Institutionalism and plurality of legal orders Between legitimacy and constitutional axiology

This paper addresses the issue of legal pluralism and the plurality of legal systems starting from the book ‘The legacy of pluralism. The continental jurisprudence of Santi Romano, Carl Schmitt and Costantino Mortati’. In particular, through the valuable leitmotif introduced by the Authors, consisting of the double relationship between ‘juristic and political conceptions of law’ and between ‘matter and nomic force’, the contribution of the doctrine following the publication of ‘L’ordinamento giuridico’ by Santi Romano is analysed, with particular attention to the comparison with Carl Schmitt and Costantino Mortati, focusing on the axiological innovation of the Republican Constitution.
