Kernrechtsfrage
Whether payment under the confirmed standby letter of credit was due despite the forged promissory note
Extrahierter Entscheid
The bank was not bound to pay because authenticity of the required document was a prerequisite to the credit engagement; a forged document did not satisfy the condition.
Extrahierte Begründung
Standby letters of credit are documentary and abstract, but document authenticity is essential. A beneficiary cannot rely on a forged document, even if the forgery was not immediately detectable; the bank is not meant to bear the risk of inauthentic documents.
