Kernrechtsfrage
Whether the public law appeal was admissible despite the appellant's criticism effectively targeting federal law application under Art. 125 CC.
Extrahierter Entscheid
The complaint was, in substance, a federal-law challenge to the duration of spousal maintenance and was barred by the absolute subsidiarity of the public law appeal.
Extrahierte Begründung
The argument alleged a contradiction between reasons and operative part, but actually concerned the application of Art. 125 CC. The same point was raised in the connected reform appeal, so public law review was unavailable.
