Abstract. Supporters of representative democracy tend to be critical of referendums. They argue that referendums give citizens more responsibility for political decisions than they have either the capacity or the competence to take. Moreover, they argue that referendums may undermine representatives' accountability. In this article, these arguments about responsibility and accountability are analyzed in the light of normative theories of democracy, especially the theory of deliberative democracy. Furthermore, different institutional forms of referendum are analyzed. Particular attention is paid to the following aspects: the extent to which governments control the use of referendums, how referendums interact with parliamentary decision making, and whether referendums are advisory or binding. It is argued that sometimes governments indeed use their control over referendums to avoid taking stands on difficult issues. More importantly, however, current forms of government‐initiated referendums tend to weaken the accountability of the representatives, at least when interpreted in terms of liberal and deliberative democracy, and to distort parliamentary deliberations. Since delegation is a necessity in modern democracies, referendums should not undermine the mechanisms of representative democracy. In addition to the issues of citizens' capacity and competence, this viewpoint should be taken into account when designing referendum institutions.
