This Green Bay WI news article would be just another garden-variety "overturned on a technicality" story, were it not for this amazing revelation:

The “year-and-a-day” law states that if a victim survives more than 366 days, it can be “conclusively presumed that the injury did not cause the death.”

The law dates back about 800 years to the common-law era and went in effect when Wisconsin was a territory.

Them Indians were a lot more clever than you folks realize!
