Questão jurídica principal
Whether the civil appeal sufficiently challenged the cantonal court's alternative reasoning under Art. 129 LDIP.
Decisão extraída
No. The appeal did not address the independent alternative reasoning, so the federal complaint was inadmissible.
Fundamentação extraída
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.
