Judgment_paragraph 78 · Criminal proceedings against IS (C-564/19)

78As regards, in the second place, the question whether the principle of the primacy of EU law requires the national court which has made a reference for a preliminary ruling to the Court of Justice – the unlawfulness of which has been found by the supreme court of the Member State concerned without, however, altering the legal effects of the national court’s decision to make a reference – to disregard such a decision of the supreme court, it should be noted, first, that, in accordance with the Court’s settled case-law, the principle of the primacy of EU law establishes the pre-eminence of EU law over the law of the Member States. That principle therefore requires all Member State bodies to give full effect to the various EU provisions, and the law of the Member States may not undermine the effect accorded to those various provisions in the territory of those States (judgment of 18 May 2021, Asociaţia “Forumul Judecătorilor din România” and Others, C‑83/19, C‑127/19, C‑195/19, C‑291/19, C‑355/19 and C‑397/19, EU:C:2021:393, paragraph 244 and the case-law cited).
