Key legal question
Whether the criminal appeal against the refusal of additional evidence was admissible under Art. 93 BGG
Extracted holding
The appeal was inadmissible because the refusal of evidence in the ongoing investigation did not create an irreparable legal disadvantage.
Extracted reasoning
The court held that such a refusal can usually still be challenged later, including against a discontinuance decision or in the main proceedings. No concrete risk of irreversible loss of evidence was shown.
