Kernrechtsfrage
Whether the appeal against the interlocutory severance order was admissible under Art. 93 LTF.
Extrahierter Entscheid
The appeal was inadmissible because the appellant did not show irreparable legal harm, and such harm was not obvious.
Extrahierte Begründung
A severance order is an interlocutory decision. The appellant failed to allege and prove irreparable legal prejudice. He could later request joinder at trial and, if necessary, challenge the severance in an appeal against a final judgment.
