Key legal question
Whether the conditions for a pension revision under Art. 17 LPGA were met
Extracted holding
No. The medical and factual situation had not changed in a legally relevant way compared with the materially examined decision of 29 August 1994.
Extracted reasoning
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.
