Kernrechtsfrage
Whether the psychiatric expert report could be challenged through a nullity appeal as contradictory, incomplete, or biased.
Extrahierter Entscheid
The complaints attacked the evaluation of evidence and the report itself, which are not reviewable in a nullity appeal.
Extrahierte Begründung
A nullity appeal lies only for violations of federal criminal law, not for challenges to the appraisal of evidence, bias, or alleged omissions in the expert's investigation.
