61Under 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 provisions in the territory of those States (judgment of 6 October 2021, W.Ż. (Chamber of Extraordinary Control and Public Affairs of the Supreme Court – Appointment), C‑487/19, EU:C:2021:798, paragraph 156 and the case-law cited).
