Questione giuridica chiave
Whether the appeal against the incidental decision admitting Brazil as civil party was admissible without irreparable harm.
Decisione estratta
The appeal was inadmissible because the challenged decision was incidental and the appellant failed to show irreparable legal harm under Art. 93 LTF.
Motivazione estratta
An incidental decision can be attacked only if it may cause irreparable legal prejudice. The appellant's complaints about not being able to question Brazilian representatives did not stem from the operative part of the decision, and ordinary admission of an injured party as civil party does not normally create irreparable harm.
