Kernrechtsfrage
Whether the medical evidence was sufficient to assess the insured's residual work capacity and disability degree for the pension period from 2003 to 2004.
Extrahierter Entscheid
No; the earlier medical assessment did not reliably exclude a relevant deterioration before the opposition decision, so further investigations were required.
Extrahierte Begründung
The 2002 assessment was convincing for that time, but later reports indicated possible worsening. The August 2004 statement was cautious and based only on files, while the 2005 final examination and another doctor's report suggested a deteriorated shoulder condition. Anticipatory appreciation could not rule out a relevant change with sufficient certainty.
