30According to the settled case-law of the Court of Justice, in the context of proceedings under Article 267 TFEU, which are based on a clear separation of functions between the national courts and the Court of Justice, any assessment of the facts in the case is a matter for the national court. The Court of Justice is thus empowered to rule on the interpretation or validity of EU-law provisions only on the basis of the facts which the national court puts before it (judgment of 21 July 2016, Argos Supply Trading, C‑4/15, EU:C:2016:580, paragraph 29 and the case-law cited).
