Kernrechtsfrage
Whether the insured showed a materially worsened health condition justifying revision of the ongoing disability pension.
Extrahierter Entscheid
No. The medical and functional condition was not shown to have materially deteriorated during the relevant period.
Extrahierte Begründung
The lower court correctly assessed the evidence and found that, despite brain-tumor surgery in March 2005, the condition remained essentially unchanged compared with the preoperative period. The new medical note filed in the federal proceedings was late and inadmissible.
