Question juridique clé
Whether the appeal was admissible insofar as X. sought joinder of the proceedings against all three persons, including his own prosecution status.
Solution extraite
That part did not concern a final or otherwise appealable decision and could not be heard.
Motifs extraits
The request could be read as also attacking X.'s own indictment status, but no appealable decision existed in that respect under the Federal Supreme Court Act.
