Questão jurídica principal
Whether the cantonal court was regularly composed and satisfied the right to a lawful judge.
Decisão extraída
The challenge fails: under cantonal law the composition with two cantonal judges and a tribunal president was lawful, and no objective doubts as to independence or impartiality were shown.
Fundamentação extraída
The relevant cantonal provision allowed such a mixed composition, and the appellant did not show arbitrariness or a concrete appearance of bias.
