TITLE II
Extradition from Austria

Chapter ONE
Admissibility of Extradition

Punishable Acts Qualifying for Extradition
§ 11. (1) Extradition shall be admissible for the prosecution of intentionally committed acts that are punishable under the law of the requesting State by a custodial sentence of more than one year or by a preventive measure of the same duration and that are subject to a custodial sentence of more than one year under Austrian law. The penal sanctions, as amended by § 5 item 4 of the 1988 Juvenile Court Act shall not be used as a basis for deciding whether a punishable act shall give rise to an extradition. It is irrelevant whether an application, as required for prosecution under Austrian law, has been made or such an authorization has been given.
