Questione giuridica chiave
Whether the appeal against the cantonal court's remand decision was admissible as an independent appeal
Decisione estratta
The remand decision was an appealable interim decision only if Art. 93 BGG was met; neither irreparable harm nor significant savings in time or cost was shown.
Motivazione estratta
The opponents could challenge a later adverse decision again, and the asserted cost risk did not constitute irreparable harm. A large evidentiary procedure had already taken place, so no major additional effort would be saved.
