Question juridique clé
Whether the public-law appeal against the refusal to sever criminal proceedings was admissible
Solution extraite
No; the refusal to sever was an incidental decision and did not cause irreparable legal harm.
Motifs extraits
The alleged disadvantages, such as additional work, delay, and broader participation in the proceedings, were only factual burdens. Any objections could be raised against a final cantonal decision.
