Question juridique clé
Whether X. had standing to file the criminal-law complaint before the Federal Supreme Court.
Solution extraite
No. Only a person who participated in the cantonal proceedings, or who was denied the opportunity to do so, may appeal; X. did not participate, and the assignment declaration could not create standing.
Motifs extraits
The third person, not X., took part in the proceedings before the cantonal appellate court. X. had even been excluded as representative because of the legal representation monopoly. An assignment could not remedy the missing prior participation required by Art. 81 BGG.
