Questione giuridica chiave
Whether the public-law appeal against the refusal to join two criminal investigations was admissible despite being directed at an incidental decision.
Decisione estratta
The appeal was inadmissible because the challenged refusal to join proceedings was an incidental decision and no irreparable legal harm was shown.
Motivazione estratta
Under Art. 87 para. 2 OJ, incidental decisions are reviewable only if they can cause irreparable legal prejudice. The appellant's claim that non-joinder was equivalent to a refusal to investigate exculpatory evidence did not establish such harm.
