Key legal question
Whether the federal criminal appeal against the cantonal inadmissibility decision was admissible
Extracted holding
The appeal was admissible only in principle, because the cantonal decision was final and ended the criminal proceedings; the appellant could challenge procedural rights and the refusal to enter into the merits.
Extracted reasoning
The Court examined admissibility ex officio and held that the cantonal ruling was a final criminal decision. However, review was limited by the requirement to challenge the formal inadmissibility reasoning specifically.
