Kernrechtsfrage
Whether further medical and vocational investigations were required, including an expert hearing and reimbursement of the private neurological report costs.
Extrahierter Entscheid
The existing expert evidence was sufficient; the refusal to order further investigations was permissible anticipatory assessment, and no reimbursement of the private report costs was due.
Extrahierte Begründung
The neurochirurgical and neuropsychological reports were coherent, based on complete records, and not undermined by the private report; no objectively verifiable doubts justified a court expert.
