Abstract
A frayed theoretical discussion has been taking place in most Common Market countries since the mid-1970s, and it has been followed by large-scale empirical research. These studies demonstrate the unforeseen importance of socio-political formations which cannot be comprehended by frameworks based on constitutional law and its understanding of a sound political order. On the contrary, standard constitutional accounts often treat these formations as relics of pre-modern regimes. In fact, however, corporatist arrangements envision socio-political controls not anticipated by the constitutional state. There is an unofficial interaction between associations and interest groups on the one hand, and the government and parties on the other. This has important ramifications for political theory and especially for the conceptualization of democracy
