Questão jurídica principal
Whether telephone interviews of foreign-resident witnesses and victims were procedurally usable.
Decisão extraída
The telephone interviews were not provided for under the applicable Zurich criminal procedure rules and were therefore invalid and unusable against the defendant.
Fundamentação extraída
Section 14 para. 1 sentence 2 aStPO/ZH concerned foreign evidentiary hearings under mutual legal assistance, not telephone questioning by Zurich authorities. Telephone questioning of witnesses was not foreseen by cantonal law.
