Kernrechtsfrage
Whether the guarantee contract was validly concluded and could be relied on in valuing the pledged assets.
Extrahierter Entscheid
The guarantee agreement was validly concluded; the appellant failed to show otherwise with admissible, substantiated arguments.
Extrahierte Begründung
The lower court reasonably found that the documents were signed, dated, and stamped, that the respondent accepted the guarantee request in time, and that the appellant did not adequately challenge these independent grounds.
