Kernrechtsfrage
Whether the appellant is entitled to the two contested brokerage commissions relating to the sale to A.________ SA.
Extrahierter Entscheid
No. The contracts of 12 June 2006 could not be interpreted as covering a commission for a sale already concluded with the A.________ group; the appellant was remunerated by the agreed flat fee for management services.
Extrahierte Begründung
The buyer was already known to the respondent, the appellant's brokerage activity predated the contract, and the trust-based interpretation of the parties' later agreements did not support a commission for the completed sale. A professional mandatary with a lump-sum fee cannot demand an increase merely because the task proved more demanding.
