Questione giuridica chiave
Whether the conditions for revising and abolishing the invalidity pension under Art. 17 LPGA were met
Decisione estratta
No. The medical situation had remained essentially unchanged; the expert report reflected only a different assessment, not a relevant change in circumstances.
Motivazione estratta
A revision requires a notable change in health or earning capacity. The record did not show objective improvement, and the experts could not establish retroactively that the insured had recovered work capacity after 1992.
