Kernrechtsfrage
Whether the appeal against the chair's procedural order on the indictment supplement was admissible
Extrahierter Entscheid
The appeal was inadmissible because the challenged order was a non-appealable procedural order and, in any event, an intermediate decision not causing irreparable legal harm under Art. 93 BGG.
Extrahierte Begründung
The objection could still be raised at the opening of the hearing, and any consequences such as postponement could be addressed then; mere practical disadvantage is insufficient.
