Question juridique clé
Whether the cantonal court wrongly assessed the medical evidence and should have ordered a multidisciplinary expert opinion.
Solution extraite
The appellant did not show that the cantonal court’s assessment of working capacity was unsustainable; no further evidentiary proceedings were required.
Motifs extraits
The expert report was probative under the case-law criteria, and its conclusions were corroborated by later hearing evidence. Mere disagreement with the file assessment was insufficient.
