Question juridique clé
Whether the cantonal ruling setting aside the conviction and remitting the case was an appealable final decision or only an interlocutory decision.
Solution extraite
The ruling was interlocutory and did not satisfy the requirements for immediate federal appeal.
Motifs extraits
It did not terminate the proceedings, caused no irreparable prejudice because the defendant could challenge any future conviction later, and did not trigger a long and costly evidentiary procedure.
