Question juridique clé
Whether the appeal against the cantonal decision on severance was admissible despite being directed against an interim decision.
Solution extraite
The decision was an interim decision and was only appealable if it caused irreparable legal harm, which was not shown.
Motifs extraits
The alleged burden of defending two parallel criminal proceedings was merely factual, not a legal prejudice. Severance could be reconsidered later at trial and reviewed again with an appeal against the final judgment.
