This study aims to critically examine the influence of the European Union’s Charter of Fundamental Rights on the Italian constitutional adjudication system. The EU Charter’s substantive constitutional nature and the significant overlap between its guarantees and those found in the Italian Constitution will be taken into consideration as the Italian Constitutional Court highlights its most recent approaches to the Charter of Fundamental Rights. The analysis will demonstrate how, in general, the Italian Constitutional Court’s approach to the Court of Justice is one of open communication and cooperation. With reference to the so-called counter-limits doctrine, it will also highlight the critical roles that the two courts have played in defining the components of national identity and shared constitutional traditions.
