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 of 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 (judgments of 6 September 2016, Petruhhin, C‑182/15, EU:C:2016:630, paragraph 19, and of 8 December 2016, Eurosaneamientos and Others, C‑532/15 and C‑538/15, EU:C:2016:932, paragraph 27).
