222It should be recalled at the outset that the keystone of the judicial system established by the Treaties is the preliminary ruling procedure provided for in Article 267 TFEU which, by setting up a dialogue between one court and another, specifically between the Court of Justice and the courts and tribunals of the Member States, has the object of securing uniformity in the 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 (Opinion 2/13 of 18 December 2014, EU:C:2014:2454, paragraph 176 and the case-law cited, and judgment in A.B. and Others, paragraph 90 and the case-law cited).
