Questione giuridica chiave
Whether the appeal remained admissible after the appellant's release and partial acquittal
Decisione estratta
The appeal remained admissible because the appellant retained a current interest in a finding that the detention had been unlawful under Art. 431 CPP.
Motivazione estratta
A claim for costs alone is insufficient, but a declaration of unlawfulness of coercive detention justifies review even after release; substitution by security detention does not change the substantive detention criteria.
