Involving people in policy-making is generally a good thing. Policy-makers themselves often pay at least lip-service to the importance of giving citizens a say. In the academic literature, participatory governance has been, with some exaggeration, almost universally hailed as a panacea to all ills in Western democracies. With this article, we want to inject a dose of healthy scepticism into the debate or, more precisely, to show that there are circumstances in which public consultations will achieve anything but greater legitimacy and better policy-outcomes. We do this partly by discussing the more questionable assumptions in the participatory governance literature, and partly by examining a recent, glaring example of the misuse, and abuse, of popular input: Viktor Orban’s national consultations in Hungary. We also propose five requirements to help deciding when consultations might be appropriate: posing questions that allow for citizens’ autonomous choice; strong procedural guarantees to ensure a balanced debate and verifiable outcomes; the result to at least have the potential to settle actual policy; cost-effectiveness; and political communication that is truthful about the aims and consequences of the vote.
