Question juridique clé
Whether the criminal-law appeal against the cantonal detention decision met the federal reasoning requirements.
Solution extraite
The appeal did not engage sufficiently with the cantonal court's reasoning and therefore could not be examined on the merits.
Motifs extraits
The appellant did not specifically address the decisive findings on urgent suspicion and repetition risk; the brief consisted largely of polemics and did not show why the upheld detention would violate federal law.
