Questão jurídica principal
Whether a nullity appeal was admissible against the cantonal interlocutory decision on complaint standing and prescription.
Decisão extraída
Yes. The cantonal supreme criminal court had definitively decided federal-law questions decisive for the continuation of the prosecution.
Fundamentação extraída
An interlocutory decision is challengeable by nullity appeal when a last-canton-instance court finally resolves a determinative federal-law issue on which it cannot later return.
