The Court of Appeals affirmed on the same grounds the decision of the District Court (US 995), which had rejected the petitioner’s motion to vacate an arbitral award rendered in the United Kingdom, ruling that it lacked jurisdiction under the 1958 New York Convention, pursuant to which only the courts of the country where or under whose law the award was rendered had primary jurisdiction to vacate the award. As a court of secondary jurisdiction, the US court could only grant or refuse recognition and enforcement under the Convention.
