Question juridique clé
Whether the nullity appeal was admissible against the cantonal pre-trial decision on Swiss criminal jurisdiction
Solution extraite
No. The challenged decision was an interlocutory instruction-stage ruling by an investigating authority and not a final criminal judgment; nullity appeal was unavailable.
Motifs extraits
Only judgments of the competent trial court, or in limited cases certain non-bisectable procedural decisions, are open to nullity appeal. This jurisdictional ruling remained modifiable and did not bind the future trial court.
