Every lawyer in Europe may legitimately wonder what EU law will look like in the years to come. The Union seems to live in a sort of interregnum: the old forms of European integration are dying, and new forms are still to be born.1 War, external threats, Europe’s dependence on external resources and infrastructures, the rule of law crisis, the ecological catastrophe, the polarization of European societies and the ensuing contestation of the Union and its law are not just ordeals to which the Union is forced to adapt. They render the law of the Union inherently unstable, requiring something new: the elaboration of a broader and more refined legal framework. (First paragraph)
