Judgment_paragraph 29 · BU v État belge (C-35/19)

29Accordingly, questions on the interpretation of EU law referred by a national court in the factual and legislative context which that court is responsible for defining, and the accuracy of which is not a matter for the Court to determine, enjoy a presumption of relevance. That presumption of relevance cannot be rebutted by the simple fact that one of the parties to the main proceedings contests certain facts, the accuracy of which is not a matter for the Court to determine and on which the delimitation of the subject matter of those proceedings depends (see, to that effect, judgment of 14 April 2016, Polkomtel, C‑397/14, EU:C:2016:256, paragraphs 37 and 38).
