Questione giuridica chiave
Whether the 2018 pension reduction was justified by a relevant change in health and earning capacity.
Decisione estratta
No materially relevant improvement in the cardiac condition was proven; the revision ground failed.
Motivazione estratta
The earlier award had been based essentially on the cardiac situation. The 2016 expert opinion and the expert's later clarification did not show a real improvement compared with the situation underlying the 2011 full pension award; rather, the coronary disease remained progressive. Without a proven change relevant to entitlement, revision under Article 17 ATSG was excluded.
