Question juridique clé
Whether the Federal Prosecutor's appeal was properly signed by the deputy head of the legal service.
Solution extraite
Only the Federal Prosecutor himself could lodge a criminal appeal to the Federal Supreme Court in this type of notifiable case; the legal service had no authority.
Motifs extraits
Art. 81(2) BGG confers standing on the Federal Prosecutor's Office, but the applicable regulations do not extend the power to file a federal appeal to the legal service. The defect could not be cured under Art. 42(5) BGG.
