Question juridique clé
Whether the appellant could offset the respondent's CHF 35,000 claim with an alleged CHF 35,000 remuneration claim for services rendered
Solution extraite
No. The appellant failed to prove an executed mandate or brokerage entitlement, and the respondent could invoke non-performance.
Motifs extraits
The challenged findings that the appellant mainly acted as contractual counterparty and did not establish additional services in the respondent's favor were not shown to be arbitrary. The burden of proving performance lay with the appellant once non-performance was raised.
