lol, no it isn't. No court is ever going to hear about this insane drivel.
You made a statement of fact on a legal matter, which is not up to us to decide about. And again, that's not up to us to decide if his statements would hold up in a court of law. In fact, there's been a case against as video game critic that is pretty much the same thing, AND they WERE heard in court. Of course, they lost, because their case had no merit, but a court DID listen to it.
Again, it's not up to us to decide whether or not Mr. Kelley has a case, it's up to a judge.
Or a multi volume fantasy novel series that leaves its readers hanging for decades...
Still bitter about Robert Jordan? Or are you talking Jim Butcher or George Martin?
