I guess I ruffled some feathers here.
To clarify, I was just trying to help explain to the OP what the law actually is, rather than what some of us might wish it to be. I don't think that's "encouraging him to sue" - on the contrary, most likely he'll realize upon further research that there's no case and any attempt to sue will be thrown out on summary judgment. That's what happens with something like 99% of ski injuries. Is this incident one of the 1%? I don't know and can't possibly know given the facts at my disposal. But "no" would be the smart way to bet.
