Kernrechtsfrage
Whether the conditions for revision of the disability pension under Art. 17(1) ATSG were met
Extrahierter Entscheid
No legally relevant change in the facts affecting earning capacity was established; the existing quarter pension remained unchanged.
Extrahierte Begründung
Although the medical diagnosis evolved, the decisive work capacity for adapted light work remained at 80%, and the claimant failed to show a relevant deterioration compared with the comparison date.
