Question juridique clé
Whether the appeal to the Federal Supreme Court was admissible against the cantonal decision upholding the suspension of the investigation against Y.
Solution extraite
The appeal was inadmissible because the challenged decision was an interlocutory decision and no irreparable legal harm was shown.
Motifs extraits
Under Art. 93 BGG, interlocutory decisions are appealable only if they may cause irreparable prejudice or satisfy the other statutory conditions. In criminal matters, the prejudice must be legal, not merely factual. The appellant failed to show such prejudice.
