Kernrechtsfrage
Whether the mislabeled filing could be treated as a criminal appeal and admitted.
Extrahierter Entscheid
The filing was to be treated as a criminal appeal; no cantonal remedy was available and the appellant was entitled to appeal.
Extrahierte Begründung
The decision on pretrial detention fell under criminal matters within the meaning of the Federal Supreme Court Act, so the incorrect designation as subsidiary constitutional complaint did not harm the appellant.
