Kernrechtsfrage
Whether the appeal against the severance order was admissible under Art. 93 LTF.
Extrahierter Entscheid
The appeal was inadmissible because the challenged decision was interlocutory and the appellant did not show irreparable legal harm.
Extrahierte Begründung
The severance order did not end the criminal proceedings. It was not a decision under Art. 92 LTF, and no immediate final decision or irreparable legal prejudice was demonstrated. The appellant remained able to request joinder and postponement of the hearing later under the CPC.
