Questione giuridica chiave
Whether the cantonal court wrongly refused a judicial psychiatric expert report and misassessed the medical evidence.
Decisione estratta
No. The court could rely on the existing medical record because the depressive and personality disorders were already disabling, and the exact role of the addictions was not decisive.
Motivazione estratta
The Federal Court held that addiction is not itself invalidity, but it matters only if it causes or results from a medically relevant disorder. Here, the psychiatric disorders were established as illnesses affecting work capacity, so the disputed characterization of the addictions did not change the outcome.
