Question juridique clé
Whether two cantonal judges should have been recused because they had participated in earlier judgments in the same matter.
Solution extraite
The recusal request was unfounded; prior participation as cantonal judges in earlier decisions did not, by itself, show bias or a ground for disqualification.
Motifs extraits
Intervention in the same matter 'in another capacity' is required. Simply having decided earlier adverse cases, even revision proceedings, does not establish prejudice absent objective indications of bias.
