Juan Bautista Justo is a lawyer and teaches Administrative Law -theory and practice- at the Universidad Nacional del Comahue School of Law in the south of Argentina. Both his academic and professional interests have been focused on the area of administrative law, being this the field from which he studies the phenomenon of internationalization of law derived from the advance of human rights treaties, trying to identify the impact of this new regulatory framework in public law and, specially, in the practices of judges, legislators and public administrators. In recent years he has been working those topics with the Economic Commission for Latin America and the Caribbean (ECLAC), one of the five regional comissions of the United Nations (UN).
From the professional point of view his work has focused on litigation in defense of citizens, and has been combined with an active consulting role for different sectors of the State. Currently he works as Fiscal de Estado Adjunto in the Fiscalía de Estado of the Río Negro Province, the main body of legal advice and defense of state interests in that area.
