Kernrechtsfrage
Whether the revision-based reduction of the disability pension was lawful.
Extrahierter Entscheid
The reduction was lawful; the appeal court found no grounds to overturn the revised assessment.
Extrahierte Begründung
The original 2002 decision was the relevant comparison point because the 2004 confirmation was only summary. The medical findings supported an improved earning capacity, and the 15% deduction in the income comparison was within discretion.
