State – State immunity. The defendant state of Libya's application, seeking to vary and set aside parts of an order allowing a judgment to be enforced against it, succeeded. The Commercial Court held that in proceedings to enforce an arbitration award under the Arbitration Act 1996 s 101, a document was required for instituting proceedings against a state. That document was the arbitration claim form in a case where the court required a claim form to be served, but if it did not so require, it was the order granting permission to enforce the award. In either case, the document had to be served in accordance with s 12 of the State Immunity Act 1978.
