Questione giuridica chiave
Whether the cantonal decision on the interim evidence order was an appealable interlocutory decision under Art. 93 BGG.
Decisione estratta
The decision was an interlocutory decision, but no irreparable legal harm was shown; the federal appeal was therefore inadmissible.
Motivazione estratta
The alleged burdens were mainly factual and could be cured later. The appellant retained the right to be heard on any later admissible submissions, and the claim could still succeed despite production of the documents.
