Questione giuridica chiave
Whether the public law appeal sufficiently challenged the cantonal court's findings on mortgage interest charges after separation.
Decisione estratta
The complaint failed because the appellant misunderstood that she was charged only with post-separation mortgage interest, not with charges incurred during the cohabitation period.
Motivazione estratta
The arbitral award applied society rules during cohabitation but co-ownership rules after separation; the challenged amount concerned only the latter period.
