(disclaimer- I don't care about this. it's interesting, and that's about all)
From the pamphlet -
Q: Will injuries sustained during work-related travel be compensated?
A: Whether or not a travel-related injury will be compensated depends on the nature of the travel involved. Under the so-called "going and coming" rule, where an employee has a fixed place of employment, an injury sustained while traveling to or from that place of employment will not be covered. However, where travel is an integral part of the employment, and creates a risk greater than the typical commute, an injury sustained during the travel will be covered (e.g., a traveling salesperson with no fixed place of employment).
So, I read this to indicate that if DMC was travelling as a part of his employment (and I had been under the impression that he was, having left a news conference that was held during the snow outside of business hours) that the injury/death is covered. Further, he was driving a company vehicle.
That said, there's the question - did the cardiac arrest happen before the crash and cause it or vice versa? Without medical evidence, who owns the burden of proof? This line - "2) injury or disability caused primarily by the natural deterioration of tissue, an organ, or part of the body" disallows payment under those circumstances, which means if it's the former situation then there's no payout.
It'll be interesting to see where this goes.
