Résumé : Conceived as an alternative form of democratic representation, the random selection of citizens for a political task comes in tension with the logic of electoral representation. The idea, carried by random selection, that anyone can be a good enough representative challenges the assumption that we need to choose the most competent among ourselves. And the fact that citizens’ assemblies are sometimes tasked to draft legislation may undermine the authority of elected representatives. This article tests this hypothesis of tension between competing forms of representation on a recent case: the French Citizen Convention for Climate (CCC) in 2020. Drawing on parliamentary hearings and questions as well as public political reactions to the CCC, we find indications that elected representatives may feel threatened in their legitimacy even when most randomly selected citizens do not see themselves as representatives. This may be due to the fact that the CCC was seen by some as stepping on the prerogatives of the Parliament. This suggests that future experiments of the sort could benefit from a clearer functional division between the two forms of representation.
