Key legal question
Whether the cantonal court's findings on loan documents, valuation, and damage were arbitrary under Art. 9 BV.
Extracted holding
No arbitrary fact-finding was shown; the challenged evidentiary conclusions were still supportable on the record.
Extracted reasoning
The appellant did not sufficiently dispute key factual premises below, and the cantonal court could rely on the documents and later expert valuations without acting in a way that was manifestly untenable.
