Kernrechtsfrage
Whether the pension could be reduced from a whole to a half pension as of 1 June 2004 on revision grounds.
Extrahierter Entscheid
The reduction was justified only if there had been a relevant change in the factual circumstances; here, no such change was shown, but the earlier whole pension was based on an incomplete assessment and could not be extended beyond May 2004.
Extrahierte Begründung
The medical evidence showed the same somatic findings in 2003 and 2004; the changed assessment concerned only work capacity, not a proven health improvement. However, the initial whole pension from August 2003 was not founded on a fully compliant assessment of earning capacity.
