It doesn't matter since he agreed to the parole agreement. He violated it plain and simple. Now the real question would be if he gets to keep the money. I'm sure the state will do everything in its power to return that money to the general fund for pork...I mean good causes...
1. He has the right to keep the money (he won the lottery prize legitimately).
2. He gets sent to jail or faces some other legal consequences for violating the terms of his parole.
I don't see how the terms of his parole have anything to do with what happened subsequently as a result of his violation of those terms (since there was nothing inherently illegal about winning the lottery in and of itself).
