The coexistence of contemporary international tribunals has fostered the access to justice for the determination of international responsibility. There are approximations and convergences between the International Law of Human Rights, International Humanitarian Law, the International Law of Refugees, and contemporary International Criminal Law. The central place is of the human person. In addressing grave violations of the rights of the human person, international tribunals have a humanist common mission of rendering justice as a form of reparation. Jusnaturalism prevails over legal positivism, conscience stands above the “will”.
