Questione giuridica chiave
Whether the federal appeal was admissible against an incidental cantonal decision on conduct of the investigation and evidence-taking.
Decisione estratta
No; the challenged ruling was incidental, and the appellant did not show irreparable legal prejudice under Art. 93 LTF.
Motivazione estratta
Decisions on instruction and evidence-taking normally do not cause irreparable harm; the appellant failed to show an exception, and any complaint could be raised again later if a non-prosecution decision was issued.
