Questione giuridica chiave
Whether the appeal against the cantonal interim order on cost advance is admissible.
Decisione estratta
The appeal was inadmissible because the appellant did not show any irreparable legal harm or other ground allowing an exception for an interim decision.
Motivazione estratta
The challenged order was an interim decision under Art. 93 BGG. The appellant bears the burden of demonstrating the conditions for immediate appeal, and it did not do so. The Court also noted that challenges directed at the first-instance judgment could not be heard because only decisions of the last cantonal instance are appealable to the Federal Supreme Court.
