Article 34
General provisions
(1) The Principality of Liechtenstein may agree to enforce a sentence of imprisonment passed by the International Criminal Court or an International Tribunal, if the sentenced person:
(a) is a Liechtenstein national; or
(b) usually resides in Liechtenstein.
(2) The sentences of imprisonment passed by the International Criminal Court or International Tribunal shall be enforced directly. Sentences passed by the Court or a Tribunal may not be modified. In the light of instructions from the Court or Tribunal, enforcement shall be subject to the relevant provisions of Liechtenstein law on the understanding that the conditions of detention correspond to those of persons convicted of similar crimes in Liechtenstein.
(3) The enforcement of sentences of imprisonment passed by the International Criminal Court shall be subject to the supervision of the Court. At the request of the International Criminal Court or International Tribunal, its members shall be granted access to prisons.
(4) Should a person serving a sentence of imprisonment passed by the International Criminal Court in Liechtenstein be eligible under Liechtenstein law for more lenient treatment involving unguarded work outside the prison, the International Criminal Court shall be informed thereof before such work is allowed. Its opinion shall be taken into consideration in the decision.
(5) Sentenced persons within the meaning of this section are to be granted unimpeded and confidential written communication with the International Criminal Court or International Tribunal.
