Kernrechtsfrage
Whether the insured's residual work capacity after September 2003 justified a pension claim
Extrahierter Entscheid
The MEDAS assessment of 50% work capacity in adapted work was not seriously undermined; the claimed lower practical capacity was not proven.
Extrahierte Begründung
The treating physician's reports did not consistently support a lasting substantially lower capacity, so the well-reasoned MEDAS opinion remained convincing.
