Questione giuridica chiave
Whether the reformation appeal was admissible despite challenging only one of two independent cantonal grounds
Decisione estratta
No. Because the cantonal decision rested on two independent reasons and the appeal attacked only one of them, the Federal Court could not enter into the merits.
Motivazione estratta
When a cantonal judgment is based on two independent grounds, both must be challenged; otherwise the judgment stands on the unchallenged ground alone.
