Questione giuridica chiave
Whether the appeal was admissible against an incidental order requiring security for costs
Decisione estratta
The order was capable of causing irreparable harm because payment of the full security was a condition of admissibility of the appeal.
Motivazione estratta
Security orders are generally immediately appealable when non-compliance may lead to inadmissibility; here the cantonal court linked admissibility to the entire CHF 200,000, not only to the appeal-related part.
