Key legal question
Whether the insurer proved that the status quo sine vel ante was reached by 31 October 2009
Extracted holding
The existing file did not establish with sufficient probability that the causal link had ceased by 31 October 2009; further orthopedic expertise was required.
Extracted reasoning
The prior medical opinion did not answer the decisive question for all relevant events. A mere possibility of non-causation was insufficient; the insurer bore the burden to prove the end of causal relevance.
