E. Enforcement of sentences of imprisonment in Liechtenstein
Article 35
Procedure for acceptance of enforcement of sentence
(4) Should the sentenced person escape from prison before the expiry of the sentence, the princely court (Article 38 of the law on enforcement of sentences) shall issue a warrant of arrest and initiate a search. Should the person sought subsequently be arrested abroad, the princely court shall, even without an application from the public prosecutor, seek extradition custody pursuant to Article 69 of the law on judicial assistance and transmit the documents required under Article 68 of the said law to the Ministry of Justice. The Ministry of Justice shall seek extradition if the requested State does not approve surrender without an extradition procedure, and the International Criminal Court or International Tribunal has not decided otherwise.
(5) The time spent in custody in the requested State or at the International Criminal Court or International Tribunal shall be deducted from the sentence to be served.
(6) Should persons who have escaped while serving a sentence passed by the International Criminal Court or International Tribunal be arrested in Liechtenstein, they shall be surrendered to the State ensuring the enforcement of their sentence according to the provisions which apply for the surrender of persons to the International Criminal Court or International Tribunal.
