Questione giuridica chiave
Whether the cantonal court arbitrarily refused to find manifest abuse of rights in the beneficiary's call on the guarantee beyond USD 60,122.
Decisione estratta
The cantonal court's refusal was arbitrary insofar as it allowed payment above USD 60,122; the documents showed the residual debt had been fixed at that amount.
Motivazione estratta
The June 16, 2002 acknowledgment and annexed table clearly established a remaining balance of USD 60,122. Calling a guarantee for USD 300,000 when only that residue could still be owed was manifestly abusive.
