Questão jurídica principal
Whether the cantonal court arbitrarily ignored evidence concerning termination of the brokerage mandate.
Decisão extraída
The court did not act arbitrarily; the disputed letter was considered, but it did not show when any termination occurred and could not change the outcome.
Fundamentação extraída
The complaint failed to show arbitrariness in the result. In any event, the letter only mentioned that the mandate had been withdrawn, not when. The broker’s successful steps occurred before any termination and led to the sale, so the commission claim remained unaffected.
