From constituent fiction. Contribution to the theory of political law

Following an approach inspired by droit politique, this work aims at considering legal fiction through the unexplored prism of legitimacy in order to study from a theoretical perspective its utility in creating legal reality, i.e. in founding the law in force. Defined through its relation to political reality, constituent fiction is a technique of justification and its function is either a matter of knowledge or of government. As an instrument of knowledge, constituent fiction is at the core of the epistemology of legal positivism. It is used to relegate legitimacy, in its most political sense, to a simple matter of Sein, i.e. to an "extra legal" matter, as it is notably the case of Kelsen's Grundnorm. The first part of this work aims at showing that this isolation of law prevents a deeper understanding of its foundations. In doing so, we will try to lay the grounds for what could be an epistemology of droit politique. As an instrument of government, constituent fiction is at the core of the State. It is used to legitimize the exercise of political power by the means of representation. Relying on the classical works of Hobbes, Locke and Rousseau, the second part of this study aims at identifying the characteristics of this system of political organization that makes recourse to fiction a necessity; whatever the form of government chosen. This recourse to fiction, considered here in its broadest sense, can relate to three distinct discursive models: fiction in its strictest sense, falsehood, or myth.
