I think the case of the sprained ankle/horses/fence was a raw deal. If someone is on my property and tripped on a rock, then they sued me, I'd be pissed. It seems unfair to me - clumsy equals I pay for your ER bill, do I have to clear every little obstacle so no mishaps can befall any visitor ever?
After hearing the details, JJ made the defendant (partly) responsible. Whatever, JJ. I've never been a homeowner, so if I'm missing some statute, I'd be curious to find out how this case fits.
