Kernrechtsfrage
Whether the appeal against preventive detention met the Federal Tribunal's motivation requirements
Extrahierter Entscheid
The appeal was insufficiently reasoned and therefore inadmissible.
Extrahierte Begründung
The appellant merely sought annulment without showing specifically why the cantonal court's finding of a risk of reoffending was arbitrary or otherwise unlawful; this fails the qualified reasoning requirement under the LTF.
