Kernrechtsfrage
Whether the insured remained entitled to an invalidity pension after 31 March 2005.
Extrahierter Entscheid
No; the medical evidence supported improved capacity to work, so the pension could be ended after 31 March 2005.
Extrahierte Begründung
The expert report of B. and O. was considered probative. Even taking a 75-80% work capacity with a 20% loss of efficiency, the degree of invalidity remained below the pension threshold. The treating physicians' certificates did not convincingly outweigh the expert evidence.
