Questione giuridica chiave
Whether the criminal appeal against the detention refusal was admissible and timely.
Decisione estratta
The appeal was admissible: no cantonal remedy remained, the appellant was entitled to appeal, and the filing was within time.
Motivazione estratta
The cantonal appeal body had held that the detention decision was not subject to cantonal appeal, so direct federal criminal appeal was available. The renewed formal service with instructions restarted the time limit.
