Questione giuridica chiave
Whether the public-law appeal against the interlocutory decisions was admissible without irreparable legal harm.
Decisione estratta
The challenged transmission and joinder decisions were interlocutory and caused no irreparable legal harm; the appeal was therefore inadmissible.
Motivazione estratta
A transmission order closing the preparatory investigation and forwarding the file, as well as a criminal joinder/disjoinder decision, do not end the proceedings. Any objections can be raised later before the merits court or again in later proceedings, so only legal harm incapable of later repair would justify immediate review.
