254In that context, it must be made clear that, in accordance with Article 19 TEU, whilst it is for the national courts and tribunals and the Court to ensure the full application of EU law in all the Member States and to ensure effective judicial protection of the rights of individuals under that law, the Court has exclusive jurisdiction to give the definitive interpretation of that law (see, to that effect, judgment of 2 September 2021, Republic of Moldova, C‑741/19, EU:C:2021:655, paragraph 45). In addition, in the exercise of that jurisdiction, it is ultimately for the Court to clarify the scope of the principle of the primacy of EU law in the light of the relevant provisions of that law; that scope cannot turn on the interpretation of provisions of national law or on the interpretation of provisions of EU law by a national court which is at odds with that of the Court. To that end, the preliminary-ruling procedure provided for in Article 267 TFEU, which is the keystone of the judicial system established by the Treaties, sets up a dialogue between one court and another, specifically between the Court of Justice and the courts of the Member States, having the object of securing the uniform interpretation of EU law, thereby serving to ensure its consistency, its full effect and its autonomy as well as, ultimately, the particular nature of the law established by the Treaties (judgments of 6 March 2018, Achmea, C‑284/16, EU:C:2018:158, paragraph 37 and the case-law cited, and of 6 October 2021, Consorzio Italian Management and Catania Multiservizi, C‑561/19, EU:C:2021:799, paragraph 27).
