Kernrechtsfrage
Whether the bill was forged within the meaning of Art. 182 No. 2 SchKG because the words 'Aussteller und Akzeptant' were added above the acceptance.
Extrahierter Entscheid
No. The addition was a completion of a blank bill, not a forgery of the debtor's signature; therefore no forgery opposition ground existed.
Extrahierte Begründung
Forgery is assessed from the perspective of the debtor whose liability is invoked. Here the debtor's own signature was not forged; rather, the text of an incomplete instrument was completed. Since the bill had been delivered as a blank bill and the completion remained within the authorization, there was no blank misuse either.
