Key legal question
Whether the pension revocation was justified by a material change in health under Art. 17 ATSG.
Extracted holding
No material change in the legally relevant sense was established; the psychiatric situation remained essentially unchanged and the somatic deterioration did not justify abolishing the pension under Art. 17 ATSG.
Extracted reasoning
The court preferred the later comprehensive judicial expert report, which found no relevant psychiatric work incapacity and only somatic limitations that still allowed adapted full-time work. The earlier full pension had been based mainly on a pain syndrome with depressive component, and the current record did not show a qualifying revision ground.
