The European legal space does not know one European model of constitutional adjudication. Rather, it embraces almost all possible institutional set-ups of constitutional adjudication. According to Article 4(2) TEU, the equality of the Member States’ constitutional orders comprehends the plurality of mechanisms that protect the constitution’s normativity. These institutional and procedural divergences clearly impact on the dialogue between each constitutional court and the European courts. To understand the dynamics of these dialogues, legal scholarship has to consider the specific features of each system of constitutional adjudication and the context in which it operates.
