The basic concept of law which was built on that of the state's sovereignty has been transformed in such a way that can be no longer recognised as operable in the reality of politics. A great number of social changes have contributed to such a transformation; such as politic and internal social pluralism, the latter contradicts the idea of sovereignty and cohesion; the establishment of alternative centres of power which coexist with the state; the institutionalisation of contexts integrate their branches of power beyond those of the State -and consequently, they are becoming unavailable both for individual States-; and for individuals to claim their rights before international jurisdictions. This paperwork analyses formal legal sources from this perspective.
