Question juridique clé
Whether the beneficiary had to substantiate the guarantee call beyond the wording of the guarantee promise.
Solution extraite
No. Under Art. 111 OR and the strict formalism of on-demand guarantees, the beneficiary need only satisfy the conditions expressly stated in the guarantee text.
Motifs extraits
The court held that adding an extra substantiation duty would contradict guarantee strictness and shift the burden of defining payment conditions away from the guarantor. Only the prerequisites expressly set out in the guarantee may be demanded.
