ABSTRACT – Starting with an examination of the digital and artificial intelligence tools used by the Court of Justice of the European Union, this Blog analyzes the ways in which the European institution ensures respect for personal data during the exercise of its judicial activity. The contribution focuses, in particular, on the difficulty of defining the boundary between activities that fall within the scope of judicial activities and those that do not, as well as on the relationship between the administrative-type protection provided by the Court and that of a judicial nature.
