Arbitration analysis: In a judgment dated 12 April 2023, the Australian High Court has dismissed the appeal lodged by the Kingdom of Spain (‘Spain’) and upheld the recognition and enforcement of the €101m ICSID award favourable to renewable energy investor Infrastructure Services Luxembourg S.À.R.L. (‘Respondent’). The court considered that Spain had effectively waived its regime of sovereign immunity from the Australian jurisdiction under Part II of the Foreign States Immunities Act 1985 (‘FSIA’). However, immunity from jurisdiction to execute the award, a crucial and distinct concept from ‘recognition’ and ‘enforcement’ included in Part IV of the FSIA, remains intact for Spain, representing a significant setback against the Respondent. By interpreting the Convention on the Settlement of Investment Disputes between States and Nationals of Other States (‘ICSID Convention’), the High Court of Australia concluded that ‘recognition’ refers to a binding requirement to recognise an award before the domestic courts, while ‘enforcement’ relates to the financial obligations imposed by the arbitral award to be enforced as if it was a final judgment issued by a domestic court. These two concepts sensibly differs from ‘execution’, which refers to how a judgment enforcing an international arbitral award is given effect, commonly through specific measures against the executed party’s assets within the court’s domestic jurisdiction. However, although Spain had effectively waived its immunity against ‘enforcement’ and ‘recognition’, immunity from ‘execution’ still protects Spain from the practical executive actions against its assets in the Australian jurisdiction. Therefore, although the judgment of the High Court rejected the Spanish appeal confirming the lower courts decisions, it only concerned the recognition and enforcement of the ICSID award, not its execution, to the despair of the Respondent, who will no doubt not be so interested in terminological discussions but in the actual award payment.
