Questione giuridica chiave
Whether the public-law appeal against the cantonal interim decision was admissible.
Decisione estratta
The appeal was admissible under Art. 92 BGG because the decision concerned a self-standing, cantonal final interlocutory ruling on recusal.
Motivazione estratta
Recusal issues are reviewable even if the underlying step was only the filing of an authority appeal, because the challenged person participated in the proceedings in a legally relevant way.
