Questione giuridica chiave
Whether the civil appeal sufficiently challenged the cantonal court's alternative reasoning under Art. 129 LDIP.
Decisione estratta
No. The appeal did not address the independent alternative reasoning, so the federal complaint was inadmissible.
Motivazione estratta
Where a decision rests on multiple independent grounds, each sufficient to support the result, all grounds must be contested; otherwise the appeal fails for lack of relevant reasoning.
