Questione giuridica chiave
Whether the disability pension was properly revoked in a revision procedure as of 31 May 2009.
Decisione estratta
The revision requirements were met because the relevant comparison period was 2004 and the medical evidence showed a material improvement in health and work capacity by 2009.
Motivazione estratta
Under Art. 17 ATSG, the decisive comparison is between the situation at the last legally relevant pension review and the situation at the revocation decision. The psychiatric and neurological reports established improved mental status and full capacity for adapted work; no substantiated grounds undermined that assessment.
