Questione giuridica chiave
Whether the federal public-law appeal was admissible against the cantonal decision on exequatur of foreign inheritance judgments.
Decisione estratta
Yes; only the public-law appeal was available, and it was timely, directed against a final cantonal decision.
Motivazione estratta
Recognition and enforcement disputes over foreign judgments are not civil contests for ordinary remedies; the appeal was therefore admissible under the subsidiarity rule.
