Kernrechtsfrage
Whether the cantonal court arbitrarily assessed evidence by not finding that the broker had already communicated the buyers' identity on 19 March 2003.
Extrahierter Entscheid
The challenged document did not exclude that the buyers' name may have been communicated later; the finding was not arbitrary.
Extrahierte Begründung
Arbitrariness in fact-finding requires ignoring decisive evidence or adopting untenable findings. The letter relied on did not compel the conclusion asserted by the appellant.
