Questione giuridica chiave
Whether the AI pension had to be revised and increased to a full pension due to an alleged deterioration or economic inability to exploit residual earning capacity.
Decisione estratta
No revision was warranted because the medical situation had remained essentially unchanged; a merely different assessment of the same facts does not justify material revision.
Motivazione estratta
The expert report confirmed an unchanged clinical situation. The appellant's reliance on a different vocational-economic assessment and on new facts was not admissible before the Federal Tribunal.
