Kernrechtsfrage
Whether the cantonal court violated the right to evidence by refusing further witnesses and a new expert report
Extrahierter Entscheid
No. The refusal was based on anticipatory assessment of the evidence, not on an incorrect allocation of the burden of proof.
Extrahierte Begründung
The cantonal court had already formed its conviction from the evidence on file; challenging that assessment is not a federal-law issue under Art. 8 CC.
