Key legal question
Whether the pension could be revised under Art. 17 ATSG due to a relevant change in health or adaptation to pain.
Extracted holding
No. The medical evidence showed essentially unchanged findings; the new work-capacity assessment was only a different appraisal of the same situation.
Extracted reasoning
A revision requires a significant change in the factual circumstances. Here the expert himself stated that the clinical findings were largely unchanged and that the higher work-capacity estimate was not based on a proven improvement.
