Key legal question
Whether the 2008 reported relapse was in natural and adequate causal connection with the 1988/1989 accidents.
Extracted holding
The relapse was causally linked to the insured accidents; the insurer must provide statutory benefits.
Extracted reasoning
The Federal Court upheld the court-appointed expertise, which convincingly found a traumatic L5/S1 disc injury, persistent bridge symptoms, and no return to status quo ante or sine.
