In Hirst v UK, the European Court of Human Rights ruled that the UK must end its blanket ban on convicted prisoners voting. In this paper I argue that the court’s reasoning undermines collective political self-determination by assuming away the essential connection between political citizenship and civil liberty in a representative democracy. I outline a democratic theory of imprisonment and argue that the democratic citizenship of imprisoned offenders is suspended not by their disenfranchisement but by their imprisonment. While many aspects of the UK’s penal practice are inconsistent with democratic self-government, the voting ban is not one of them. I conclude by outlining the numerous rights that prisoners should enjoy in a democracy
