Resumen: The incorporation of human rights treaties to the constitutional block, the doctrine of conventionality control and judicial activism advocated by the Ius Constitutionale Commune for Latin America (ICCLA), seek to produce a profound transformation in the way of conceiving and operating the legal and political systems of our region, turning national and above all international judges, into the main protagonists of this process, without any control over their activity. The present work reviews this phenomenon and raises –without delving into them– several questions that arise from the theoretical consequences that the above entails.
