Kernrechtsfrage
Whether the complaint was admissible against the substitute measure and within what scope review was possible.
Extrahierter Entscheid
The appeal was admissible in principle, but the short deprivation of liberty was not part of the dispute.
Extrahierte Begründung
The challenged decision concerned only the criminal procedural substitute measure; arguments directed solely against the brief detention fell outside the subject matter of the proceedings.
