Questione giuridica chiave
Whether the appeal against the cantonal remand decision was admissible under Art. 93 Abs. 1 lit. a BGG.
Decisione estratta
The remand order did not create a sufficiently substantiated irreparable legal disadvantage; the appeal was therefore inadmissible.
Motivazione estratta
A mere remand decision is only exceptionally appealable. The prosecutor did not show why a later appeal against the final cantonal decision would not suffice, nor why interim protection before the cantonal authorities could not prevent evidentiary loss or collusion.
