Kernrechtsfrage
Whether the cantonal tax court was improperly composed or biased after remittal
Extrahierter Entscheid
The challenge to the judges was inadmissible; prior participation in the earlier round did not by itself establish bias, and no other objective grounds were shown.
Extrahierte Begründung
A judge is not disqualified merely because of earlier involvement in the same matter or because the case returns after remittal. The appellants alleged no additional circumstances creating an appearance of bias. A court panel may itself decide an inadmissible recusal request.
