Earlier quoted context omitted.
I know why statutes of limitation exist. I was wondering why it applied here. Apparently it wasn't completely straightforward, as nine jurors were needed to reach a decision on that point, instead of a single judge or even clerk.
Whether the claim accrued before the statute of limitations expired is a question of fact, and is therefore reserved for the fact-finder which in this case was the jury.
I guess there could be a question of fact in a case where the statues of limitation differ for different injuries, and the factual question is which injury was it.
