Question juridique clé
Whether the Federal Supreme Court could hear the appeal against the cantonal cost order in the detention complaint proceedings.
Solution extraite
The appeal was inadmissible because the cost order in a detention complaint does not cause an irreparable legal harm within the meaning of Art. 93(1)(a) BGG, and Art. 93(1)(b) BGG did not apply.
Motifs extraits
Any challenge to the cost order remains possible together with an appeal against the final criminal decision, or later as a separate appeal if the criminal case ends in the appellant's favor. The order therefore lacks the necessary irreparable legal effect.
