Kernrechtsfrage
Whether the pension revision was supported by a sufficiently established improvement in health and work capacity
Extrahierter Entscheid
The file did not sufficiently establish the decisive medical facts; a polydisciplinary expert assessment was required before deciding on revision.
Extrahierte Begründung
The medical reports relied on by the IV office and the lower court were too remote, incomplete regarding work capacity, or based on inadequate review. RAD file opinions and non-specialist reports did not meet evidentiary requirements.
