Custody pending surrender, surrender and transit
24. Provisional custody pending surrender
1. In the event of a request from the International Criminal Court for provisional arrest, on application by the public prosecutor, the investigating judge shall order the arrest of the person sought and order provisional custody pending surrender if, on the basis of the facts of the case as reported by the International Criminal Court, there are sufficient grounds to believe that the person to be found in Austria committed a crime within the jurisdiction of the International Criminal Court which would warrant pre-trial custody (paragraph 180 of the Code of Criminal Procedure) had the crime been committed in Austria.
2. Provisional custody pending surrender may not be ordered or continued when the purposes of custody can be achieved through concurrent imprisonment, pre-trial custody or custody pending extradition. In such a case the investigating judge shall order any amendments to the custodial order which, for the purposes of provisional custody pending surrender, are essential to the International Criminal Court. In other respects provisional custody pending surrender shall be subject to the provisions of the Code of Criminal Procedure governing pre-trial custody.
