Kernrechtsfrage
Whether the insurer was entitled to end the disability pension as of 31 August 2004 for lack of natural causal link
Extrahierter Entscheid
The medical evidence established that the accident-related cervical syndrome had ceased to play any role after the August 2004 surgery; the pension could therefore be ended prospectively.
Extrahierte Begründung
The court relied on the 2005 multidisciplinary report, supported by treating physicians, showing a significant improvement and disappearance of the accident-related complaints. A rent revision is only possible for the future; the exact cutoff date was not decisive here.
