Key legal question
Whether the authorities violated the duty to investigate by failing to order neuropsychological examinations.
Extracted holding
No. The file contained no clear indications of neurological or neuropsychological impairment, and the existing expert reports did not make further clarification necessary.
Extracted reasoning
The later neuropsychological report did not make the earlier decision-based record incomplete. The psychiatric, internal medicine, and orthopedic findings were not manifestly incorrect, and the cantonal court's evidentiary assessment was at least defensible.
