Key legal question
Whether the cantonal judgment was arbitrary in its factual findings and evidence assessment under Art. 9 BV.
Extracted holding
The complaint did not show arbitrariness; the challenged findings were either consistent with the record or irrelevant to the liability assessment.
Extracted reasoning
The federal court found no manifest contradiction or untenable reasoning. The appellant mixed up the exhibition's organization with the stunt show's organization and failed to substantiate his objections.
