Questione giuridica chiave
Whether translated telephone-interception transcripts were admissible despite no record of who produced and translated them or how they were instructed.
Decisione estratta
No. The transcripts could not be used against the accused because the files did not allow verification of who created them, under what instructions, or whether the formal requirements were satisfied.
Motivazione estratta
The accused's right to be heard and to a complete case file requires that evidence production be traceable and reviewable by the parties and the court. Because the intercepted Albanian conversations were only present as typed German translations, with no indication of the persons involved or their instruction, the evidence was not sufficiently documented for adversarial scrutiny.
