Question juridique clé
Whether the federal appeal against continued pre-trial detention was admissible
Solution extraite
The appeal was admissible because the cantonal decision was a final cantonal criminal matter, the detention order was an independently appealable interim decision causing irreparable harm, and the appellant had standing.
Motifs extraits
Continued detention creates a non-remediable disadvantage; the Federal Supreme Court could decide the matter directly if the appeal were upheld.
