Abstract : The judiciary can be understood as a symbolic system composed of rites, architecture, suits ... which are deep rooted in the divine. This symbolic system ensures the authority of the judicial institution and of its discourse: a dogmatic discourse. The passage from tradition to modernity and post modernity characterized by the dominance of the principle of reason may weaken the discourse of the judicial institution. Because of its rationalization, it is now competing against other kinds of discourse and especially those of politicians. Just like other social institutions, the judicial institution is particularly confronted with the post modern problems of the meaning and representation.
