34In accordance with the Court’s 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. Consequently, where the questions submitted concern the interpretation of EU law, the Court is in principle required to give a ruling (judgment of 23 November 2021, IS (Illegality of the order for reference), C‑564/19, EU:C:2021:949, paragraph 60 and the case-law cited).
