Kernrechtsfrage
Whether the defendant's confrontation rights were violated because the complainant did not appear at trial in person.
Extrahierter Entscheid
No violation occurred because the complainant was heard by police specialist in the presence of a court delegation, and the defendant had the opportunity to participate and ask additional questions but did not use it.
Extrahierte Begründung
Article 6(3)(d) ECHR and the corresponding constitutional guarantees are satisfied if the accused has at least one adequate opportunity to challenge the witness and put questions; this was afforded here.
