Despite some prominent critics, deliberative democrats tend to be optimistic about the potential of deliberative mini‐publics. However, the problem with current practices is that mini‐publics are typically used by officials on an ad hoc basis and that their policy impacts remain vague. Mini‐publics seem especially hard to integrate into representative decision making. There are a number of reasons for this, especially prevailing ideas of representation and accountability as well as the contestatory character of representative politics. This article argues that deliberative mini‐publics should be regarded as one possible way of improving the epistemic quality of representative decision making and explores different institutional designs through which deliberative mini‐publics could be better integrated into representative institutions. The article considers arrangements which institutionalise the use of mini‐publics; involve representatives in deliberations; motivate public interactions between mini‐publics and representatives; and provide opportunities to ex post scrutiny or suspensive veto powers for mini‐publics. The article analyses prospects and problems of these measures, and considers their applicability in different contexts of representative politics.
