Questione giuridica chiave
Whether the use of telephone surveillance transcripts violated constitutional rights and made the evidence unusable.
Decisione estratta
The transcripts were sufficiently documented and traceable; the defence had access and could challenge them, so their use was not unconstitutional or arbitrary.
Motivazione estratta
The court held that the production of the evidence and the identity of those who prepared and translated it were sufficiently ascertainable from the file and hearing; no formal written 'evaluation order' was required as a validity condition.
