Kernrechtsfrage
Admissibility of the public-law appeal against the cantonal ruling on recusal
Extrahierter Entscheid
The appeal was admissible because the cantonal ruling was a separately issued final interlocutory decision on a recusal request within the meaning of Art. 92 BGG.
Extrahierte Begründung
A recusal decision is separately appealable even when the underlying act is an authority's appeal against a permit; the chair's participation through filing the appeal was sufficient.
