Kernrechtsfrage
Whether the accident insurer's duty to pay benefits ended on 30 June 2006 because the status quo sine vel ante had been reached.
Extrahierter Entscheid
The insurer failed to prove that the causal effect of the accident had ceased by 30 June 2006; benefits continued beyond that date.
Extrahierte Begründung
Although there was a pre-existing degenerative lumbar condition, the prior pain-free interval after the first operation and the medical evidence made it more probable that the accident remained a concurrent cause until the later surgery.
