“Once Bingham J had given DST leave to enforce the award as a judgment, as he did in the same order as that granting the injunction, DST became judgment creditors of Rakoil, albeit subject to a suspension of their right to levy execution and subject to the possibility that the order giving them this status might be set aside on the application of Rakoil. It was not the case that DST would become judgment creditors if and when Rakoil failed to set the order aside. Once the order was made, DST were in precisely the same position as any plaintiff who has obtained judgment, subject to a stay pending an application to the Court of Appeal to set the judgment aside.”
