Question juridique clé
Whether the Bundesgericht could also review the lower cantonal prosecutor's discontinuance order
Solution extraite
Only the cantonal appellate decision could be challenged before the Federal Supreme Court; the original discontinuance order was not directly reviewable here.
Motifs extraits
A lower-court decision may be attacked only if the cantonal appellate court could not review all Federal Supreme Court grievances or did so under narrower powers, which was not shown.
