The right to vote is one of the most fundamental, yet slowest, elements of the journey to democracy. It is the internal contradiction of civilization that it was able to reach the principle of universal suffrage so late, while so much progress has been made in every field in the world. Today, it is not difficult to explain that criteria such as wealth, ethnicity, gender – although they have been applied until recently – are outdated in terms of restricting the right to vote. However, the fact that a person sentenced to prison for committing a criminal act cannot exercise his or her right to vote is a limitation that is still in effect, even though it is based on a similar discriminatory basis, which is incompatible with the contemporary understanding of punishment. In this study, the issue of felony disenfranchisement in Turkish law has been critically analyzed by focusing the problems in legislation and practice, referring to the decisions of the European Court of Human Rights.
