Kernrechtsfrage
Whether a revision ground existed for reducing the disability pension.
Extrahierter Entscheid
A revision ground existed because the insured's health and earning capacity had materially changed compared with the earlier reference point.
Extrahierte Begründung
The court held that the relevant comparison point was the last final decision based on proper assessment. The medical record and the insured's own plans to resume work showed a significant improvement in psychological condition before the 2004 accident, and the later accident did not eliminate the prior revision ground.
