Key legal question
Whether the cantonal court arbitrarily assessed the evidence and concluded that extra fees above CHF 30,000 per year were not authorized
Extracted holding
The federal court found no arbitrariness in the appraisal of evidence or establishment of facts.
Extracted reasoning
The appellant merely offered its own reading of the file. The cantonal court reasonably relied on the evidence, including testimony, and it was not shown that a formal or tacit consent to higher fees had been proved.
