Questione giuridica chiave
Whether the public law appeal against the joinder order was admissible despite its incidental nature.
Decisione estratta
The appeal was inadmissible because the joinder order was an incidental decision that did not cause irreparable legal harm within the meaning of Art. 87 OG.
Motivazione estratta
The alleged disadvantages were merely factual, such as longer proceedings, higher costs, and the publicity of a single trial. Such effects do not amount to irreparable legal prejudice, and the complaint about the parties' access to information in a public hearing was insufficient.
