Kernrechtsfrage
Whether the insured's health improved enough between 2004 and 2009 to justify revision of the disability pension under Art. 17 ATSG.
Extrahierter Entscheid
Yes. The court held that the expert report of 17 March 2009 convincingly showed a relevant improvement in mental health and a remaining 50% incapacity in the former occupation.
Extrahierte Begründung
The alleged mild intellectual impairment was already known or at least accounted for in the medical assessments. The experts expressly considered the claimant's limited personal resources and rejected a mental retardation diagnosis. No arbitrariness was shown in relying on the later expert report.
