Kernrechtsfrage
Whether the civil law appeal met the reasoning requirements for challenging the cantonal decision on spousal maintenance under foreign law.
Extrahierter Entscheid
The appeal did not satisfy the strict reasoning requirements because it failed to identify and argue the allegedly violated Spanish provisions and relied mainly on Swiss law.
Extrahierte Begründung
Where foreign law governs, the appellant must specifically claim and substantiate a violation of that foreign law. Mere comparison with Swiss law and appellatory criticism are insufficient.
