46In that regard, it should be recalled that, according to the Court’s settled case-law, where the questions submitted concern the interpretation of EU law, the Court is in principle required to give a ruling. It follows that questions relating to EU law enjoy a presumption of relevance. The Court may refuse to give a ruling on a question referred by a national court only where it is quite obvious that the interpretation of EU law that is sought 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 enable it to give a useful answer to the questions submitted to it (judgment of 27 June 2017, Congregación de Escuelas Pías Provincia Betania, C‑74/16, EU:C:2017:496, paragraphs 24 and 25).
