones para anular el laudo que había dado razón a los inversores.
257. In any event, it is clear from the Award that the Tribunal had considered and was attentive to the Parties' evidence and expert reports on damages and the value of the Claimants' lost cash flows.229 There is no reason to question therefore the Tribunal's explanation that its estimate on damages was "based on the evidence in the record and the reports of the experts".230 Further, the Tribunal's findings show that it took Spain's objections into consideration but found that "such disagreement [with the methodology of the Tribunal or its conclusions as regards the estimation of damages related to the lifetime of the plants] does not give rise to rectification under the ICSID Convention".231 Even if Spain contends that the Tribunal should have adopted a different figure, in the Committee's views, such disagreements with the Tribunal's methodology are not grounds for annulment.
258. For the above reasons, the Committee finds that there is no basis to annul the Award under Article 52(1)(e) of the ICSID Convention."
La UE por su parte ha publicado el 19 de julio de 2021, que se está investigando a fondo para valorar si pagos de España a inversores en base de laudos favorables a los posteriores cómo en el caso Antin podrían ir en contra de las reglas internas de la UE sobre subvenciones estatales.
