157By virtue of the principle of the primacy of EU law, a Member State’s reliance on rules of national law, even of a constitutional order, cannot be allowed to undermine the unity and effectiveness of EU law. In accordance with well-established case-law, the effects of the principle of the primacy of EU law are binding on all the bodies of a Member State, without, inter alia, provisions of domestic law, including constitutional provisions, being able to prevent that (see, to that effect, judgment of 18 May 2021, Asociația ‘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 245 and the case-law cited).
