Kernrechtsfrage
Whether the public-law appeal alleging arbitrariness in the cantonal court's interpretation of Spanish gift law should be admitted.
Extrahierter Entscheid
The appeal was admissible only insofar as it challenged the alleged arbitrary application of Spanish civil law; otherwise, the public-law route was limited by the subsidiarity rule.
Extrahierte Begründung
In pecuniary civil disputes, erroneous application of foreign law could not be challenged by appeal in reform or nullity, so the public-law appeal was the available remedy for arbitrariness.
