Year and a day example

On March 15, Jim slips poison into Steve's drink.  Steve survives after medical treatment but has to fight off many infections because of a weakened immune system.  On June 5 of the following year, Steve dies from the flu.

Prosecutors charge Jim with second degree murder, but the trial court dismisses the charge because of the state's year and a day rule.  Because Steve died more than a year and a day after Jim poisoned him, no homicide charges can be brought. 

Prosecutors appeal to the highest court in the state, but that court affirms the trial court's holding.  Because of the rule's long history in the state, the court refuses to abolish it retroactively.  The court suggests that the legislature might wish to re-examine the rule and abolish it going forward.
