Kernrechtsfrage
Whether the criminal appeal against the detention refusal was admissible and timely.
Extrahierter Entscheid
The appeal was admissible: no cantonal remedy remained, the appellant was entitled to appeal, and the filing was within time.
Extrahierte Begründung
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.
