While I think most four year olds would understand that someone could get hurt if you run into them with a bike, I also understand that children that age are easily caught up in the moment, and these two were probably not focused on anything beyond who was winning the race.
Really, it's the moms at fault here. While they were apparently not encouraging the children to race, it doesn't seem they were trying to stop it either. And to kids that age, not saying No is the same as saying Yes.
Whether four and five year olds should be sued wasn't the question, though. It was if they could be, and under these cirumstances, apparently they can. Although this part of the judge's ruling makes me wonder who's padding the bill...
Mr. Tyrie “correctly notes that infants under the age of 4 are conclusively presumed incapable of negligence,” Justice Wooten wrote in his decision, referring to the 1928 case. “Juliet Breitman, however, was over the age of 4 at the time of the subject incident. For infants above the age of 4, there is no bright-line rule.”
Mr. Tyrie is the attorney for the kid, and it seems so simple that the kid was over the age of four that I can't believe he thought it would fly.
I keep wondering about why someone would sue kids that young in addition to the parents. Could there be a larger settlement from a liability policy if two occupants of the household were found negligent for the same event? Wait, would a policy even pay if you were found negligent?
If a kid hit and seriously injured my grandmother with a bike, I think my reaction would depend largely on the reaction of the parents. If they were genuinely sorry and made the kids take some sort of age-appropriate responsiblity (draw Grandma a picture, apologize), I'd be a lot less likely to pursue legal action. Especially after Grandma passed away from unrelated causes.
If, however, they implied that Grandma should've gotten out of the way, and that the fault was hers...well, that would really piss me off.
