18In that regard, it is necessary to state at the outset that, in accordance with settled case-law, in proceedings under 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 and the relevance of the questions which it submits to the Court. Consequently, where questions submitted concern the interpretation of EU law, the Court is bound, in principle, to give a ruling (judgment of 26 January 2017, Banco Primus, C‑421/14, EU:C:2017:60, paragraph 29 and the case-law cited).
