Well, the definition is one thing. What we really need, though, is the statute of limitations on cases based on false advertising. Effectively, we need to know if a class action lawsuit could be filed on false advertising that happened in the late 70s/early 80s. But there might be a loophole that could be exploited by saying that we were not given information that this advertising was truly "false" until just this past year in which case we wouldn't need to worry about statute of limitation. If it was false advertising back in 77/80/83, we would have had no way of knowing because Lucas never said it or gave any indication of it until just this past year.
