Well, UIGEA states that it is illegal for banks to process money related to ILLEGAL ONLINE GAMBLING.
However, only sports betting is actually illegal. There are no federal laws concerning poker or casino games.
Each state that prohibits poker or casino games could sue independently based on their own laws, but there is no federal law.
The DOJ would have to prove that firstly, poker is not a skill game, and secondly, that online poker is illegal.
They can’t prove online poker is illegal except in some individual states.
So, either it will be pursued only on the state level, or it would be a very long, drawn out thing in the courts. I doubt the DOJ wants that.
So – what I see is shock and awe. And perhaps a state taking the poker rooms to court – if they can get a hold of them. Really, what will likely happen is that they will settle and another state will walk off with full coffers.
