Kernrechtsfrage
Whether the insured showed a relevant deterioration justifying a higher disability pension from April 2005.
Extrahierter Entscheid
No. The court upheld the finding that the somatic condition had not materially worsened and that psychiatric incapacity was only established from 6 October 2005, after the relevant date.
Extrahierte Begründung
The assessment of work capacity was a factual finding binding on review absent obvious error. The evidence did not show a legally relevant worsening by the date of the contested decision; a mere suspicion of psychological illness could not replace a medical diagnosis. Any later deterioration had to be examined in a new revision procedure.
