Kernrechtsfrage
Whether the psychiatric expert report was invalid because a psychologist participated in the examination and signed the report.
Extrahierter Entscheid
The psychologist's limited participation in gathering background information did not breach the statutory requirements for the expert opinion; the decisive assessment was made by the expert himself.
Extrahierte Begründung
Article 56 StGB requires a qualified expert opinion, but does not prohibit internal assistance by a psychologist who merely conducts preliminary inquiries and anamnestic data collection. The record showed that the psychologist was a qualified psychologist, performed only part of the explorations, and did not author the substantive evaluation.
