How is an old practice of informal influence by private actors on public decision-making being discursively incorporated into normative conceptions of good governance? Based on an analysis of debates concerning lobbying regulation in France and in the Czech Republic, I try to show that three main discourses can be identified as widely used to legitimize lobbying: the discourse of normality (lobbying as a normal everyday practice), the discourse of the participation of civil society and finally, the discourses of expertise and efficiency (lobbying as an efficient source of information and expertise).
