Kernrechtsfrage
Whether the Obergericht was competent to extend security detention in the pending post-trial measure proceedings.
Extrahierter Entscheid
Yes. The appellate court acting as the seized court could decide the detention issue; no separate lower-court review was required.
Extrahierte Begründung
Under Art. 59 para. 4 StGB and Arts. 363-365 StPO, the court handling the post-trial measure decision may also decide related procedural detention matters. Canton Lucerne assigned such decisions to the Obergericht.
