Prisoners convicted with intentional crime can not vote. Prisoners sentenced with negligent offenses are entitled to vote. People who are sentenced with a crime but not asked to resign to a prison institution have the right to vote as well.
When were inmates granted the right to vote in prison?
Until 1995 prisoners were not entitled to vote, whether they are on trial or sentenced with a crime.
With an amendment on the Constitution, the right to vote of prisoners who are not sentenced with a final judgement was regulated. Another amendment on 2001, stipulated the right to vote for prisoners who were convicted with a crime of negligence. Final regulation was enforced after the judgement, Söyler v. Turkey, of European Court of Human Rights, on 2013. The applicant claimed that his rights protected under article 3 of the Protocol 1 to the Convention were violated since he was not allowed to vote even after he was released. The Court ruled in the favor of the applicant and within the following months Supreme Committee of Elections ruled that all released individuals and those who are sentenced with a final judgement yet not required to submit themselves to a penal institution, are entitled to vote.
