Questione giuridica chiave
Whether refusal to order a voice analysis violated the right to be heard.
Decisione estratta
No violation was shown; the court could refuse further evidence because it could already assess the matter without arbitrariness.
Motivazione estratta
The relevant calls had been played to the defendant, no prior timely request had been made, voice analysis was considered unsuitable and lacked reliable comparison material, and the existing evidence already allowed attribution.
