Kernrechtsfrage
Whether the revision of the disability pension from a full pension to a three-quarter pension was lawful.
Extrahierter Entscheid
The revision was lawful because the medical evidence showed a relevant change in the claimant's work capacity and the resulting disability rate did not reach the threshold for a full pension.
Extrahierte Begründung
The court upheld the lower court's assessment that the claimant had full capacity for light work from a rheumatological perspective and a 50% psychiatric limitation. The evidence was sufficiently reliable, and a separate pain expert opinion was unnecessary because subjective pain intensity was not decisive for work capacity.
