The Court of Justice of the European Union has for decades relatively successfully negotiated its way under circumstances which the theory of constitutional pluralism adequately portrays. In part, this achievement is due to the Court's warranted minimalist approach to adjudication, its way of legal reasoning in interpreting EU law, and the techniques with which it reserves space for communication, interaction, and even conflict between legal orders. Building on existing accounts of both the Court's practice and constitutional pluralism, this chapter concentrates on the prerequisite that the members of the community of judicial discourse understand the Court's established patterns of legal interpretation and reasoning, as well as their role in maintaining the pluralist European legal order.
