Kernrechtsfrage
Whether the cantonal judges had to be recused after the Federal Supreme Court annulled their earlier judgment and remanded the case.
Extrahierter Entscheid
The remand for hearing defects and possible evidentiary error did not create an appearance of bias; recusal was not justified.
Extrahierte Begründung
A judge is not usually biased merely because a prior decision was overturned and the case sent back. Only particularly serious or repeated errors showing grave breach of duty can justify recusal. The grounds for remand here were insufficient.
