The Statute does not specify the penalty for specific crimes, leaving it to the Trial Chamber to fix a custodial sentence to a maximum of thirty years and, ‘when justified by the extreme gravity of the crime and the individual circumstances of the convicted person’, life imprisonment. Reflecting developments in international human rights law, the Court excludes any possibility of capital punishment. It may also impose a fine. The main objectives in imposing sentence are retribution and deterrence. Aggravating and mitigating factors are set out in the Rules of Procedure and Evidence. The convicted person may apply for early release after serving two-thirds of the sentence or, in the case of life imprisonment, after twenty-five years. Sentences are served in the domestic prisons of a State Party that has been so designated by the Trial Chamber.
