23According to settled case-law, although questions on the interpretation of EU law referred by a national court in the factual and legislative context which that court is responsible for defining, and the accuracy of which is not a matter for the Court of Justice to determine, enjoy a presumption of relevance, the fact nonetheless remains that the procedure provided for in Article 267 TFEU is an instrument of cooperation between the Court of Justice and national courts, by means of which the Court provides the national courts with the points of interpretation of EU law which they require in order to resolve the disputes before them. The justification for a preliminary ruling is not that it enables advisory opinions on general or hypothetical questions to be delivered but rather that it is necessary for the effective resolution of a dispute. As is apparent from the actual wording of Article 267 TFEU, the question referred for a preliminary ruling must be ‘necessary’ to enable the referring court to ‘give judgment’ in the case before it. Furthermore, under Article 94(c) of the Rules of Procedure of the Court, the referring court must set out precisely the reasons for its uncertainty as to the interpretation of EU law (judgment of 14 May 2020, Országos Idegenrendészeti Főigazgatóság Dél-alföldi Regionális Igazgatóság, C‑924/19 PPU and C‑925/19 PPU, EU:C:2020:367, paragraphs 167 and 168).
