Kernrechtsfrage
Whether refusing to hear witness E. was arbitrary or violated the right to be heard.
Extrahierter Entscheid
The refusal was not arbitrary because E. had not witnessed the incident and was not neutral.
Extrahierte Begründung
The court accepted the lower court's double reasoning: a non-eyewitness could not provide relevant evidence, and the witness lacked neutrality due to a conflict with B. Y.
