Kernrechtsfrage
Whether the refusal to hear witness F. and produce documents violated the right to be heard
Extrahierter Entscheid
No violation was shown; the cantonal court could reasonably consider the evidentiary record sufficient and refuse additional proof.
Extrahierte Begründung
Anticipated assessment of evidence is permissible when the proposed evidence is irrelevant, already clarified by the file, or unsuitable to elucidate the facts; the complaint was insufficiently reasoned and largely appellatory.
