Kernrechtsfrage
Whether the canton court’s finding of a causal link between the respondent’s activity and the granted construction credit was arbitrary.
Extrahierter Entscheid
No. The appellant only advanced an alternative reading of the evidence and failed to show manifestly unsustainable fact-finding.
Extrahierte Begründung
The appellate court relied on the appellant’s own 5 January 1999 letter and other evidence; it was not arbitrary to infer at least a concurrent or indirect causal role by the broker.
