Lol Derf, Silvio is very much immune. He had a law approved which grants the most important political figures of Italy (President, prime minister, secretary of state and such) COMPLETE immunity. As long as he doesn't shoot someone in the middle of the Vatican in front of thousands of ppl's eyes Berlusconi can't be brought to court. And likewise can he commit tons and tons of fraud without being sueable.
He had that law approved when he was in danger of being convicted in a huge scandal, and he stalled that lawsuit as long as possible until the law was passed, with 2 hour monologues about nothing.
By the time he's no longer in charge he'll prolly have swapped the most important judicial posts with his men, so he'll prolly slip away anyhoo, again.
Hehe...gotta love them southern european countries; Italy, Greece, Spain, Portugal etc. Their politics are more of a charade than anything else.
