Questione giuridica chiave
Whether the Federal Tribunal could hear the appeal despite the cantonal route under Vaud law
Decisione estratta
Because the cantonal judgment applied federal alcohol law, the federal criminal appeal was admissible.
Motivazione estratta
A judgment on appeal from a prefectural order is final only for federal-law contraventions when rendered under the relevant cantonal rule; here the decision was based on federal law, so the cantonal appeal path was not open.
