Kernrechtsfrage
Whether refusal to order a voice analysis violated the right to be heard.
Extrahierter Entscheid
No violation was shown; the court could refuse further evidence because it could already assess the matter without arbitrariness.
Extrahierte Begründung
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.
