Question juridique clé
Whether the case had to be sent back for further medical investigations, including an independent expert opinion
Solution extraite
No. The cantonal court could reasonably rely on the existing medical evidence and, in anticipatory assessment of evidence, refuse further inquiries.
Motifs extraits
The medical reports were sufficient and coherent; the contested 50% assessment was not convincing, whereas the neurologist's later 30% assessment and the RAD review were adequate. No new deterioration was shown or alleged.
