Kernrechtsfrage
Whether refusing to hear the seller's employee as a witness violated the right to be heard under Art. 29(2) BV.
Extrahierter Entscheid
No. The appellate court could treat the proposed testimony as not decisive and therefore decline the evidence offer.
Extrahierte Begründung
The witness was an employee of the appellant and thus not neutral; her testimony could not be relied on as the sole decisive proof for the disputed instruction about left/right orientation.
