The public/private summa divisio iuris

Abstract

This article analyzes the old dichotomy between public and private Law, summa divisio of the juridical disciplines, where we find the other dichotomy that deals with the opening and closing of the juridical phenomena: lex and ius. Not only does a useful bipolarity arise from this fundamental classification of subject matters that jurists are dedicated to, but also the basis and juridical principles transmitted to the corresponding norms; and these basis and principles are amended by means of the supplementary technique integrating norms among different areas of the Law.
