Procedural Posture

This document is an approved judgment of the Court of Appeal (Civil Division) of England and Wales, addressing conjoined appeals by the Kingdom of Spain and the Republic of Zimbabwe. The appellants challenged lower High Court orders that registered adverse ICSID arbitral awards against them pursuant to the Arbitration (International Investment Disputes) Act 1966.

Principal Legal Issues

The central legal question is whether foreign states can invoke state immunity under the State Immunity Act 1978 (SIA) to set aside the registration of ICSID awards in the United Kingdom. The Court examined whether Section 1(1) of the SIA applies to the registration of ICSID awards and, if so, whether Article 54 of the ICSID Convention constitutes a prior written agreement by the states to submit to the jurisdiction of the UK courts, thereby engaging the exception to immunity under Section 2(2) of the SIA.

Parties' Positions

Spain and Zimbabwe contended that the SIA grants them general immunity from the adjudicative jurisdiction of the UK courts, which encompasses the registration of arbitral awards. They further argued that Article 54 of the ICSID Convention does not amount to an express waiver of immunity or a submission to jurisdiction. Conversely, the claimants asserted that the registration of an ICSID award is a ministerial act to which state immunity does not apply. In the alternative, the claimants argued that the states had submitted to the jurisdiction through the ICSID Convention or their respective arbitration agreements, engaging the exceptions in Sections 2 and 9 of the SIA.

Court's Analysis and Findings

The Court of Appeal held that the registration of an ICSID award is an adjudicative act that inherently engages the general immunity provided by Section 1(1) of the SIA. However, the Court determined that by ratifying the ICSID Convention, Contracting States expressly submit to the jurisdiction of the courts of other Contracting States for the recognition and enforcement of awards under Article 54. The Court grounded its reasoning in the ordinary meaning of Article 54, the object and purpose of the Convention, and the travaux préparatoires. The Court also placed significant weight on international jurisprudence, particularly the High Court of Australia's analogous decision enforcing the same award against Spain. Consequently, the Court found that the exception to state immunity under Section 2(2) of the SIA was firmly engaged, precluding the states from opposing registration on immunity grounds.

Decision

The Court of Appeal dismissed both appeals concerning the state immunity challenges. However, the Court remitted Zimbabwe's application to set aside the registration to the Commercial Court for further directions to adjudicate its alternative, non-immunity defences.
