Kernrechtsfrage
Whether the factual findings of the cantonal court were arbitrary or otherwise manifestly incorrect.
Extrahierter Entscheid
The complaint did not meet the strict substantiation requirements; no arbitrariness was shown.
Extrahierte Begründung
Culpable factual error can only be reviewed if manifestly incorrect or arbitrary. The appellant merely disputed delivery of the letter and his managerial role, but the file evidence did not support a finding of arbitrariness.
