Questione giuridica chiave
Whether the subsidiary constitutional appeal was admissible against the cantonal interlocutory decision on recusal.
Decisione estratta
The appeal was in principle admissible because the decision on recusal was interlocutory and no further appeal lay; the court did not need to decide whether an ordinary civil appeal might also have been available.
Motivazione estratta
Interlocutory recusal decisions are challengeable only through the same route as the final decision. The appellants relied only on constitutional rights, and the appeal was timely.
