The application of the EU Charter of Fundamental Rights to the Member States has given rise both to a controversial phraseology and a controversial case-law. This paper offers a reconstruction of the constitutional intent and proposes a conceptualization in conformity with the structural function and the constitutional contemplation of the pouvoir constituent. As to the phraseological debate, it demonstrates that the Charter’s application to the Member States may occur by reason of either “implementation” or “interpretation” of EU law and the two strands are embraced but not synthetized by “scope” as a collective term. As to the substantive debate, it demonstrates that the CJEU’s case-law on “implementation” is not only amorphous but also inconsistent with the Charter’s constitutional mandate. The paper proposes a novel approach based on the notion that the application to the Member States is accessory to the supremacy of EU law. The paper’s argument is presented in the following steps. First, the paper presents the pristine rationale and constitutional function of the application to the Member State through its emergence and historical context. Second, it provides a taxonomy and critical overview of the CJEU’s amorphous case-law and presents the Court’s futile attempt to create a coherent doctrine that faithfully reproduces the constitutional contemplation behind the diagonal application and that reflects the division of competences between the EU and its Member States. Third, it sets out the proposed doctrine of “displacement.”

The EU faces one of the deepest crises since its formation. A dangerous rule of law backsliding in several Member States undermines the Union’s common values and puts Europe to the test. This raises the question of how to substantially address violations of EU values in judicial proceedings before the Court of Justice. Unfortunately, relying on fundamental freedoms, EU secondary legislation and even the Charter will not help much to resolve this value crisis. This Article takes a different path and calls for engaging with Article 2 TEU itself. Yet this proposal rests on a crucial premise: The judicial applicability of the values enshrined in Article 2 TEU. Based on recent jurisprudential developments, this Article will elaborate a framework for the operationalization of Article 2 TEU values and demonstrate how their judicial applicability can be construed. The judgments of Associação Sindical dos Juízes Portugueses, Minister for Justice and Equality (“L.M.”) and Commission v. Poland will be at the heart of this proposal.
