Union of European Football Association and another v Euroview, [2010] All ER (D) 87 (Apr)
A national court had discretion to refer a matter to the Court of Justice as a preliminary issue where it was necessary for the resolution of the dispute before it. It was for the national court to explain why the interpretation was necessary for it to give judgment. It was generally desirable that the national court was able to define the context or procedure before it made a reference and therefore references at a preliminary stage were undesirable.
