Kernrechtsfrage
Whether the cantonal court violated the appellant's right to be heard by relying on ex officio telephone inquiries without giving him an opportunity to comment.
Extrahierter Entscheid
Yes. The court relied expressly on telephone inquiries to third parties without prior opportunity for the appellant to respond, which constituted a manifest violation of the right to be heard.
Extrahierte Begründung
Under Art. 29(2) BV, parties must be allowed to comment on submissions and on evidence or information obtained by the court, including ex officio inquiries. That right was denied here and the violation could not be cured in the federal proceedings.
