23In that connection, it must be borne in mind that, according to settled case-law, 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, which enjoy a presumption of relevance. If, therefore, the question referred concerns the interpretation or validity of a rule of EU law, the Court is, in principle, required to give a ruling, unless it is quite obvious that the interpretation sought bears no relation to the actual facts of the main action or to its purposes or where the problem is hypothetical or the Court does not have before it the factual or legal material necessary to give a useful answer to the question submitted to it (see, to that effect, judgments of 15 December 1995, Bosman, C‑415/93, EU:C:1995:463, paragraph 61; of 7 September 1999, Beck and Bergdorf, C‑355/97, EU:C:1999:391, paragraph 22; and of 5 May 2022, Zagrebačka banka, C‑567/20, EU:C:2022:352, paragraph 43 and the case-law cited).
