Question juridique clé
Whether the complaint against the interim decision was admissible under Art. 93 BGG
Solution extraite
The prosecutor failed to show any irreparable disadvantage or other admissibility ground for a separate challenge of the interim decision.
Motifs extraits
The decision on defense participation did not end the criminal case, and the prosecutor did not address Art. 93 BGG concretely. The investigation had already been concluded by indictment and the defendant was later finally convicted, so no irreparable harm was apparent.
