Nordsee case: Nordsee Deutsche Hochseefischerei GmbH v Reederei Mond Hochseefischerei Nordstern AG & Co KG is a case referred to the European Court of Justice (ECJ) by a German arbitrator by virtue of Article 267 of the Treaty on the Functioning of the European Union (formerly Article 234 of the Treaty establishing the European Community).  This article gives the "Courts or Tribunals" of Member States the power to refer matters involving the interpretation or application of European Union law to the ECJ.  It was held in this case that the ECJ could not rule on questions referred to it by an arbitrator because an arbitral body is not a court or tribunal of a Member State as defined in Article 234.
