Kernrechtsfrage
Whether the appellant's right to be heard was violated because its managing directors were not heard personally.
Extrahierter Entscheid
No constitutional right to personal oral hearing was shown, and one director had attended evidentiary hearings; the complaint failed.
Extrahierte Begründung
Swiss constitutional law does not generally confer a right to oral statements, and the appellant did not show a procedural rule requiring personal appearance.
