Question juridique clé
Whether the constitutional subsidiary appeal against the cantonal refusal of recusal was admissible
Solution extraite
The appeal was admissible as an immediate challenge to an incidental decision on recusal, and the subsidiary constitutional appeal was the proper avenue because no disciplinary sanction had yet been imposed.
Motifs extraits
Incidental recusal decisions are directly appealable under Art. 92 LTF. Since no sanction existed, the exception under Art. 83 let. g LTF applied, excluding ordinary appeal routes.
