Question juridique clé
Whether the criminal appeal was admissible against the cantonal interlocutory ruling on evidentiary usability.
Solution extraite
The appeal was not immediately admissible because the challenged ruling caused no irreparable legal prejudice and no lengthy or costly evidence-taking was shown.
Motifs extraits
Questions about the admissibility and use of allegedly unlawful evidence can be raised again later in the proceedings and, if necessary, on appeal against the final judgment; a mere procedural disadvantage is insufficient.
