Kernrechtsfrage
Whether Dr. X. had to be rejected as an expert for bias in the planned psychiatric assessment.
Extrahierter Entscheid
Yes. Given the earlier serious errors in the report and the later, unsubstantiated attribution of those errors to alleged non-cooperation by the claimant, objective doubts about impartiality were warranted.
Extrahierte Begründung
The Court held that prior involvement alone does not establish bias, but the combination of an unsound prior expertise, the expert's defensive statement, and the reproach of non-cooperation not supported by the file objectively undermined confidence in future impartiality.
