Key legal question
Whether the post-termination conversion of the suspended stationär therapeutic measure into preventive detention was lawful.
Extracted holding
The conversion was lawful because the appellant was currently not treatable and the statutory requirements for preventive detention were otherwise met.
Extracted reasoning
The lower court could rely on a comprehensive expert opinion and the failed treatment attempt showed that no effective therapeutic option remained. Preventive detention is subsidiary, but permissible where a dangerous offender is not treatable and the predicate offences and reoffending risk satisfy Art. 64 StGB.
