Questão jurídica principal
Whether the cantonal judgment was rendered by a lawfully composed court
Decisão extraída
The cantonal court sat in an irregular composition because one lay judge no longer met the statutory eligibility requirements.
Fundamentação extraída
Federal courts examine ex officio the validity of first-instance proceedings. Under Art. 30(1) Cst. and Art. 6(1) ECHR, a tribunal must be established by law. Cantonal rules required the assessor to be domiciled in Geneva and politically entitled there; the judge had moved to Vaud before the judgment.
