Kernrechtsfrage
Whether the federal department had standing to appeal the cantonal detention order
Extrahierter Entscheid
The department had standing because the case concerned concrete legal questions affecting future cases, despite the respondent's release.
Extrahierte Begründung
Public-authority appeal rights under Art. 103 lit. b OG protect correct and equal application of federal law and do not require a direct interest in the individual outcome.
