Abstract : In contemporary political philosophy, the focus of the most important controversies is on the deliberative model of democracy. These controversies concern not only the theoretical problem of providing the best justification for a deliberative model of democratic legitimacy, but also the practical problem of designing the best deliberative procedure that will secure the implementation of deliberative democracy. In this paper I will present and analyze some of the most important deliberative designs: deliberative polls, citizens’ juries, consensus conferences and planning cells. I argue that these deliberative events can have a significant impact on the political behavior of a democratic community. However, I explain that all of them have only a limited influence on the policy-making activities in local and central governing structures. This is the reason why I believe we could only supplement and never fully replace the traditional aggregative procedures of democracy (voting and bargaining) with a deliberative design.
