Question juridique clé
Whether the cantonal court acted arbitrarily in preferring the judicial psychiatric expertise over the administrative medical expert opinion.
Solution extraite
No arbitrariness was shown; the court could rely on the judicial expertise because it was reasoned, addressed differential diagnoses, and was corroborated by oncology specialists.
Motifs extraits
Federal review is limited to arbitrariness. The judicial expert explained why the symptoms were credible, excluded other causes, and supported his conclusions with medical literature and specific testing. The appellant's objections were unsubstantiated.
