Kernrechtsfrage
Whether the cantonal court arbitrarily assessed the evidence on whether continued cooperation was no longer reasonable and no important ground for termination existed.
Extrahierter Entscheid
The cantonal court's view was not arbitrary; the complaint did not show any obviously untenable evidentiary assessment.
Extrahierte Begründung
The termination letter itself indicated willingness to continue cooperation if the respondent accepted lower commissions, and the appellant's contrary assertions were either new, unsupported, or merely appellatory criticism. The complaint therefore failed to overcome the wide discretion of the trial court in weighing evidence.
