Judgment_paragraph 34 · Irmengard Weber v Mechthilde Weber (C-438/12)

34In that regard, it should be recalled that, in accordance with settled case-law, in proceedings under Article 267 TFEU, which are based on a clear separation of functions between the national courts and the Court of Justice, the national court alone has jurisdiction to find and assess the facts in the case before it and to interpret and apply national law. Similarly, it is solely for the national court, before which the dispute has been brought and which must assume responsibility for the judicial decision to be made, to determine, in the light of the particular circumstances of the case, both the need for and the relevance of the questions that it submits to the Court. Consequently, where the questions submitted concern the interpretation of EU law, the Court is in principle bound to give a ruling (see, inter alia, Case C‑332/11 ProRail [2013] ECR, paragraph 30 and the case-law cited).
