Key legal question
Whether the shoulder condition remained causally linked to the insured accidents after 1 February 2007
Extracted holding
The medical expertise relied on by the insurer was internally inconsistent and not sufficiently convincing to disprove natural causation; the remaining shoulder impairment was still causally linked to the 6 November 2002 accident.
Extracted reasoning
The expert acknowledged a partial causal contribution of the accident and described the injury as a pre-existing condition aggravated by the accident, but his statements about a non-guaranteed cure and a later statu quo sine conflicted. The court therefore upheld causation.
