Kernrechtsfrage
Whether the refusal to hear a witness was arbitrary under Art. 9 BV
Extrahierter Entscheid
The refusal was not arbitrary because the proposed testimony was irrelevant and the court could close evidence once further evidence was unlikely to change its view.
Extrahierte Begründung
Anticipatory assessment of evidence is permissible when the court has already formed its conviction and may reasonably assume it will not be altered by additional evidence.
