Questão jurídica principal
Whether the appeal was admissible against the cantonal decision refusing additional evidence in an ongoing criminal investigation
Decisão extraída
The decision was interlocutory, not final, and no irreparable legal prejudice was shown; the appeal was therefore inadmissible.
Fundamentação extraída
The refusal of evidence during investigation is only a procedural step toward a final decision. The appellant did not explain any irreparable legal harm, since the evidentiary objections could be raised again against the final judgment. Economy-of-proceedings grounds did not apply.
