Questione giuridica chiave
Whether the cantonal court's findings on work incapacity were legally sustainable on the medical evidence.
Decisione estratta
The cantonal court was entitled to prefer the administrative psychiatric expert opinion over the private doctors and treating physicians.
Motivazione estratta
Psychiatric assessment involves a wide margin of medical judgment. The dispute concerned the severity of the depressive disorder and its impact on work capacity, not merely diagnosis. The appellant's objections did not show arbitrariness or federal-law error in the evidentiary assessment.
