Key legal question
Whether the cantonal court was validly composed when it rendered the first-instance judgment.
Extracted holding
No. One lay assessor no longer met the cantonal eligibility requirements, so the court sat in an irregular composition.
Extracted reasoning
The Federal Court reviews ex officio the regularity of the lower-instance composition. Under the constitutional guarantee of a lawful tribunal, a judge must remain eligible under cantonal law; here domicile requirements were no longer met, making the composition unlawful.
