Key legal question
Whether the budget 2000 constituted a binding contractual basis for calculating the plaintiff's fee.
Extracted holding
Yes. The court upheld the finding of an actual consensus that the budget was to serve as the binding basis for remuneration.
Extracted reasoning
The cantonal court's finding rested on evidence of the defendant's own statements and the plaintiff's understanding; because an actual agreement existed, there was no room for objective interpretation under the trust principle.
