Key legal question
Whether the federal nullity appeal was admissible against the cantonal judgment rendered under Art. 346 ch. 5 CPP/JU.
Extracted holding
No. Because the cantonal court's review of federal law was limited to arbitrariness, the federal nullity appeal was unavailable.
Extracted reasoning
Art. 268 ch. 1 PPF permits a federal nullity appeal only against cantonal judgments not subject to a cantonal remedy allowing free review of federal law. Where the cantonal higher court has only limited cognizance, only the lower-court judgment may be attacked, unless that court is itself a tribunal inferior within the meaning of the statute.
