29In that regard, it must be borne in mind that, in accordance with settled case-law, in the context of the cooperation between the Court of Justice and the national courts under Article 234 EC 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 for a preliminary ruling concern the interpretation of Community law, the Court is, in principle, bound to give a ruling (see, inter alia, Case C-415/93 Bosman [1995] ECR I-4921, paragraph 59; Case C-35/99 Arduino [2002] ECR I-1529, paragraph 24; and Case C-316/04 Stichting Zuid-Hollandse Milieufederatie [2005] ECR I-9759, paragraph 29).
