Kernrechtsfrage
Whether the appellate chamber was unlawfully composed and had to be recused or treated as violating Art. 30 BV
Extrahierter Entscheid
No unlawful composition or procedural unfairness was shown; Art. 30 BV does not grant a direct right to prior notice of the panel.
Extrahierte Begründung
The appellant did not explain why the substitute judge made the panel unlawful and did not assert specific grounds for recusal. The court held that the lack of advance notice was not, by itself, constitutionally prohibited.
