72On this point it must be borne in mind that it is solely for the national court before which the dispute has been brought, and which must assume responsibility for the subsequent judicial decision, to determine in the light of the particular circumstances of the case both the need for a preliminary ruling in order to enable it to deliver judgment and the relevance of the questions which it submits to the Court. Consequently, where the questions submitted by the national court concern the interpretation of Community law, the Court of Justice is, in principle, bound to give a ruling. The Court may refuse to rule on a question referred for a preliminary ruling by a national court only where it is quite obvious that the interpretation of, or assessment of the validity of, a provision of Community law that is sought by the court making the reference bears no relation to the actual facts of the main action or its purpose, where the problem is hypothetical, or where the Court does not have before it the factual or legal material necessary to give a useful answer to the questions submitted to it (see, inter alia, Case C-415/93 Bosman [1995] ECR I-4921, paragraphs 59 to 61, Case C-36/99 Idéal tourisme [2000] ECR I-6049, paragraph 20, and Case C-137/00 Milk Marque and National Farmers' Union [2003] ECR I-7975, paragraph 37).
