Questione giuridica chiave
Whether the telephone surveillance transcripts were admissible despite challenges to traceability, disclosure, and interpreter instructions.
Decisione estratta
The surveillance records were sufficiently traceable and documented; the interpreter was properly identified and warned, and the transcripts could therefore be used as evidence.
Motivazione estratta
The court held that the files contained the essential data and recordings, the persons involved in transcription and translation were identifiable, the interpreter's warning under Art. 307 StGB was established, and the reconstruction of the surveillance process met constitutional fairness and access-to-file requirements.
