Constitutionalism and Legal Reasoning

This book, which consist of three chapters and two appendices, is intended to connect subjects that have usually been considered as detached or not strongly connected: constitutionalism, legal argumen- tion and legal ethics. Its main contention is that contemporary consti- tionalism pushes towards a new style of legal reasoning, which needs to take into account moral criteria and principles and that eventually the interpretative and moralist approach will lead to a somewhat unort- dox and less authoritarian concept of law. A constitution to be taken seriously and as a distinct and superior source of law, will end up referring to some sort of constitutional justice or judicial review. And constitutional reasoning and justice need to make recourse to principles but principles to be given an operative content should be elaborated through some form of moral reasoning. This r- soning however, if it does not want to betray the spirit of constitutional democracy and the very idea of a constitution as a special moment of self-determination, could not be just Platonism, a cognitivism without roots in the practice of public discourse and deliberation. So that cons- tutionalism will not really do without a public sphere and some activism of the latter. But if this is so, the traditional concept of law based on hi- archy, commands, prescription, sanction, and in the last instance violence, becomes obsolete. A law which is a command cannot be congruent with a practice ruled by discourse, that is, I argue, with constitution.
