This guy is guilty of paying $160k for work that reasonably would have cost up to $150k ???   

Something I don't understand here.

Am I correct that the crux of the case against Stevens was that he got some work done to his house for a reduced cost as part of some kind of kick-back?

What exactly were the 7 charges against him?

The residential contractor who finished the renovation for VECO, Augie Paone, "believes the [Stevens'] remodeling could have cost ― if all the work was done efficiently ― around $130,000 to $150,000, close to the figure Stevens cited last year."[62] The Stevens paid $160,000 for the rennovations "and assumed that covered everything.

So was there any question Stevens paid the $160k he claimed?

If he did, and if the work is reasonably valued at $150k, then how on earth can the prosecution claim he got some sort of unreported gift or illegal kickback?
