Kernrechtsfrage
Whether the respondent was personally liable for the full claimed amount under the mandate agreement
Extrahierter Entscheid
The respondent was not shown to be solely liable for the entire claim; she acted also as representative of her husband and the company.
Extrahierte Begründung
The Federal Supreme Court upheld the cantonal finding of the parties' actual will based on evidence; no need for trust-principle interpretation.
