Question juridique clé
Whether the federal appeal against the cantonal decision was admissible despite its incidental nature
Solution extraite
The appeal was inadmissible because the appellant showed neither irreparable harm nor the conditions for an immediately final decision under Art. 93(1) LTF.
Motifs extraits
The challenged decision did not end the criminal proceedings. If the appeal were allowed, the case would still have to be remitted to the cantonal complaint authority for a decision on the merits, so Art. 93(1)(b) LTF was not met.
