Questione giuridica chiave
Whether the appeal against the cantonal provisional-measures order was admissible despite the interlocutory nature of the decision.
Decisione estratta
The appeal was admissible because the refusal of evidence-preservation measures could cause irreparable legal harm.
Motivazione estratta
Injunction claims could be protected later by final judgment, but a right to evidence could be lost irreparably if proof disappeared; this satisfied Art. 93(1)(a) LTF.
