Questione giuridica chiave
Whether the documents filed proved that the Italian judgment was enforceable in the state of origin under Art. 47(1) LugÜ.
Decisione estratta
No; a mere deposit notice was insufficient because the required formal certificate of security performance was not shown.
Motivazione estratta
The Federal Court held that the source-state law governs which documents prove enforceability, and the cantonal court could reasonably interpret the Italian provisions as requiring a formal certificate confirming that security had actually been duly performed.
