Questione giuridica chiave
Whether the translated telephone-interception transcripts were usable as evidence despite no record of who produced and translated them or how they were instructed.
Decisione estratta
The transcripts could not be used against the accused because the files did not make their production traceable for the court or the defence.
Motivazione estratta
Even if cantonal law did not expressly regulate wiretap transcripts, constitutional hearing rights require evidence production to be understandable and verifiable. Here the records did not show who prepared the German translations, whether the persons were warned under Art. 307 StGB, or how the translations were made.
