Questão jurídica principal
Whether the broker was entitled to a commission under Art. 413 CO despite the sale being concluded with a third party rather than the person initially introduced.
Decisão extraída
The broker did not establish the required psychological causal link between its activity and the conclusion of the sale, so no commission was due.
Fundamentação extraída
When the contract is concluded with a third party, causation is generally absent unless the introduced person and the final buyer are so closely connected that they can be treated as one. Here, the cantonal findings did not show such a relationship, and the broker’s activity was limited to introducing a first interested party and later passing on the vendor’s phone number.
