Question juridique clé
Whether the cantonal court was composed lawfully despite a judge who had left office before the judgment date.
Solution extraite
No. A panel including a judge whose mandate had already ended was not a tribunal established by law.
Motifs extraits
Article 30(1) of the Constitution and Article 6(1) ECHR require a tribunal composed according to law. A judge cannot participate after the end of office; such a defect is fundamental and cannot be cured by party consent.
