Kernrechtsfrage
Whether the disability pension revision lawfully reduced the full pension to a half pension as of 1 January 2006.
Extrahierter Entscheid
The revision was lawful; the medical evidence established a relevant change in health and a 50% work capacity in adapted work, corresponding to a 55% disability degree.
Extrahierte Begründung
The psychiatric expert report of 2 October 2005 was found fully probative. Contrary reports lacked diagnostic and evidentiary weight, and later submissions were irrelevant because the decisive period ended with the objection decision. No further investigation was required.
