This text explores the coordination of internal law of fundamental rights to international law of human rights; the incomprehension and difficulties that have emerged in this process and the current level of synchronization methods and purposes of both regulatory bodies. The first part points out that the Second World War, and more specifically the last quarter century has been the historical time in which they have established ties and deepening dependency through an increased harmonization of these two systems. These ties have been strengthened in Colombia through the
