Questione giuridica chiave
Whether the insured's psychiatric condition had improved enough to justify revising the disability pension.
Decisione estratta
The medical reports were sufficient and concordant to establish a psychiatric improvement compared with the situation when the full pension was granted; the challenged finding was not arbitrary.
Motivazione estratta
The treating and examining doctors knew the medical history, conducted adequate examinations, and consistently described a better psychiatric status. The post-decision reports could not rebut the improvement and, in any event, diagnosed conditions considered overcome by reasonable willpower.
