Kernrechtsfrage
Whether the Obergericht’s reliance on the 21 January 1998 medical report was arbitrary.
Extrahierter Entscheid
No. The court could rely on the later report despite an earlier contrary expert opinion because the claimant did not show concrete defects in the later report and the medical situation could have changed over time.
Extrahierte Begründung
A later medical assessment may supersede an earlier one; disagreement with prior reports alone does not make the later report unreliable or the appraisal arbitrary.
