Kernrechtsfrage
Whether a single judge was competent to decide the remanded costs issue
Extrahierter Entscheid
The single judge could decide the costs question; the complaint did not show arbitrary application of cantonal procedure and this was compatible with the Constitution.
Extrahierte Begründung
For a mere cost decision after remand, it was not self-evident that a panel of three judges was required; the appellant failed to substantiate arbitrariness under cantonal law.
