Kernrechtsfrage
Whether the criminal appeal against the interlocutory referral order was admissible under Art. 93 BGG.
Extrahierter Entscheid
The appeal was not admissible because the challenged referral order caused no irreparable legal harm.
Extrahierte Begründung
A referral order after completion of the investigation does not ordinarily create irreparable legal prejudice; the requested evidentiary complaint could still be raised later.
