Hi,
I have been writing something about legal issues about online gambling in Europe. And I found, that it is messy problem because of Europe Union.
There was a similar problem in Italy, in 2003 called Gambelli Case. The State prosecuted Stanley co.´s affiliate in Italy, because accepting bets in Italy was (is?) reserved to the state.
Gambelli (affiliate ) won this case, because there is article about free trade between states etc. in EU law.
I am from Czech rep. where online gambling is illegal too and know many cases, inculding well-known Bet and Win Comp. where courts did not prosecuted companies till now.
You can learn more about Gambelli Case here: http://www.internationallawoffice.com/Newsletters/detail.aspx?g=49146ae2-535d-4f74-9177-810e5f14c66a
This works in the case your casino aff program is located in EU countries
