Question juridique clé
Whether the cantonal judges had to be recused because their remarks were understood as refusing witness testimony.
Solution extraite
No recusal was required; objectively, the announcement concerned only a forthcoming procedural ruling on the evidence request, not a prejudgment of the merits.
Motifs extraits
Impartiality is assessed objectively; the misunderstanding created by the hearing wording did not amount to signs of bias or appearances of prevention.
