The present work has the objective of demonstrate how the instrument of popular legislative initiatives can represent the citizens participation on the construction and the maintenance of the normative ordering. Having the Habermas’ Law Discursive Theory, as the theoretical mark will serve to point a direction, emphasizing how the Fair State of law must rely on citizens, which are, at the same time, the authors and the recipients of the juridical standards. It searches to demonstrate that as much as the individuals act as authors and recipients on the construction of the law, discussing autonomously in public aspects, stronger are the possibilities of the effectuation of the democracy.
