Understanding of the Built of European Union Legal System: The Function of Individual Rights

The article analyses whether in the EU legal system, the selection of relevant interests in horizontal legal relationships arises for the same reason and in the same way as the qualification of rights in vertical legal relationships, that is, to consolidate the EU legal system. It analyses the network of private actors and the relations among them within the EU legal order. Familiar private law instruments such as tort or contract now appear as only a small part of many possible tools harnessed with the aim of obtaining allocative efficiency or distributive justice and are synthetically described as the correction of market failures.
