Questione giuridica chiave
Whether the conditions for a pension revision under Art. 17 LPGA were met
Decisione estratta
No. The medical and factual situation had not changed in a legally relevant way compared with the materially examined decision of 29 August 1994.
Motivazione estratta
The correct comparison point was the 1994 maintenance decision, not the original 1993 grant. Medical evidence showed the insured was already capable of adapted full-time work in 1993/1994, so the later 2006 findings did not establish a relevant change.
