Question juridique clé
Whether the public law appeal against the cantonal recusal decision was admissible
Solution extraite
The appeal was admissible only insofar as it sought annulment; requests to order recusal or formally declare it well-founded were inadmissible because the remedy had only cassatory effect.
Motifs extraits
The challenged decision was an incident decision on recusal rendered at last cantonal instance and could be attacked only by public law appeal, but that remedy generally allows only annulment, not substitute merits relief.
