Kernrechtsfrage
Whether the federal criminal appeal against the cantonal decision on evidentiary requests was admissible despite being incidental.
Extrahierter Entscheid
The appeal was inadmissible because the challenged decision was incidental and could not cause irreparable legal harm.
Extrahierte Begründung
Under Art. 93 para. 1 LTF, an appeal against an incidental decision requires irreparable harm. Refusal of witness hearings at this procedural stage can be reviewed later and does not create such harm.
