21In that regard, it must be borne in mind that, according to the Court’s settled case-law, in the context of the cooperation between the Court and the national courts provided for in Article 267 TFEU, 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, bound to give a ruling (judgment of 20 September 2017, Andriciuc and Others, C–186/16, EU:C:2017:703, paragraph 19 and the case-law cited).
