Kernrechtsfrage
Whether the revision of the disability pension and reduction to a three-quarter pension was lawful.
Extrahierter Entscheid
Yes. The insured remained capable of 50% work in a light, alternating job, and the diagnosed somatoform pain disorder did not add further invalidating incapacity.
Extrahierte Begründung
The medical evidence was consistent. Reports noted aggravation and secondary gain, so the pain disorder was not a separate disabling factor. No deterioration after the expert assessment was shown, and the calculated disability degree of 67% remained unchanged.
