Questione giuridica chiave
Whether the appeal against the cantonal decision refusing evidence taking was admissible
Decisione estratta
The appeal was inadmissible because the challenged decision was an interim procedural order on evidence and no irreparable legal harm or immediate final resolution was shown.
Motivazione estratta
Under Art. 93(1) BGG, self-standing interim decisions are only appealable if they may cause irreparable harm or if immediate admission would end the case and avoid extensive evidence proceedings. Neither condition was met; a mere evidentiary issue normally does not create irreparable legal prejudice.
