Specific provisions
Section 5
32. Enforcement of sentences of imprisonment
General provisions
2. The sentences of imprisonment passed by the International Criminal Court shall be enforced directly. Sentences passed by the International Criminal Court may not be modified. In the light of instructions from the International Criminal Court, enforcement shall be subject to the relevant provisions of Austrian law on the understanding that the conditions of detention correspond to those under which persons convicted of similar crimes are held in Austria.
(a) A sentence of imprisonment shall be served in a State designated by the Court from a list of States which have indicated to the Court their willingness to accept sentenced persons.
(b) At the time of declaring its willingness to accept sentenced persons, a State may attach conditions to its acceptance as agreed by the Court and in accordance with this Part.
(c) A State designated in a particular case shall promptly inform the Court whether it accepts the Court's designation.
2.
(a) The State of enforcement shall notify the Court of any circumstances, including the exercise of any conditions agreed under paragraph 1, which could materially affect the terms or extent of the imprisonment. The Court shall be given at least 45 days' notice of any such known or foreseeable circumstances. During this period, the State of enforcement shall take no action that might prejudice its obligations under article 110.
(b) Where the Court cannot agree to the circumstances referred to in subparagraph (a), it shall notify the State of enforcement and proceed in accordance with article 104, paragraph 1.
3. In exercising its discretion to make a designation under paragraph 1, the Court shall take into account the following:
(a) The principle that States Parties should share the responsibility for enforcing sentences of imprisonment, in accordance with principles of equitable distribution, as provided in the Rules of Procedure and Evidence;
(b) The application of widely accepted international treaty standards governing the treatment of prisoners;
(c) The views of the sentenced person;
(d) The nationality of the sentenced person;
(e) Such other factors regarding the circumstances of the crime or the person sentenced, or the effective enforcement of the sentence, as may be appropriate in designating the State of enforcement.
4. If no State is designated under paragraph 1, the sentence of imprisonment shall be served in a prison facility made available by the host State, in accordance with the conditions set out in the headquarters agreement referred to in article 3, paragraph 2. In such a case, the costs arising out of the enforcement of a sentence of imprisonment shall be borne by the Court.
2. The conditions of imprisonment shall be governed by the law of the State of enforcement and shall be consistent with widely accepted international treaty standards governing treatment of prisoners; in no case shall such conditions be more or less favourable than those available to prisoners convicted of similar offences in the State of enforcement.
