Questão jurídica principal
Whether the public-law appeal against the interlocutory decision admitting the bank as civil party was admissible under Art. 87 OJ.
Decisão extraída
No. The challenged decision was interlocutory, and the alleged disclosure of confidential information did not create an irreparable legal prejudice because the dossier had already been copied by the civil party.
Fundamentação extraída
Under Art. 87 OJ, interlocutory decisions are separately challengeable only if they can cause irreparable prejudice. Here, even a favorable ruling would not undo the fact that the bank already had access to and a copy of the file; any order to return the copy would be largely ineffective.
